利用储层物性参数预测油气

储层物性参数处理技术是根据双相介质理论,使用地震、地质数据提取储层的孔隙度、密度、层速度、视渗透率、流体密度等物性参数的一种处理方法.这些物性参数剖面比常规地震剖面更细致地反映了地下各种地质现象,揭示地质体的岩性变化及油气聚集规律.多年来该技术已在海上、陆上许多油田使用,并得到完善和发展.文中重点介绍在南海北部不同沉积盆地应用该技术进行油气预测的实例及认识.

HYDROCABON PREDICTION USING PETROPHYSICAL PARAMETERS OF RESERVOIR

The technique for estimating the petrophysical parametsre of reservoir is based on two-phase medium theory. The setimated petrophysical parameters sections used seismic data and geologic data are more meticulous than conventional seismic sections,on which the lithologic variation and hydrocarbon accumulation features con be seen. By used long time,the method has been tested,used,and developed in many part-s, and obtained results under different geologic conditions. Authors present several typical examples to show the hydrocarbon prediction using petrophysical parameters in western of South China Sea, which help both on the exploration and development.
