海上油田低产低效井筛选标准研究

Research on the Rules about Low Production and Deficient well of the Offshore Oilfield

目前国内海上油田没有统一的界定低产低效井的标准,常常以经验判断为主。本文运用经济评价方法,计算单井的经济效益大小,建立新井和老井两种情况下的低效井经济界限模型。该方法在渤海A油田得到了实际应用,筛选出低效井,并开展了油井的综合治理,取得了不错的效果,为油田的管理工作指明方向。研究认识对海上其它油田的低产低效井筛选治理工作开展提供了可靠的经验。

The unified rules about the low production and deficient well of the offshore oilfield are not established , the selected wells are always according to the experience. Base on the economic evaluation , the value of every well is evaluated ,the economic model about the new well and the old well are built up. This method used in the A oilfield of Bohai bay , the low production and deficient wells are selected and the treatment put into operation, the effect are very good. It is good example for other offshore oiIficld to select the low production ,deficient well.
