声学测井技术在石油工程中的应用探索

Applied exploration of acoustic logging in petroleum engineering

当前油气勘探的目标与对象所面临的难点突出表现在储层的复杂与埋深的增大,钻井与储层改造难度的增加。缩短钻井周期、提高测试与压裂成功率、加快勘探节奏已成为关注的焦点。同时对测井技术在此领域中发挥的作用提出了新的需求。文章介绍了以偶极声波为主的声学测井技术在钻井过程井眼稳定性评价、储层压裂改造施工设计、效果检测等石油工程方面的应用及技术优势,展现了测井技术在该领域良好的应用前景。

Currently,the goals and difficulties of oil and gas exploration lie in the increasing complexity and depth of reservoir, and the increased the difficulty of drilling and reservoir stimulation.Reducing drilling cycle,enhancing success rate of testing and fracturing,and speeding up the pace of exploration have become the focus of attention.Simultaneously logging in this area has been proposed new requirements.This paper introduces the application of petroleum engineering and technological advantages of the dipole acoustic logging technology-based acoustic logging in evaluation of borehole stability during drilling and construction design of the reservoir fracturing.Good prospects of logging technology in this field are shown.
