| 3 | 塔河油田碳酸盐岩储层有效性测井评价实践与思考显示文摘塔河油田奥陶系已经勘探开发十几年了,目前除了在塔河继续精细勘探,也正在加大塔河之外的勘探。近几年塔中、玉北奥陶系碳酸盐岩储层勘探实践表明,储层有效性评价越来越显得重要。针对塔河油田奥陶系碳酸盐岩缝洞型储层,从测井响应特征分析入手,在岩心、成像测井、常规测井相互标定的基础上,细化溶孔、裂缝和溶洞型储层的分类,建立塔河油田奥陶系碳酸盐岩储层有效性测井识别与评价方法。对溶洞型储层采用自然伽马与视地层水电阻率交会方法进行有效性评价。对于裂缝孔洞型储层还可以利用电成像局部电阻率法评价储层有效性。实践表明,这两种方法可以较好解决因泥质充填造成的储层有效性评价问题。对于因储层类型不同,或具体说因裂缝发育强弱造成储层有效性差异的裂缝孔洞型储层有效性评价,通过'四性'关系及数模研究,提出定渗透率、变孔洞孔隙度、变裂缝孔隙度的储层渗流评价模型。实际应用表明,储层渗流评价方法提高了测井解释符合率,为塔里木盆地碳酸盐岩储层有效性评价、完井方案制定和储量参数计算提供了依据。 | 柳建华 蔺学旻 张卫锋 张晓明 | 2014 | 石油与天然气地质2014，35，6： | 18 |
| 4 | Theoretical Progress and Key Technologies of Onshore Ultra-Deep Oil/Gas Exploration显示文摘Oil/gas exploration around the world has extended into deep and ultra-deep strata because it is increasingly difficult to find new large-scale oil/gas reservoirs in shallow–middle buried strata. In recent years, China has made remarkable achievements in oil/gas exploration in ultra-deep areas including carbonate and clastic reservoirs. Some (ultra) large-scale oil and gas fields have been discovered. The oil/gas accumulation mechanisms and key technologies of oil/gas reservoir exploration and development are summarized in this study in order to share China’s experiences. Ultra-deep oil/gas originates from numerous sources of hydrocarbons and multiphase charging. Liquid hydrocarbons can form in ultradeep layers due to low geothermal gradients or overpressures, and the natural gas composition in ultra-deep areas is complicated by the reactions between deep hydrocarbons, water, and rock or by the addition of mantle- or crust-sourced gases. These oils/gases are mainly stored in the original highenergy reef/shoal complexes or in sand body sediments. They usually have high original porosity. Secondary pores are often developed by dissolution, dolomitization, and fracturing in the late stage. The early pores have been preserved by retentive diageneses such as the early charging of hydrocarbons. Oil/gas accumulation in ultra-deep areas generally has the characteristics of near-source accumulation and sustained preservation. The effective exploration and development of ultra-deep oil/gas reservoirs depend on the support of key technologies. Use of the latest technologies such as seismic signal acquisition and processing, low porosity and permeability zone prediction, and gas–water identification has enabled the discovery of ultra-deep oil/gas resources. In addition, advanced technologies for drilling, completion, and oil/gas testing have ensured the effective development of these fields. | Xusheng Guo Dongfeng Hu Yuping Li Jinbao Duan Xuefeng Zhang Xiaojun Fan Hua Duan Wencheng Li | 2019 | Engineering2019，5，3： | 15 |
| 5 | 基于孔隙结构参数的相控渗透率地震预测方法显示文摘针对在储集层孔隙结构复杂、岩相分布非均质性较大情况下采用孔隙度直接线性回归法预测渗透率存在适用性差的问题,提出综合考虑储集层孔隙结构、孔隙度和岩相等因素进行复杂储集层渗透率预测的方法。首先采用储集层段孔隙度、弹性参数及剪切骨架柔度因子进行岩相分析,然后在每类岩相中采用弹性参数、孔隙度及剪切骨架柔度因子进行多元回归得到预测渗透率。通过研究区测井资料渗透率预测实验表明,刻画孔隙结构的剪切柔度因子对渗透率的影响比常规弹性参数敏感,可以更好地用于渗透率预测;岩相分类精度会对渗透率预测产生较大影响,精确地岩相分类仍然是渗透率预测前提条件。实际研究区应用效果验证了基于孔隙结构参数的相控渗透率地震预测方法准确有效,为渗透率预测提供了一种有效方法。 | 甘利灯 王峣钧 罗贤哲 张明 李贤斌 戴晓峰 杨昊 | 2019 | 石油勘探与开发2019，46，5： | 14 |

