摘要: 冀中坳陷主力潜山油藏已进入"双高"开发阶段,剩余地质储量近4×108t,潜力巨大。储-盖条件优越、含油幅度大,区域位置毗邻京、津、雄和陕京二、三线,具备注气重力驱、改建储气库的有利条件。另外,油藏普遍具有一定的边底水能量,地层温度为70~140℃,伴生丰富的地热资源。实施潜山油藏效益开发与提高采收率重大战略工程,对于盘活冀中地区潜山热储资源具有重大意义。对冀中坳陷潜山油藏开发与综合利用技术现状进行了梳理,包括控制强度采油、降压开采、调剖堵水、风化壳及低渗带挖潜、地热利用、注气驱油、改建储气库7个方面。结合当前能源形势、技术风险与效益分析认为,碳驱油碳埋存(CCUS-EOR)、天然气驱协同储气库、氮气重力驱、降压开采协同地热利用将是潜山油藏未来最具发展潜力的综合利用技术,但也面临着老井井况差、混相重力驱机理不明确、碳源供应短缺、油田开发与地热利用各自为政、配套工艺不完善、投资规模大等挑战,研究成果以期为潜山油藏的开发调整提供参考借鉴。

Abstract: The main buried-hill reservoirs in Jizhong depression have entered in the stage of high water-cut and high-recovery development, where the remaining geological reserves are approximately 400 million tons, demonstrating significant prospecting potential. These reservoirs exhibit superior reservoir-cap conditions, large oil-bearing area, and strategic proximity to Beijing, Tianjin, Xiong'an, and Shanxi-Beijing Ⅱ/Ⅲ pipelines, providing favorable conditions for gas-assisted gravity drainage, and reconstruction of underground gas storage. In addition, the reservoirs generally possess certain edge and bottom water energy, associated with abundant geothermal resources; the formation temperature is as high as 70-140℃. To implement major strategic projects for efficient hydrocarbon development and enhanced oil recovery (EOR)in buried-hill reservoirs is of great significance for revitalizing the buried-hill geothermal and petroleum resources in the central Hebei area. This paper summarizes the status of development and integrated utilization technology for buried hill reservoirs in Jizhong depression, involving intensity-controlled oil production, depressurizing production, profile control and water plugging, potential exploration of weathering crust and low permeability zones, geothermal utilization, gas injection for oil displacement, and gas storage reconstruction. Based on the current energy situation, technical risks, and economic evaluations, it is considered that CCUS-EOR (carbon capture, utilization and storage-enhanced oil recovery), synergy between natural gas flooding and gas storage, nitrogen assisted gravity drainage, and depressurizing production coupled with geothermal utilization will be the most promising comprehensive utilization technologies in the future. However, ongoing challenges include poor conditions of old wells, unclear mechanism of miscible gravity drainage, shortage of carbon sources, separate management of oilfield development and geothermal utilization, incomplete supporting technologies, and large-scale investment.
