冀东油田地层压力评价技术研究

根据测井、井史、试油及地层测试等资料的分析结果，利用声波时差法、ｄｃ指数法和页岩电阻率法，综合评价了冀东油田柳赞地区和高尚堡地区地层孔隙压力情况。对比分析表明，在该地区利用声波时差法和伊顿公式法检测地层孔隙压力具有较高的精度。给出了以上两地区的地层孔隙压力剖面以及近平衡压力钻井泥浆密度推荐值。

Study on Pore Pressure Evluation for Jidong Oilfield

In this paper,a comprehensive evaluation on pore pressure for Gaoshangbu area and Liuzan area of Jidong Oilfield was carried out using sonic approach, dc exponent approach and shale resistance approach on the basis of analyzing logging data,well history data,formation testing data and RFT data.The study shows that the excellent prediction results on pore pressure can be obtained by using sonic approach and Eaton's Equation in this two areas.The pore pressure curve and recommended drilling fluid density suitable for this two areas were given.
