摘要
川中地区磨溪构造T1J2白云岩储层存在岩性复杂、产层渗透率低、储层物性变化大等特点,储层识别困难,给工区产层地质导向钻井造成了很大的风险。利用随钻测井资料,提取其中与储层类别关系密切的参数,建立了工区导向目的层的随钻储层类别识别模式。采用灰色关联法编制了处理程序,对工区Mo005-H6井用随钻测井资料识别储层。应用结果表明该方法能够及时准确地对工区复杂白云岩储层进行识别,为产层导向钻井井眼轨迹沿储层有利部位穿行提供了可靠依据。
It is difficult to do reservoir recognition in the T1J2 dolomite reservoir of Moxi in central Sichuan province for its complex lithology, low permeability of pay zone and great physical property change, which creates large hazard to the geosteering drilling of pay zone. A reservoir recognition mode of the geosteering zone is established by extracting reservoir classification parameters from the LWD data. Data processing programme, which is based on grey correlation analysis, is used to do reservoir recognition in drilling Mo005-H6 well. The recognition result shows that this method could identify the complex dolomite reservoir in the surveyed area immediately and accurately, and guide the geosteering drilling along the beneficial pay zone.
