任11碳酸盐岩油藏注CO2提高采收率研究
Study on EOR by carbon Dioxide Injection Process in R11 Carbonate Reservoir
摘要
Abstract
Many carbonate reservoir have been into high water-cut development stage. How to dig the remaining oil potential and enhancing oil recovery further is dominant work target now. There are many problems in carbonate reservoir of Rl 1, such as low oil production of single well, inefficient utilization of injected water, and worsening of the water-flood efficiency. Therefore it is necessary to find a new way to dig reservoir production potential. The EOR mechanism by Carbon dioxide injection process in Rl 1 is analyzed and the numerical simulation research on EQR by Carbon dioxide injection process in Rl 1 reservoir is completed. Aimed at reservoir properties and development characteristic the three-dimensional numerical model is setup. Based on the fitting history of water flooding, the gas injection rate, gas injection mode, gas injection position and the gas-oil ratio control are optimized. The plan of Carbon dioxide injection is predicted for 20 years and the result shows that oil production rise obviously and it can enhance oil recovery about 3.5% more than the current exploitation mode.关键词