| 7 | 礁滩相储集层平面非均质性定量表征技术显示文摘受沉积、成岩、构造破裂等作用影响,礁滩相储集层平面非均质性较强,但由于储集层孔隙类型多样,孔—渗关系复杂,储集层渗透率定量预测难度大,加上目前多借用碎屑岩表征参数和表征方法,致使储集层平面非均质性难以定量表征。以普光气田为例,通过分析礁滩相碳酸盐岩储集层非均质性影响因素,运用统计学中的主因子分析方法,优选出颗粒岩厚度百分比、隔夹层个数、孔隙度、基质渗透率、裂缝渗透率五项评价参数;而针对具有复杂孔隙结构特征的礁滩相储集层基质渗透率参数的取值,则引入反映孔隙形态和连通性的'孔构参数',开展储集层渗透率的测井精细解释与地震预测;以四级层序为研究单元级次,优选综合指数法,对井点上储集层非均质参数进行计算;再在传统数理统计方法评价储集层平面非均质性基础上,进一步采用地震预测渗透率反演数据体震控、沉积微相相控的多级约束,运用地质建模技术,定量评价了气田平面非均质性。研究成果较好的指导了气田开发动态分析、措施方案制定等,对气田开发具有重要意义。 | 靳秀菊 侯加根 刘红磊 陈建 刘欣 | 2016 | 地质论评2016，62，5： | 4 |

| 9 | Discovery and theoretical and technical innovations of Yuanba gas field in Sichuan Basin, SW China显示文摘To solve the difficulties in exploration and development in Yuanba ultra-deep gas field in Sichuan Basin,SW China,the article studies the mechanism of quality reef reservoirs development and gas accumulation and innovates techniques in ultra-deep seismic exploration,drilling,completion and testing.Through the reconstruction of dynamic depositional evolution process and regional depositional framework of homoclinal ramp-rimmed platform in Upper Permian,three theories are put forward:first,'early beach-late reef,multiple stacking,arrangement in rows and belts'is the sedimentary mode for the reservoirs in the Changxing Formation of Yuanba area;second,'dissolution in early exposure stage and dolomitization during shallow burial giving rise to the pores in matrix,overpressure caused by cracking of liquid hydrocarbon during deep burial inducing fractures'is the reservoirs development mechanisms;third,'coupling of pores and fractures'controls the development of high quality reservoirs in deep formations.From correlation of oil and source rock,it is concluded that the Wujiaping Formation and Dalong Formation of deep-water continental shelf are the major source rocks in the Permian of northern Sichuan Basin.The hydrocarbon accumulation mode in ultra-deep formations of low-deformation zones is characterized by'three-micro(micro-fault,micro-fracture interbed crack)migration,near-source enrichment,and persistent preservation'.Through seismic inversion using the pore structure parameters of pore-fracture diadactic structure model,the high production gas enrichment area in Yuanba gas field is 98.5 km^2.Moreover,special well structure and unconventional well structure were used to deal with multiple pressure systems and sealing of complex formations.A kind of integral,high pressure resistant FF-level gas wellhead and ground safety linkage device was developed to accomplish safe and environmentally friendly gas production. | GUO Xusheng HU Dongfeng LI Yuping DUAN Jinbao JI Chunhui DUAN Hua | 2018 | Petroleum Exploration and Development2018，45，1： | 0 |
| 10 | 基于地震相分析的碳酸盐岩渗透率预测显示文摘储层渗透率的预测一直是油田勘探的难点,但是其非均一性直接影响油田的生产,原因在于其油藏形成、构造及地层矿物等属性各异造成了勘探区域内渗透率的横向分布不稳定,对渗透率进行预测就需要找到一个合理的约束条件。由于渗透率受沉积环境的影响明显,因此可以将沉积相划分作为约束条件,利用STRATA地震相分析软件结合地质资料、测井资料以及岩芯资料将沉积相和地震相建立对应关系,而后通过测井资料、岩芯资料搭建纵波阻抗和渗透率的拟合关系对渗透率进行合理的刻画,针对各个地震相进行渗透率预测。由于这种方法建立在横向的地质解释基础上,因此能够结合地质资料进行更精确的横向预测。 | 赵荣坤 文晓涛 蒲勇 | 2014 | 重庆科技学院学报(自然科学版)2014，16，1： | 0 |
