超稠油油藏火驱开发物理模拟实验研究

Experimental Research on Physical Simulation of Fire Flooding in Extra-heavy Oil Reservoir

针对辽河油田的超稠油开发方式问题,采用火烧油层一维模拟装置,对曙1-38-330井的脱水原油进行物理模拟实验。根据实验结果,分析了火驱前后原油的物理化学性质、注采压差、火驱尾气成分、燃烧基础参数等,认为在曙1-38-32区块的超稠油油藏开发中,采用火驱法提高采收率是可行的。

In order to study the development mode of extra-heavy oil reservoir,in-situ combustion physical simulation experiments are used to exploit dehydrated crude oil in Shu1-38-330 well,Liaohe Oilfield.The experiment analyzes the physicochemical properties of oil,variation of injection-production pressure,composition of fire flooding emission and combustion parameters;the analysis results show that,it is feasible to exploit extra-heavy oil reservoir by in-situ combustion in Shu1-38-32 block.
