地应力分析在老新地区油田开发中的应用

On Application of Earth Stress Analysis in Oilfield Development of Laoxin Area

地应力是油气运移、聚集的动力之一.地应力作用引起的储层裂缝、断层及构造是油气运移、聚集的通道和场所。采用测井、岩心和地震资料,运用无源微地震法、地层倾角法、油藏动态法和综合裂缝储层描述软件对老新地区地应力进行深入分析,能够为油田开发方案部署、注采井网优化调整提供科学依据。

Earth stress is one of dynamic forces of hydrocarbon migration and accumulation. Reservoir factures, faults and structures induced by earth stress effect are the channels and places of hydrocarbon migration and accumulation. The earth stress analysis by means of sourceless fine seismic motion, strata dip, dynamic reservoirs and integrated description software of facture reservoirs with the help of logging, core and seismic data in Laoxin Area provides some scientific foundations about injection-production pattern arrangement and optimizing adjustment of development program so as to improve the oilfield development effect.
