××开发区于80年投入开发,基础井网采用450米井距的反九点法面积注水井网,井网密度3.2口/平方公里,一套层系开采葡I组油层;1994年进行一次加密调整,注采井距缩短为225米,采用斜反九点法面积注水井网,井网密度为5.7口/平方公里;2002年由于内部补充的需要,进行注水井钻关,通过对××开发区钻关过程中油水井的动态变化特征进行分析,找出产量变化规律,对影响产液量下降幅度的主要因素进行分析,根据油井动态变化规律来确定钻关恢复注水原则,从而得出对钻关的认识,为以后钻关提供一些经验。
× × Development Zone was put into development in 1980. The foundation well network adopted the anti-nine-point area injection well pattern with a well spacing of 450 meters. The well density was 3.2 ports per square kilometer. Encryption adjustment, shortening injection and production well spacing of 225 meters, the use of oblique nine point area of injection well pattern, well pattern density of 5.7 mouth / square kilometers; in 2002 due to the need for internal replenishment, drilling wells, through the × × dynamic change characteristics of oil and water wells in the process of drilling and boring in the development zone to find out the law of the variation of output and analyze the main factors that affect the rate of liquid production decline and determine the principle of recovery and waterflooding according to the dynamic variation of oil well Knowledge of the drill, to provide some experience for future drilling.
