摘要
勃海湾BZ3-1-2丛式井导骨架中最后完钻的井.在深部小井眼及井针<2. 90的情况下扭方位1600成功。该井离邻井很近,用Mw}系统排除了邻井套管的从干扰,控制方位准确到达靶区。
In the finally completed borehole in the conductor casing rack of BZ 3}一2 cluster well in BohaiBaY。turning the direction of I 600 has met with success in the case of a small hole in deep and a devia-tion<2. 90. This well is very close to the neighbour wells. Through eliminating magnetism disturbancefrom the c,3sing in neighbour wells by MWD system.its direction was controlled and the borehole accu-rately reached to the target area.
