- And the second level branch was then sidetrack drilled through the suspension open hole in the first lateral well. 在斜向器回收未成功的情况下,采用绕障钻通主导眼实现压力连通。
- Since 1995,sidetracking operations have been conducted in Zhongyuan Oilfield,and a set of perfect slim hole sidetracking technology has been formed. 中原油田自1995年以来开始进行了老井开窗侧钻小眼井技术，数年的努力形成了一套完善工艺。
- But in deep well drilling practices of long open hole,the homogeneous gns generally invades borehole. 但在一些长裸眼段深井的钻井实践中，常常会遇到均匀气侵溢流。
- Index 16, a wide dogleg right opening hole to warm up. 难度16，开波俾条又阔又短既右狗腿等你松下身，小心果岭边沙池。
- The next thing I knew I was married and riding a Schlumberger logging unit in Natchez, MS as a open hole (FES) Field Engineer. 而后来发生的事情就是我结了婚,并当上了一名开孔现场工程师(FES),在位于MS的Natchez操纵Schlumberger的测井拖橇。
- The well logging testing shows that measurements made with CHFR tool are very well matching with open hole resistivity in a new cased hole. 试验结果表明,在新完钻且未射孔生产的套管井中,CHFR测量的地层电阻率与其裸眼井测井电阻率有着较好的一致性;
- The improved performance of anticorrosion was resulted from the increase of coating density, the decrease of open hole percentage and pylome numbers. 这是由于纳米掺杂使涂层密度提高，开孔率、通孔率降低，组织均匀性提高所致。
- Existing plural pressure system in the same open hole not only brings troubles to drilling operations but also makes cementing much more difficult. 在同一裸眼段出现多套压力层系,不但给钻井作业带来很大的困难,而且大大增加了固井作业的难度。
- With the comparison to open hole electric resistivity,depletion index is used to qualitatively evaluate the water flooded degree of oil layers. 通过与裸眼井电阻率对比,利用衰竭指数定性评价油层水淹程度。
- The extended reach well has such chara cteristics as large horizontal displacement,great deviation angle and long open hole interval. 大位移井具有长水平位移、大井斜角以及长裸眼段的特点。大位移井钻井过程中摩阻扭矩的预测和控制是成功地钻成大位移井的关键因素之一。
- Aciding and perforatin are not effective for eliminating solids damage in acid-sensitive formation or well with open hole completion. 对于酸敏储层和裸眼完井的井,不能采用酸化和射孔方法清除滤饼和消除固相损害。
