摘要/Abstract

摘要：

针对长庆油田低渗透储集层岩性致密、注水受效不均衡、单井产量低、平面非均质性强等导致地下水驱不均的问题,依据低渗透油藏水驱理论建立基础模型,并考虑注采井网中生产井的干扰,根据势的叠加原理,引入生产井影响因子系数,建立了井组单元内水驱前缘的简易确定方法。将该方法应用于鄂尔多斯盆地某超低渗透油藏加密调整部署,通过生产实例验证,该方法简便易行,计算结果可靠。

关键词: 低渗透油藏, 生产动态, 水驱前缘, 水驱半径, 注采井网, 势的叠加原理, 加密调整

Abstract:

In view of the problems encountered in the low permeability reservoirs in Changqing oilfield, such as tight lithology, poor water injection efficiency, low single well production and strong plane heterogeneity, which lead to uneven waterflood, the paper established a basic model on the basis of waterflooding theories in low permeability reservoirs, considered the interference of production wells, introduced the factors influencing production according to the potential superposition principle, and established an easy method to determine waterflood front in a well group. This method has been applied in infill drilling adjustment of a low permeability reservoir in Erdos basin and the production cases can prove the feasibility and reliability of the method.

Key words: low permeability reservoir, production performance, waterflood front, waterflood radius, injection-production well pattern, poten- tial superposition principle, infill drilling adjustment
