摘要: 在用自然电位或微电极测井曲线标定泥岩段的基础上,利用声波测井数据预测地层孔隙压力,并以樊ll-l井为例进行计算。博兴地区压力总体上北高南低,存在纯化隆起和洼陷中心大芦湖地区两个压力高值区、青城凸起和南部缓坡两个压力低值区,压力分布与油气运移之间存在着一定的相关性。据此推测,压力是影响该区油气运移的最主要的动力之一。

Abstract: The method of predicting formation pressure using sonie logging data is presented. The self potential and micro electric logs are used to calibrate the shale interval in F1I Well of Dongying sag. From the pressure profile dist ribution plot and top interface pressure dis-(tribation plot of Es3, Boxing region is of high pressure in north and low pressure in south. Two high pressure areas are located in Chunhua uplift and Dahulu subsag compared with two low pressure areas in Qingcheng swell and south slope. It is believed that cerlain correlations seem to have between the pressure distributions and hydrocarbon migration and distribution. That is, oil and gas always migrate from high pressure area toward low pressure area. So pressure is one of the most important powers for petroleum mi gration in this region.

Key words: Dongying sag, Boxing, fonnation pressure, interval transit time
