| 1 | 沁水盆地煤储层微裂隙发育的煤岩学控制机理显示文摘基于沁水盆地主要矿区实测煤样的分析资料,总结了煤岩显微组分、煤岩类型和煤相与微裂隙发育的关系,探讨了微裂隙的成因及煤岩学控制机理.结果表明:该区微裂隙多以长度小于300μm,宽度小于5μm的裂隙为主,裂隙密度一般都在10~50条/9cm2之间;微裂隙通常发育于均质镜质体为主的组分中,且常见于条带状亮煤或以微镜煤为主的亮煤中.潮湿、弱氧化和弱水动力的成煤环境有利于微裂隙的发育.微裂隙是煤化作用过程中烃类气体的瞬间积聚形成高压流体单元后突然破裂而形成的,其中条带状亮煤或以均质镜质体为主的流体微单元,不仅具有较好的生烃潜能,同时孔隙发育差不利于气体的扩散,这是造成这些组分中微裂隙发育的主要原因. | 姚艳斌 刘大锰 汤达祯 唐书恒 黄文辉 | 2010 | 中国矿业大学学报2010,39,1: | 53 |
| 2 | 中国煤储层渗透率主控因素和煤层气开发对策显示文摘我国煤储层渗透率比美国煤储层渗透率低1~2个数量级,低渗透率是制约我国煤层气勘探开发的主要因素之一,本文系统分析了我国煤储层渗透率的主控因素。研究表明,煤储层的渗透率主要受煤体结构、宏观裂隙以及割理/裂隙系统充填状况和现今地应力等因素的控制,适度构造变形产生的碎裂煤中因宏观裂隙发育导致其渗透率高于原生结构煤的渗透率,但强烈构造变形形成的碎粒煤和糜棱煤则使渗透率降低;割理/裂隙系统矿物充填和高应力不利于渗透率保存。在不同地区,控制煤储层渗透率的关键因素不同,针对性对策是煤层气开发的关键:针对复杂煤体结构,在压裂井层优选时要在煤体结构测井解释的基础上考虑避开糜棱煤;针对我国华北地区石炭—二叠系煤层割理/裂隙普遍以方解石充填为主的煤储层低渗透成因,建议探索和开发酸化压裂一体化储层增透技术;针对高应力和地应力类型在垂向上的转换,在压前搞清应力强度和类型的基础上,控制水力压裂隙高度以避免沟通煤层围岩含水层;针对煤储层的应力敏感性和高应力状态,建议采用逐级降压制度,以提高单井的累计产气量。 | 康永尚 孙良忠 张兵 顾娇杨 叶建平 姜杉钰 王金 毛得雷 | 2017 | 地质论评2017,63,5: | 46 |

| 6 | 基于主地质参数的煤层气有利开发区优选及应用显示文摘煤层气有利开发区既是煤层气富集区、高渗区,又是煤层气高产区,因此寻找能表征煤层气富集区、高渗区和高产区的主地质参数,是解决煤层气有利区优选问题的关键。基于区块尺度的煤层气有利区优选,建立了一种定量化的综合评价方法:(1)以含气量、储层压力、临界解吸压和试井渗透率为主地质参数并作为评价指标,以煤层气井稳产阶段平均日产气量作为衡量指标,采用灰色关联度分析法定量地确定各评价指标的权重系数以及评价值函数;(2)借助于MapInfo professional软件,计算煤层气区任意位置的综合评价值;(3)用产气量对综合评价值进行标定,确定煤层气开发区类型及分布范围。将该方法应用于沁水盆地南部勘探程度较高的郑庄区块,预测出煤层气有利开发区(产气量>2 000 m3/d)的分布范围,研究结果对于下一步的煤层气钻井部署具有一定的参考意义。 | 李俊乾 刘大锰 姚艳斌 蔡益栋 郭晓茜 | 2014 | 现代地质2014,28,3: | 18 |
| 7 | 沁水盆地南部煤储层显微裂隙发育的影响因素显示文摘为研究沁水盆地南部3号和15号煤储层显微裂隙的发育情况,借助扫描电镜显微裂隙分析、荧光显微镜显微裂隙统计、X射线衍射分析等手段,总结了地应力、煤岩显微组分、煤变质程度、煤中矿物质与显微裂隙发育的关系,探讨了影响煤储层显微裂隙发育主要因素。结果表明,该区煤储层显微裂隙较为发育,显微裂隙密度一般为7~59条/9 cm^2,以C型和D型裂隙为主,扫描电镜下常见张性裂隙、剪性裂隙,对煤储层渗透性贡献较大,内生裂隙较少见。显微裂隙通常发育于镜质组中,裂隙密度随变质程度的升高表现出降低的趋势,煤中矿物的充填作用对于显微裂隙的发育影响较大,对煤样渗透性造成了直接破坏作用,地应力场的方向和大小控制着外生显微裂隙的开合程度,进而对煤储层的渗透性产生影响。因此认为,地应力和煤中矿物是影响该区煤储层显微裂隙发育的主要因素。 | 胡咤咤 黄文辉 刘素平 张谦 许启鲁 冯小龙 | 2016 | 煤田地质与勘探2016,44,5: | 10 |

| 10 | Geological Controls on the CBM Productivity of No.15 Coal Seam of Carboniferous–Permian Taiyuan Formation in Southern Qinshui Basin and Prediction for CBM High-yield Potential Regions显示文摘Coalbed methane(CBM) resources in No.15 coal seam of Taiyuan Formation account for 55% of the total CBM resources in southern Qinshui Basin(SQB), and have a great production potential. This study aims at investigating the CBM production in No.15 coal seam and its influence factors. Based on a series of laboratory experiments and latest exploration and development data from local coal mines and CBM companies, the spatial characteristics of gas production of No.15 coal seam were analyzed and then the influences of seven factors on the gas productivity of this coal seam were discussed, including coal thickness, burial depth, gas content, ratio of critical desorption pressure to original coal reservoir pressure(RCPOP), porosity, permeability, and hydrogeological condition. The influences of hydrological condition on CBM production were analyzed based on the discussions of four aspects: hydrogeochemistry, roof lithology and its distribution, hydrodynamic field of groundwater, and recharge rate of groundwater. Finally, a three-level analytic hierarchy process(AHP) evaluation model was proposed for predicting the CBM potentials of the No.15 coal seam in the SQB. The best prospective target area for CBM production of the No.15 coal seam is predicted to be in the districts of Panzhuang, Chengzhuang and south of Hudi. | ZHANG Zheng QIN Yong ZHUANG Xinguo LI Guoqing LIU Donghai | 2018 | Acta Geologica Sinica(English Edition)2018,92,6: | 5 |
