Abstract


Zhongyuan Oilfield \The current chemical flooding, microbial enhanced oil recovery technology can only meet the reservoir temperature less than 90 ℃, salinity 10 × 10 4 mg / L below the reservoir, the application range is greatly restricted, unable to meet Zhongyuan Oilfield harsh reservoir conditions. In addition, more than one third of Zhongyuan Oilfield geological reserves of permeability of less than 50 × 10 -3 um 2 of low and ultra low permeability reservoirs, this part of the current water reserves technology can not meet the development requirements, mainly rely on natural energy development, recovery can only reach 15 to 20%, poor development effect. How to develop a deep low and ultra low permeability oil reservoirs are both facing a big problem as well as oilfield production yield opportunities and challenges to improve the development of this part of the reserve effect on oil yield and stable yield has very important significance. Currently there are about more than 700 ports Zhongyuan Oilfield natural energy efficiency wells and water injection wells are not covering the geological reserves of more than 6,000 tons, the low level of recovery of these wells (8 to 9%), is CO 2 single well throughput of choice, is the future yield, and production potential. After years of research scientists and national experts assessment that CO 2 throughput, miscible flooding is to improve the main direction of Zhongyuan oil recovery. CO 2 single well stimulation because less investment and quick and can to a certain extent reflect the CO 2 drive on the adaptability of the reservoir, it is necessary to carry out the technology research work, and for the subsequent CO 2 -drive technical preparedness. Refer abroad CO 2 single well stimulation wells election conditions, combined with the Zhongyuan oilfield reservoir characteristics, selected Wenliu different crude oil physical properties four wells studied, hoping for selected wells conduct laboratory experiments and numerical reservoir simulation studies to understand the Zhongyuan oilfield reservoir for CO 2 single well stimulation mechanism and the main production of the main factors affecting yield in order to better guide the technology in the Central Plains oilfield application. Through four wells on the selected oil samples for indoor gas injection swelling test and multi-level degassing pilot study showed that CO 2 single well stimulation mechanism of the main production: With the injection of CO 2 mole percent increase in injection pressure increased, the formation of oil and gas-oil ratio changed significantly, especially after gas injection solution gas-oil ratio increased significantly, oil formation volume expansion significantly, the proportion of crude oil, the viscosity significantly reduced, increases the flow of crude oil capacity, to improve oil production is extremely beneficial; through the use of CMG component model to optimize the design of injection solutions, indicating that CO 2 injection volume, injection rate, oil wells boring time, production there is an optimal value speed, etc., the need to optimize the design of the program, in order to obtain the best yield.
