摘　　要：随着油田开发进入高含水后期,低沉没度、供液不足的低产油井逐年增多。对这类油井采取低液面间抽生产是一种有效节能办法。在葡萄花油田,年度采取低液面间抽生产井达到2500井次,占全部开井数的22.6%,为实现降本增效和节约能耗,在保持日产油量稳定情况下,采取液面恢复和下降公式制定低液面间抽制度,结合"峰谷平"电价收费方式,制定适合葡萄花油田的低液面间抽制度。通过对比间抽前后的生产情况,在保障日产油量稳定前提下,单井日节电32.63 k Wh,取得了良好的节电效果。As the oilfield has entered into the later stage of high- water- cut period, stripper wells with low submergence and inadequate fluid increase year by year. And for this kind of oil wells,low-liquid-level interval pumping is an effective production method. In Grape Flower Oilfield, the annual amount of wells that using low-liquid-level interval pumping reaches 2 500, accounting for 22.6% of the total number of wells. For lowering cost, improving efficiency and saving energy consumption and on the premise of stable daily oil production, liquid level recovery and falling formula for low-liquid-level Interval pumping system is taken. Combined with the electric charge calculation method of 'peak, valley, plain', the low- liquid- level interval pumping system that suitable for Grape Flower Oilfield is developed. Through comparing the production status before and after interval pumping, single well can save electricity 32.63 kWh/d on the premise of stable daily oil production, which achieves good economic and social benefits.
