水平井网在石油和天然气的开发中得到了广泛的应用,作为一种高效的开发方式其效率远远超过了常规井网,大幅增加了油气采收率,得到了较好的经济效益和社会效益。本文主要讨论井网密度的影响主要是有水驱控制程度、原油采收率、油井产量、采油速度以及经济效益等五个方面,分析了不同井网类型对开采程度和累计产油量的影响。 Horizontal well network has been widely used in the development of oil and natural gas. As an efficient way of development, its efficiency is far more than that of conventional well pattern, greatly increasing the recovery rate of oil and gas, obtaining better economic benefits and social benefit. This paper mainly discusses the influence of well pattern density mainly on the degree of waterflood control, oil recovery rate, oil well production rate, oil recovery rate and economic benefits, and analyzes the effect of different well pattern types on the degree of recovery and cumulative oil production .
