发布时间：2019-05-30 08:31
【摘要】：本文针对姬塬油田樊学区域开采现状及存在的问题,对区块的开发方式、开发层系、井网部署、压力系统及技术政策等进行分析、论证,提出适合本区块的注水开发方案。结合静、动态的资料,建立数值概念模型,对裂缝方向与注采井网的适应性及井网部署进行数模计算。分别将裂缝的方向与注采井排的夹角设置为0°、45°、90°进行数值模拟,模拟结果表明,当夹角为0°时的开发效果较好。在井网优选方面,对6种井网类型分别进行了数值模拟计算,结合油藏工程方法与数值模拟的结果,综合表明初期选用菱形反九点法较好。确定井排方向为北东55o,裂缝方向上的注水井距为240m,排距为80m。文中综合多种方法确定单井产能为0.41t/d,并运用经验公式计算单井日注水量为3.1m3/d。
[Abstract]:In view of the present situation and existing problems of Fanxue area in Jiyuan Oilfield, this paper analyzes the development mode, development layer system, well pattern deployment, pressure system and technical policy of the block, demonstrates and puts forward a water injection development scheme suitable for this block. Based on the static and dynamic data, a numerical conceptual model is established to calculate the adaptability of fracture direction and injection-production well pattern and the deployment of well pattern. The angle between fracture direction and injection-production well row is set to 0 掳, 45 掳and 90 掳respectively. The simulation results show that the development effect is better when the angle is 0 掳. In the aspect of well pattern optimization, the numerical simulation calculation of six types of well pattern is carried out respectively. combined with the results of reservoir engineering method and numerical simulation, the comprehensive results show that the rhomboid reverse nine point method is better in the initial stage. The well row direction is determined to be 55o in the northeast, the injection well spacing in the fracture direction is 240m, and the row spacing is 80m. In this paper, the productivity of a single well is determined to be 0.41t / d by using various methods, and the daily water injection volume of a single well is calculated to be 3.1m3 / d by using the empirical formula.
