摘要

包括石油和天然气在内的矿床地质力学监测的目的是控制岩体的状态,预测油田生命周期各个阶段可能出现的风险和并发症:储层和盖层完整性破坏、钻井和完井系统完整性破坏、基础设施设施破坏。本文提出了在储层和目标层段开发过程中,基于地表(或海底)位移和变形观测的地质力学监测系统的组织方法。考虑到弹性强度特性的非均质性,在考虑孔隙压力变化的简单模型上已经测试了解析和数值方法。

Solving the Inverse Problem of Geomechanical Monitoring to Improve the Efficiency of Field Development
The purpose of geomechanical monitoring at mineral deposits, including oil and gas, is to control the state of the rock mass, forecast possible risks and complications at all stages of the field's life: reservoir and caprock integrity failure, violation of the integrity of drilling and system of well completion, infrastructure facilities. The paper suggests approaches to the organization of a geomechanical monitoring system based on observations of displacements and deformations of the ground surface (or seafloor) during the development of reservoir and target interval. There are analytical and numerical approaches have been tested on simple models with pore pressure changes, considering the heterogeneity of elastic-strength properties.
