摘要
保德地区位于鄂尔多斯盆地东缘北部,属于山西西部褶皱带的北部,保德区块属于中低阶煤层气田,钻井工作量大,煤层气发育,主力煤层8+9#煤层裂缝发育,易造成卡钻事故。通过对保德区块无线随钻定向测量、钻头选型、钻具组合、钻井液性能和施工工艺等方面展开研究,总结出适合保德区块的丛式井无线随钻测量快速钻井施工工艺。
The Baode area is situated in the north part of Ordos Basin eastern margin,belongs to north part of western Shanxi folded belt.The Baode block is a medium to low ranked coal CBM field with large amount of drilling and well developed CBM.Its main coal seam No.8+9 has well developed fissures,thus easy to cause sticking of drilling tools.Through study on aspects of wireless directional MWD,bit selection,drilling tools assemblage,drilling fluid performance and operation technology have summed up a cluster wells wireless MWD rapid drilling operation technology propitious to Baode block.
