摘要/Abstract

摘要： 针对胜利油区目前高含水和特高含水的现状,从经济效益的角度出发,根据胜利油田的实际生产资料,建立了采收率与井网密度的定量关系,考虑井的基本建设投资和投资回收期内生产经营费用,利用盈亏平衡原理,解出合理井网密度的表达式,并对胜利油田分高渗透和低渗透两类共50个单元的合理经济极限井网密度进行了测算验证,为油田开发决策和生产运行提供可靠的科学依据。

关键词: 高含水期, 经济效益, 井网密度, 采收率, 可采储量

Abstract: In view of Shengli oilfield's current situation of high or extra-high water cut, and economic efficiency based on oilfield's actual data, this paper established the quantitative relationship between oil recovery and well spacing density. It takes into consideration the investment on infrastructure and the operating and management spending during investment pay out period etc, using the principle of loss-and-gain balance, this paper formulated the expression of rea- sonable well spacing density. This formula has been applied and verified in Shengli oilfield, on to high and low permeabilty reservoir of fifty units altogether which have been classified into two categories: high-permeable and low permeable. It prov ide reliable scientific basis for oilfield development decision making and production operation.

Key words: high water-cut stage, economic benefit, well spacing density, recovery factor
