摘要
双重孔隙介质油藏的研究主要集中在定产量开采条件下的不稳定压力分析,对定压开采条件下的不稳定产量分析研究得较少。通过对双重孔隙介质油藏的数学模型进行拉普拉斯变换得到了其在两种边界条件下的拉氏空间的解,再分别对其进行数值反演得到了实际空间的解。再把这些理论公式用VB6.0编制成计算机程序,接着把程序运算得到的数据导入到EXCEL中,在EXCEL中绘出了许多理论曲线和图版。
At present,the research of dual pore medium reservoir mainly concentrates on unsteady pressure analysis under the condition of constant production,but the unsteady production analysis under the condition of constant pressure is rarely studied.The latter in detail is studied.Firstly,Laplace solutions of two boundary conditions is obtained through Laplace transform for the mathematic model of dual pore medium reservoir.Then real space solution is obtained by the inverse Laplace transform.Then these theoretical formulas are designed in a program with VB6.0,next.Type curves are plotted with the results of above program in EXCEL.
