油井综合利用率变动情况分析研究

PROBE ON DYNAMIC SITUATION ANALYSIS OF COMPREHENSIVE USE OF OIL WELLS

油井利用情况对原油生产量影响很大。在地质条件和油井数量不变的情况下 ,加强油井管理 ,减少关井 ,增加采油时间 ,改善油井的利用情况 ,就可以达到生产更多的原油。油井利用情况 ,包括两个方面因素 :一是改善油井的利用 ,使本期应采油的油井尽可能投入开采 ;二是投入开采的油井在日历时间内尽可能充分利用。文章通过对油井的时间利用指标的计算和分析 ,运用指数分析的原理 ,从计划开井口数、油井利用率和采油时率的变化 ,分别对影响油井时间利用和油井综合利用率进行了分析 ,找到影响油井时间利用和油井综合利用的主要因素 。

The use of oil wells has a critical influence on productivity, which includes two factors: to improve the use of the wells, so as to produce the wells as many as possible; on the other hand, to make full use of the producing wells in the life time. By calculation and analysis of time-use index of oil wells, and the principle of index analysis, the factors of impacting time-use and comprehensive use of oil wells is analyzed respectively based upon planed number of penetrating wells, use rate of oil wells and recovery rate, the main factors influencing time-use and comprehensive use of oil wells are determined, and the time-use of oil wells is promoted.
