RICH油藏描述软件在低孔低渗油气藏中的储层预测应用研究

APPLICATION STUDY ON THE RICH RESERVOIR DESCRIPTION SOFTWARE IN THE PREDICTION OF ESERVOIR WITH LOW POROSITY AND PERMEABILITY

针对低孔低渗油气藏的岩性、物性、储集空间及储集类型等方面的特点,认为 RICH油藏描述软件的基于信息融合理论的地震岩性反演技术、空间油气模式识别技术、储层岩性解释技术能有效地解决此类油气藏的储层预测问题。本文首先重点介绍了这几项特色技术的基本原理,然后并以四川中部一个低孔低渗油气藏区块的攻关实验为例,介绍了该软件应用于此类油气藏储层预测研究的方法和应用效果。

According to the lithology, physical property, space and type of the oil or gas reservoirs with low porosity and permeability, RICH , which is based on the seismic lithology inversion technology of the information blending theory, space oil-gas patten recognition technique and reservoir lithology interpretation technology, is considered to be able to solve this kind of reservoir prediction problems. This paper first introduces the basic principles of this technology, and then taking a oil-gas reservoir block with low porosity and permeability in the middle part of Sichuan as an example. It also introduces the research approaches and application effects of this software in reservoir prediction.
