摘要: 川东南地区是我国页岩气勘探开发的前沿阵地,区内井网控制程度低、井震矛盾突出、岩屑代表性差,且钻探的水平井水平段长,给地质导向工作带来较大困难。针对上述难点,利用“三步骤”地质导向方法,对川东南页岩气勘探水平井A井进行了地质导向。首先,基于区域地质资料和导眼井测井曲线特征,确定了地层对比标志层,为实钻过程中的地层对比工作提供依据;在入靶前地质导向阶段,进行曲线微观特征对比,结合录井气测资料识别标志层,预测A靶点深度,并调整轨迹,确保该井顺利中靶;在水平段地质导向阶段,密切观察随钻自然伽马曲线的变化趋势,准确判断钻头位置,并利用标志层控制轨迹,确保钻井轨迹始终位于靶窗内。该井水平段钻遇优质页岩储层1 317m,优质储层钻遇率达100%,取得了显著的效果。现场应用实践表明,该地质导向技术适用于川东南地区页岩气水平井钻井,能够有效提高优质页岩储层钻遇率,对国内其他页岩气区块的地质导向工作具有较好的借鉴意义。

Abstract: Southeast Sichuan has been at the forefront of shale gas exploration and production of China.However,problems such as relatively scarce well data,obvious contradiction between logging and seismic data,poor representativeness of cuttings,and longer horizontal section,have made it difficult to do geosteering drilling.Aimed at the difficulties,geosteering of exploratory Well A for shale gas has been executed by the geosteering method of three steps.First,based on regional geological data and logging curve characteristics of guide hole well,marker beds were determined,which provided a basis for correlation of strata while drilling.In geosteering stage before A target,combined with gas logging data,micro-characteristics of logging curve were analyzed to identify the maker beds,and the drilling track was adjusted according to the predicted depth of A target,to ensure precise target hitting.In the geosteering stage for the horizontal section,the variation trend of GR curve while drilling was analyzed,and the bit location was determined.The drilling track was controlled in target window by marker beds.Finally,the length of high quality shale of horizontal section is 1 317m,the drilling ratio was 100%,and the effect was remarkable.The geosteering technology is suitable for shale gas horizontal well drilling in southeast Sichuan,and can effectively improve the drilling ratio of high quality shale,and has high reference value to geosteering of other domestic shale gasfield.
