从世界部分产油国提高采收率的措施看地球物理技术发展

Regard the development of geophysical techniques from EOR methods of some oil producing countries

统计分析世界部分产油国家提高石油采收率的增产措施的发展趋势 :热采是目前提高采收率的主要方法 ,注CO2 增产的方法发展最快 ,而注聚合物的方法在国外已经逐渐淘汰。根据这些情况 ,地球物理技术的发展要考虑适当提高下井仪器的温度性能指标 ,加强地层孔隙中流体成分和性质的研究 ,尤其是在地层温度。

Statistical analysis shows that the trend of EOR in some oil producing countries is like this: thermal recovery is the major EOR method, CO 2 stimulation is growing most rapidly, and polymer injection is gradually eliminated. So that, temperature performance index of downhole instrument should be improved. The study of fluid composition and property in formation pore should be enhanced, especially the study of physical property and geophysical response of pore fluid under formation temperature and pressure.
