摘要(Abstract)：

在裂缝性油藏开发过程中,由于油藏严重非均质性,注水开发效果并不理想,可采用气驱方式开采。根据物质守恒原理,考虑裂缝和孔隙两套系统、注入气在原油中发生部分溶解以及原油与注入气混合物变化3种因素,建立了裂缝—孔隙型的注气物质平衡新方程。研究表明,在基质系统和裂缝系统中,同时考虑原油和注入气形成的混合物,采用膨胀实验将气油比进行量化,建立的注气模型更能反映实际的裂缝油藏注气过程。通过X油藏注气实例分析,建立的物质平衡新方程可准确拟合注气开发油藏基质储量和裂缝储量,其误差仅为1. 5%,可为注气开发裂缝—孔隙型油藏提供可靠的理论依据。
In the process of the development of fractured oil reservoirs,due to the serious heterogeneity of the reservoir,the water flooding effects is not so ideal,so the way of gas drive is adopted to exploit these reservoirs. According to the principle of the material balance,considering three factors i. e. two sets of the systems( fracture and pore),the injected gas occurs partly dissolved in the oil and the mixture changes of the crude oil and injected gas,a new fractured-porous-type material balance equation for the gas injection was established. The achievements show that in the matrix and fracture systems,the mixture of the crude oil and the injected gas was taken into account simultaneously,the gas-oil ratio was quantified by the expansion test,the established gas-injecting model can reflect the actual gas injection process of the fractured oil reservoir. With the help of the gas-injection case analyses in Oil Reservoir X,the established new balance equation can accurately match the reserves of both the matrix and the fracture of the gas injected oil reservoirs; the error is only 1. 5%. So the equation can provide reliable theoretical foundation for the gas injected fractured-porous-type oil reservoirs.
