油、气田储量估计的试井分析方法

ESTIMATING THE STORAGE CAPACITY OF OIL/GAS RESERVOIRS BY WELL-TEST ANALYSIS

本文在对油、气田储层的几何结构及钻井位置不做任何假定下，对无流动边界和定压边界两种情形给出油、气田储量估计的试井公式。用本文方法估计储量仅需要少量地质资料和试井数据，特别适宜于在探井阶段提供储量评估。

In this paper, we present two well-test formulae for estimating the storage capacity of oil/gas reservoirs. One formula has impermeable boundary conditions and the other has constant-pressure boundary conditions. The method used in this paper is applicable to both two and three dimensional reservoirs. There are no restriction on the geometry of the oil/gas field or the location of the wells. In particular, the method does not require a long period of the historical exploitation data of the reservoirs, therefore it is suitable for providing an estimation of storage capacity in the exploration stage.