| 11 | 欠饱和煤储层气水有效渗透率动态变化规律显示文摘为准确量化正负效应对相渗曲线的影响,采用欠饱和物质平衡方程,将改进的PMG绝对渗透率模型与CPL相对渗透率模型在相同储层压力与含水饱和度下耦合,建立了考虑水侵的欠饱和煤储层有效渗透率动态预测模型,并分析了气水有效渗透率动态变化规律.研究表明:模型将有效渗透率统一为储层压力的函数,能很好反映煤储层正负效应,特别是基质收缩对于气相有效渗透率的改善作用;水侵引起净产水减少,导致含水饱和度降低变缓,抑制气相有效渗透率的升高与水相有效渗透率的下降,但对曲线形态影响微弱;若水侵量不再变化,定速水侵就转化为定量水侵.适当提高排水速度有助于降低水侵的影响. | 赵俊龙 汤达祯 许浩 孟艳军 | 2014 | 辽宁工程技术大学学报(自然科学版)2014,33,8: | 5 |
| 12 | Prediction of Flowing Bottomhole Pressures for Two-Phase Coalbed Methane Wells显示文摘A method is proposed to predict the flowing bottomhole pressures(FBHPs)for two-phase coalbed methane(CBM)wells.The mathematical models for both gas column pressure and two-phase fluid column pressure were developed based on the well liquid flow equation.FBHPs during the production were predicted by considering the effect of entrained liquid on gravitational gradients.Comparison of calculated BHPs by Cullender-Smith and proposed method was also studied.The results show that the proposed algorithm gives the desired accuracy of calculating BHPs in the lowproductivity and low-pressure CBM wells.FBHP is resulted from the combined action of wellhead pressure,gas column pressure and fluid column pressure.Variation of kinetic energy term,compressibility and friction factors with depth increments and liquid holdup with velocity should be considered to simulate the real BHPs adequately.BHP is a function of depth of each column segment.The small errors of less than 1.5%between the calculated and measured values are obtained with each segment within 25 m.Adjusting BHPs can effectively increase production pressure drop,which is beneficial to CBM desorption and enhances reservoir productivity.The increment of pressure drop from 5.37 MPa2 to 8.66 MPa2 leads to an increase of CBM production from 3270 m3/d to 6700 m3/d and is attributed to a decrease in BHP from 2.25 MPa to 1.33 MPa. | LIU Xinfu | 2013 | Acta Geologica Sinica(English Edition)2013,87,5: | 5 |

| 16 | Seismic studies of coal bed methane content in the west coal mining area of Qinshui Basin显示文摘The coal bed methane content(CBMC)in the west mining area of Jincheng coalfield,southeastern Qjnshui Basin,is studied based on seismic data and well-logs together with laboratory measurements.The results show that the Shuey approximation has better adaptability according to the Zoeppritz equation result;the designed fold number for an ordinary seismic data is sufficient for post-stack data but insufficient for pre-stack data regarding the signal to noise ratio(SNR).Therefore a larger grid analysis was created in order to improve the SNR.The velocity field created by logging is better than that created by stack velocity in both accuracy and effectiveness.A reasonable distribution of the amplitude versus offset(AVO)attributes can be facilitated by taking the AVO response from logging as a standard for calibrating the amplitude distribution.Some AVO attributes have a close relationship with CBMC.The worst attribute is polarization magnitude,for which the correlation coefficient is 0.308;and the best attribute