应用有限单元法预测碳酸盐岩裂缝发育区带

Forecasting Fracture Zone of Carbonate Rock by Using Finite Element Method

本文介绍了有限单元法的基本原理和计算方法,提出用此法计算地质历史时期构造应力场的一般步骤,举例说明构造应力场对碳酸盐岩中裂缝发育的影响,分析了该法预测裂缝的效果,为合理勘探裂缝性气藏提供一种新的研究手段。

In this paper, the basic principle and computation of finite element method is described, the general procedure in computing structure stress field in the historical period of geology is put forward, by using the method, the result of forecasting fracture is analysed, and the effect of structure stress field on frac- ture growth of carbonate rock is illustrated by example to provide a new study medium for reasonably explorating fractured gas reservoirs.
