摘要:
通过压力恢复数据及储层岩石特性，建立符合高探1井地层真实状况的双孔介质部分射开“U”形边界数学模型，采用Laplace变换及分离变量法对数学模型进行求解，利用Stechfest数值反演绘制出压力及其导数双对数试井曲线，对高探1井压力恢复资料进行解释分析；采用瞬时IPR曲线预测产能，采油指数高达2273 m3/(d  ·MPa)。结果表明，高探1井储层物性好，压力高，污染小，具备高产且长期稳产的能力。高探1井在试油期间录取的大量动态数据，可为油气开发制度的制定提供可靠依据。
Abstract:
Based on the pressure recovery data and rock characteristics of the reservoir, a mathematical model of the dualpore medium in accordance with the real conditions of the Well Gaotan 1 was established, which partially penetrated the formation with a Ushaped boundary. Solve the mathematical model with Laplace transform and variable separation method. Double logarithmic well testing curves of pressure and its derivative were drawn by Stechfest numerical inversion. And the pressure buildup data of Well Gaotan 1 was 〖JP2〗interpreted and analyzed. Predict productivity using instantaneous IPR curve, with oil production index as high as 2273 m3/(d  ·MPa).    The results show that the reservoir physical properties of Well Gaotan 1 are good with high pressure and small pollution. And the reservoir has a high productivity for longterm and stable production. The large amount of dynamic data collected during the oil testing of Well Gaotan 1 can provide a reliable basis for the formulation of oil and gas development systems.
