摘要
通过分析山西L型煤层气水平井的技术难点,在此基础上探寻相应的技术对策,着重建立造斜着陆与水平段导向两大导向模型,形成了以标志层划分与对比、地层倾角推算、地质建模和实时轨迹控制4个方面为主的L型煤层气水平井地质导向技术流程。该技术在T-P05井的成功应用,不仅丰富了煤层气水平井地质导向技术的内容与方法,更进一步验证了该技术在现场具有较强的可操作性和良好的应用前景,值得在山西临汾区块的L型煤层气水平井施工中大力推广与应用。
Based on the analysis on the technical difficulties of L-type CBM horizontal wells in Shanxi,the corresponding technical countermeasures are explored,2 build-up guidance models of landing and horizontal sections are established to form the geo-steering technical process mainly in 4 aspects of marker beds division and correlation,stratigraphic dip calculation,geological modeling and real-time trajectory control for L-type CBM horizontal wells.The successful application of this technology in T-P05 well not only enriched the contents and methods of geo-steering technology for CBM horizontal wells,but also further verify its good feasibility and application prospect,this technology is worth promoting and applying in L-type CBM horizontal wells in Linfen block.
