南海西部海域最早开始在A油田的开发调整井中采用随钻测井技术作为地质导向,随后在北部湾、莺歌海、珠江口等盆地的油气田开发中使用了随钻测井技术,获得了大量的随钻测井资料。随着该项技术的日益成熟,2007年首次在北部湾盆地的探井中采用LWD技术。为了评价该项技术在南海西部的应用效果,通过对上述盆地随钻测井资料和电缆测井资料的对比,总结出LWD资料的优缺点,逐步阐述了随钻测井技术在本地区的发展历程,进而说明如何通过对该项技术的跟踪分析,促成其从简单应用于地质导向逐渐进入探井、评价井作业中。研究结果表明LWD技术在南海西部海域取得了令人满意的效果。

Logging while drilling technique(LWD)was first used for geosteering in an oil field of west South China Sea.Then,substantive LWD information was obtained by its appliance in the development of Beibuwan,Yinggehai,and Zhujiangkou basins.In 2007,with the mature of the technique,it was used first in Beibuwan basin exploration well drilling.Information of LWD and wireline logging was compared to evaluate the application effect of LWD.Pros and cons of LWD were generalized and further the way of how to promote it from simple geosteering to deep application to exploration and appraisal well operation and by trace and analyses was illustrated.Research results show that application effect of LWD is satisfying.
