神木双山区块主要指榆林周边的区域。神木双山区块气井水平井与苏里格气井相比具有延安上部地层易缩径,延长下部和纸坊上部地层易垮塌,纸坊和刘家沟地层易造浆,刘家沟地层承压能力低易漏失的地层特点,针对这些特点与难点推出了相对应的一套技术方案和措施,结合实际应用出现了一些问题,总结了经验,改善了措施,完善了神木区块的钻井液技术。 Shenmu Shuangshan block mainly refers to the area around Yulin. Compared with the Sulige gas well, the Shuimingshan Shuangshan block gas well has the features of easy shrinkage in the upper strata of Yan’an, easy collapse of the lower part of the Shuiminshan block and the upper part of the paper mill, easy formation of pulp in the paper mill and Liujiagou formation, and pressure bearing capacity of the Liujiagou formation Low loss of strata characteristics, in response to these characteristics and difficulties introduced a set of technical programs and measures, combined with the practical application of some problems, summed up the experience and improve the measures to improve the Shenmu block drilling fluid technology.
