全压力史拟合在现代试井解释中的应用

Application of the Fitting in the Whole History Pressure in Modern Well Test Interpretation

现代试井解释中常遇到解释模型多解性问题,不同的储层类型、边界类型,有时表现出类似的压力特征,特别是在边界性质的判断上,选择正确的边界类型困难较大。利用全压力史拟合方法,对海上某深层湖相碳酸盐岩油田A9井储层边界类型进行判断,取得了较好效果。

In the modern interpretation of well test,problem of multi-solution to interpretation model is frequently encountered.For different reservoir types,boundary type,and sometimes the pressure on the performance of similar characteristics,in particular,determining the nature of the border,it is difficult to select the correct type of boundary.By using method of the fitting in the whole history pressure and determining the type of boundary of the deep sea oil fields A9 lacustrine carbonate reservoir wells,good results are achieved.
