摘要: 新场蓬莱镇组气藏为中国石化西南油气分公司开发最早、采收率最高的低渗致密砂岩气藏。目前气藏已进入开发后期,地层压力及剩余储量丰度低,进一步提高采收率并获得经济效益难度大。为保证气藏持续效益开发,需定量评价气藏效益开发潜力。为此,以建模数模一体化为手段,以经济技术一体化评价为核心,开展气藏采收率多因素敏感性分析,研究不同气价、不同内部收益率及不同地层压力条件下的不同井型效益开发储量丰度下限,建立气藏效益开发潜力评价动态模型,评价不同开发阶段及不同经济政策下气藏开发潜力。经实际开发井验证,效益开发潜力评价模型准确度高,与实际部署井经济效益符合率达到88%,净利润1 087万元。

Abstract: Xinchang Penglaizhen Formation gas reservoir is a typical low permeability tight sandstone gas reservoir with the earliest development and highest recovery in Southwest Petroleum Branch, SINOPEC. The gas reservoir has entered the later stage of development, it is difficult to enhance gas recovery and economic benefits, because it has low formation pressure and low abundance of remaining reserves. In order to ensure the sustainable development of gas reservoirs, it is necessary to evaluate the potential of gas reservoir development quantitatively. By means of analog integrated modeling and with the economic and technological evaluation at the core, We carried out the multi-factor sensitivity analysis of gas reservoir recovery, and studied the lowest reserve abundance for different well types under different gas prices, different internal rates of return and different formation pressures. The evaluation model of benefit development potential of Xinchang JP gas reservoir was established to evaluate gas reservoir potential at any development stage and under different economic policies. The efficiency development potential evaluation model has high accuracy, and the coincidence rate with the actual deployment well economic benefit is 88%, and the net profit is 10.87 million yuan.

Key words: low permeability tight sandstone gas reservoir, economic and technological integration, internal rate of return, formation pressure, evaluating potential
