摘要
按照油层有效厚度和渗透率的大小 ,并考虑原油的生产能力 ,以姚 1 1 3、南 71、姚 1 1 0和姚 63井开发数据为代表 ,将川口油田分为 4类地质模型。运用 VIP三维三相黑油模型软件 ,模拟预测该区 4类模型 1 5 0 m注水式开采 ,1 5 0 ,2 0 0 m枯竭式开采 ,以及 类模型 1 5 0 ,2 0 0 ,2 5 0 m等井网井距条件下注水式开采的平均单井产气量。结果显示 ,投产后 8～ 1 2年内 ,注水式开采可得 2 0～ 1 0 0m3 /d的稳定气流 ,枯竭式开采可得 2 0～ 60 m3 /d的稳定气流 ,全区产量不低于 2× 1 0 7m3 /a。在此基础上 ,从能量、环境、经济的角度论证 。
According to the effective pay thickness, the permeability of the reservoir layer and the productive ability of crude oil in Chuankou Oil Company, a synthetical study was made on the basic geological data and the 4 typical wells exploitative data of Yao 113, Nan 71, Yao 110 and Yao 63, then the tract of Chuankou Oilfield into was divided into 4 types. By using VIP(Vector concealed programme) Black Oil software, modeling 150m water flooding exploitations, 150 m and 200 m dry up exploitations as well as the 150 m, 200 m and 250 m water flooding exploitation of typical modelⅠ. the results indicate that after 8～12 years of production, 20～100 m 3/d of gas outputs per well can be got by water flooding exploitations and 20～60 m 3/d by dry up exploitations. The total output is at least 2×10 7 m 3/a. From the point of energy, environment and economy, the urban natural gases′ delivery and distribution plan is the best.
