摘要

压力预测技术主要是应用了地震层速度计算出地层孔隙压力及压力系数 ,据此 ,设计出钻井液密度 ,从而实现近平衡钻进 ;同时 ,根据层速度与深度的交会关系 ,确定低速高压异常带 ,则可判断油气层的位置。中原油田自 1 988年应用压力预测技术以来 ,已预测了 1 2 0口重点探井及开发调整井 ,实现了近平衡钻井及钻前油气预测 ,节约了大量钻井成本 ,防止了井喷、井涌等钻井事故 ,防止了油气层污染 ,保护了油气的顺利开采
The technique of pressure prediction is mainly to calculate formation pore pressure and pressure coefficient with seismic interval velocity,and based on it,reasonable density of drilling fluid is designed, thus nearly balanced drilling is realized At the same time,a low velocity and abnormal high pressure zone is determined to discriminate the position of oil and gas formation based on the relationship of intersection The technique has been used in Zhongyuan oilfield since 1988,120 of major exploration wells and adjustment wells are predicted,oil and gas predictions of nearly balanced drilling and pre drilling are realized,by which large number of drilling costs are saved,drilling accidents of blowout and well kick and reservoir pollution are prevented,thus smooth production is guaranteed
