【摘要】：針對(duì)CO_2驅(qū)油及封存過(guò)程中的地質(zhì)安全問(wèn)題,利用油氣封蓋理論和油藏工程理論,研究了油藏條件下CO_2驅(qū)油及封存的定量地質(zhì)安全界限體系。研究結(jié)果表明:CO_2驅(qū)油及封存過(guò)程可劃分為CO_2注入驅(qū)油階段、CO_2注入封存階段和CO_2靜態(tài)封存階段;CO_2在油藏條件下存在擴(kuò)散泄漏、低速滲流泄漏和高速滲流泄漏3種泄漏機(jī)理;CO_2的地質(zhì)安全性主要受蓋層巖封堵壓力、斷層巖封堵壓力、斷層重開(kāi)啟壓力、斷層巖破裂壓力及蓋層破裂壓力等的控制。研究成果對(duì)CO_2驅(qū)油及封存項(xiàng)目的選址及風(fēng)險(xiǎn)分析有重要意義。
[Abstract]:Aiming at the geological safety problems in the process of oil displacement and storage of CO-2, the quantitative geological safety limit system of CO-2 flooding and sealing under reservoir conditions is studied by using the theory of oil and gas sealing and reservoir engineering. The results show that the process of oil displacement and storage can be divided into two stages: CO-2 injection and oil displacement stage, COSP _ 2 injection and storage stage and CO-2 static storage stage, and the diffusion leakage exists in the reservoir conditions. The geological safety of CO _ 2 is mainly controlled by the sealing pressure of caprock, the re-opening pressure of fault, the fracture pressure of fault rock and the fracture pressure of caprock. The research results are of great significance to the location and risk analysis of CO2 oil displacement and storage projects.
