摘要
乌夏断裂带下部二叠系地层具有地层倾角大、坚硬、可钻性差等地质特点。针对该地区下部地层易井斜、钻速低的特点,施工过程中应用了大钻压、复合钻井、水力加压器等防斜打快技术,取得了显著的效果。
Permian layer under Wuxia fracture belt has characteristics of higher formation dip which supreme dip angle is 60 degree, solider, the drill ability of layer is relatively bad and so on in Wuxia fracture belt. According to the features of the lower formation with well deviation easily and lower drilling rate, so we employ the technology for anti-deviation and fast drilling about great bit weight, combine of bore well, Hydraulic thruster and so on, and obtain the obvious of effectiveness.
