CCUS-EOR scheme design and parameters optimization for Gulong shale oil
摘要
Abstract
In"dual carbon"context,Carbon Capture,Utilization and Storage-Enhanced Oil Recovery(CCUS-EOR)is a major technology for carbon emission reduction of petroleum enterprises.Rich resources of Gulong shale oil pro-vides a huge space for CO2-EOR and CO2 storage.Faced by challenge of low primary recovery of OOIP of shale oil,limited producing range of CO2 huff and puff and liable to inter-horizontal wells gas channeling with CO2 injection displacement,geological characteristics,fracturing stimulation and economic cost are analyzed combining with characteristics of Gulong shale reservoirs,and scheme design is determined with idea of vertical wells initiating plane fractures and interwells linear CO2 injection displacement.In order to verify the feasibility of the scheme,nu-merical simulation model of 1 injector and 2 producers is established combining with laboratory experiment results of CO2 injection displacement for Gulong shale oil.Parameters of CO2 injection displacement in vertical wells for Gu-long shale oil is designed and optimized by numerical simulation method.The results show optimal injector-produc-er spacing of 80,120 m and optimal injection rate of 90 t/d for CO2 injection displacement in vertical wells.This scheme can realize effective producing of matrix oil of Gulong shale.The research provides reference basis for CO2 injection development of Gulong shale oil and CO2 storage.关键词