is the polarization product from intercept,of which the correlation coefficient is-0.8136.CBMC predicted by AVO attributes is better overall than that predicted by direct interpolation of CBMC;the validation error of the former is 14.47%,which is lower than that of the latter 23.30%.CBMC of this area ranges from2.5 m^3/t to 22 m^3/t.Most CBMC in the syncline is over 10m^3/t,but it is below 10m^3/t in the anticline;on the whole,CBMC in the syncline is higher than that in anticline. | Zou Guangui Peng Suping Yin Caiyun Xu Yanyong Chen Fengying Liu Jinkai | 2013 | International Journal of Mining Science and Technology2013,23,6: | 2 |
| 17 | 基于地震多属性的郑庄区块煤层气开发甜点区优选显示文摘地震属性受多种地质因素的影响,单一地震属性很难准确地反映煤层气储层综合地质特征。寻找能够降低地震属性多解性的方法,准确预测主地质参数,是评价煤层气有利区的关键。根据煤层厚度、含气量和渗透率分别与振幅类、频率类和曲率类地震属性具有较高相关性的特点,通过地震多属性组合变换的方法,建立了基于地震属性分析的煤层气主地质参数预测模型。然后,建立动态权重系数中值法,以中值评价值出现的最高频率,确定主地质参数在煤层气有利区优选中所占的权重,并基于评价值函数实现有利开发区块优选。利用该方法对沁水盆地郑庄地区的预测结果表明:最有利开发甜点区位于北部的59-60-57-55井区,次级有利开发甜点区位于东北部的53-62-49-45井区。 | 杨延辉 姚艳斌 王辉 陈龙伟 | 2016 | 现代地质2016,30,6: | 2 |
| 18 | Prediction Model of Coal Reservoir Pressure and its Implication for the Law of Coal Reservoir Depressurization显示文摘The main methods of coalbed methane(CBM)development are drainage and depressurization,and a precise prediction of coal reservoir pressure is thus crucial for the evaluation of reservoir potentials and the formulation of reasonable development plans.This work established a new reservoir pressure prediction model based on the material balance equation(MBE)of coal reservoir,which considers the self-regulating effects of coal reservoirs and the dynamic change of equivalent drainage area(EDA).According to the proposed model,the reservoir pressure can be predicted based on reservoir condition data and the actual production data of a single well.Compared with traditional reservoir pressure prediction models which regard EDA as a fixed value,the proposed model can better predict the average pressure of reservoirs.Moreover,orthogonal experiments were designed to evaluate the sensitivity of reservoir parameters on the reservoir pressure prediction results of this proposed model.The results show that the saturation of irreducible water is the most sensitive parameter,followed by Langmuir volume and reservoir porosity,and Langmuir pressure is the least sensitive parameter.In addition,the pressure drop of reservoirs is negatively correlated with the saturation of irreducible water and the Langmuir volume,while it is positively correlated with porosity.This work analyzed the reservoir pressure drop characteristics of the CBM wells in the Shizhuangnan Block of the Qinshui Basin,and the results show that the CBM reservoir depressurization can be divided into three types,i.e.,rapidly drop type,medium-term stability type,and slowly drop type.The drainage features of wells were reasonably interpreted based on the comprehensive analysis of the reservoir depressurization type;the latter was coupled to the corresponding permeability dynamic change characteristics,eventually proving the applicability of the proposed model. | YAN Xinlu ZHANG Songhang TANG Shuheng LI Zhongcheng WANG Kaifeng YI Yongxiang DANG Feng HU Qiuping | 2019 | Acta Geologica Sinica(English Edition)2019,93,3: | 2 |
