Abstract

A method of enhanced recovery efficiency by CO2 huff and puff was proposed in response to the low recovery efficiency in natural depletion of shale gas reservoirs in Jimsar and the difficulty of traditional recovery enhancement measures to effectively increase the production. A numerical simulation model of reservoir in the work area was established by the numerical simulation method. Test wells suitable for CO2 huff and puff were selected according to the horizontal interval length and reservoir thickness. The decisive role of matrix energy enhancement in CO2 huff and puff was clarified, and the working system of CO2 huff and puff was optimized. Finally, the optimized scheme was applied to the field test. The results showed that, there was fracture channeling between the test wells, resulting in serious gas channeling in the injection stage of CO2 huff and puff, and CO2 did not enter the matrix sufficiently to replace the crude oil, resulting in poor overall development efficiency. The study provides a reference for enhancing oil recovery by CO2 huff and puff in shale reservoir and for adjusting the scheme of development by CO2 huff and puff.

Key words： shale oil; CO2 huff and puff; enhanced oil recovery; reservoir numerical modeling; CO2 storage; Xinjiang Oilfield
