ANALYTICAL SOLUTION OF FLOW IN INFINITE STRATIFIED OIL RESERVOIR AND ITS APPLICATION

This paper presents an analytical solution for the production function and pressure distribution function of flow in infinite stratified oil reservoir with crosflow under the condition of constant wellbore pressure (CWP condition) by Weber's integral transformation. The calculation results are shown in the form of curves and these results can be used to analyse unsteady flow test of production with CWP condition.

Application of Attributes Fusion Technology in Prediction of Deep Reservoirs in Paleogene of Bohai Sea

1 Introduction The Paleogene strata(with a depth of more than 2500m)in the Bohai sea is complex(Xu Changgui,2006),the reservoir buried deeply,the reservoir prediction is difficult(LAI Weicheng,XU Changgui,2012),and more

敏感性油藏油层保护技术的研究与应用

针对龙南油田滚动开发过程中暴露出油井热洗后产量下降幅度大、水井注水压力上升快、注水难度大的矛盾,开展了油层保护技术研究。以渗透率伤害率为目标,筛选保护液类型;通过多项实验对比分析,筛选最优施工工艺。并在滚动开发实践中加以应用,取得了一些认识,对同类低渗透敏感性油藏高效开发具有一定的经验借鉴。
