摘要
苏里格气田为低孔低渗低丰度大型气田,为提高单井产量达到产能规划目标,采用水平井技术对苏里格气田进行整体开发势在必行,而砂体钻遇率是水平井单井产量高低的关键因素。根据前期综合地质研究成果,运用水平井地质导向技术,结合随钻测井曲线预测砂体走势并及时调整钻进轨迹,大幅提高了砂体钻遇率,使水平井产量达到了直井的3倍~5倍,取得了良好的效果。
Sulige gasfield is a large-scale one with low porosity,low permeability and low abundance.To increase the single-well production and then reach the target productivity,horizontal-well technology must be adopted for overall development.Drilling ratio of sandbody is the key factor of single-well production.According to some achievements obtained from comprehensive geological research,using geo-steering technology of horizontal well,predicting sandbody trend by well-logging curve while drilling and adjusting well trajectory,this study increases greatly drilling ratio of sandbody.The yield of horizontal well reaches 3 to 5 times of vertical one's.
