什么叫水平井?概括而言就是,井斜角达到或接近90°,井身沿着水平方向钻井一定的长度的井。近年来随着水平井数量的逐渐增加,水平井技术的不断完善,随钻已经成为大斜度井、水平井和小井眼侧钻多分支井油藏评价的重要手段。目前,水平井测井资料处理解释研究的重点主要集中在三个方面:一是大斜度井与水平井的测井仪器响应,通过数值模拟技术研究各种影响因素对电阻率(双侧向、感应和电磁波)测井仪器响应,制作解释图版。二是各向异性的实验研究主要集中在岩石的各向异性测量和测井资料的各向异性校正方面。三是测井资料处理解释软件的开发。
What is a horizontal well? In a nutshell, a well with a well angle at or near 90 ° drills a length of well along the horizontal. In recent years, along with the gradual increase of the number of horizontal wells and the continuous improvement of horizontal well technology, the LWD has become an important method for evaluating multi-branch well reservoirs with side-drilled multilateral wells in high-deviated wells, horizontal wells and slim-hole wells. At present, the research of horizontal well log data processing and interpretation mainly focuses on three aspects: First, the response of logging tools of high-deviated well and horizontal well, and the effects of various influencing factors on the resistivity , Induction, and Electromagnetic Wave) Logging Tool Response, Making Interpretation Plate. Second, the experimental research on anisotropy mainly focuses on the anisotropy of rock and anisotropy of logging data. Third, the interpretation of logging data processing software development.
