中原油田与华东石油学院钻井教研室合作,开展了d_c指数随钻监测地层压力的研究工作。对文留地区的115口井进行了d_c指数监测,选用其中48口并的单井趋势线方程,做出了文留地区d_c指数监测地层压力透量板。经现场试验,效果良好,并已投入现场使用。 Zhongyuan Oilfield and East China Petroleum Institute of Drilling Department in cooperation with the d_c index to monitor the formation pressure while drilling work. The d_c index of 115 wells in Wenliu area was monitored and 48 single well trendline equations were selected to make the pressure permeability plate of d_c index monitoring in Wenliu area. The field test, the effect is good, and has been put into the field.
