1Prediction of casing wear in extended-reach drilling显示文摘Intermediate casings in the build sections are subject to severe wear in extended-reach drilling. This paper presents a new method for predicting the depth of a wear groove on the intermediate casing. According to energy principle and dynamic accumulation of casing wear by tool joints, a model is established to calculate the wear area on the inner wall of the casing. The relationship functions between the wear groove depth and area are obtained based on the geometry relationship between the drillstring and the wear section and the assumption that the casing wear groove is crescent-shaped. The change of casing wear groove depth versus drilling footage under different-sized drillstrings is also discussed. A mechanical model is proposed for predicting casing wear location, which is based on the well trajectory and drillstring movement. The casing wear groove depth of a planned well is predicted with inversion of the casing wear factor from the drilled well and necessarily revised to improve the prediction accuracy for differences between the drilled well and the planned well. The method for predicting casing wear in extended-reach drilling is verified through actual case study. The effect of drillstring size on casing wear should be taken into account in casing wear prediction.Gao Deli Sun Lianzhong Lian Jihong 2010Petroleum Science2010,7,4:18
2Carboxylesterases in lipid metabolism: From mouse to human显示文摘哺乳动物的 carboxylesterases 水解大量 xenobiotic 和内长的混合物,包括类脂化合物酉旨。在类脂化合物新陈代谢的 carboxylesterases 和在 vivo 的精力动态平衡的生理的函数被基因操作和化学抑制在鼠标,并且在 vitro 表明了通过(在上) 表达式,表达式击倒、化学在许多房间的抑制。最近的研究进展揭示了 carboxylesterases 的关联到象肥胖那样的新陈代谢的疾病和脂肪肝疾病,建议这些酶可能是为新陈代谢的混乱的处理的潜在的目标。以便翻译现出症状之前的潜的研究在细胞并且到在老鼠之间的 carboxylesterases 的人和人的老鼠模型需要被阐明。这评论在鼠标和人的结构和功能介绍并且讨论研究进步在类脂化合物新陈代谢和新陈代谢的混乱的这些酶的 carboxylesterases,和角色。Jihong Lian Randal Nelson Richard Lehner 2018Protein & Cell2018,9,2:6
