鄯善油田中含水期开发技术政策界限研究

THE DISCUSSION OF DEVELOPING TECHNICAL POLICY LIMIT IN MEDIUM WATER-Bearing PERIOD IN SHANSHAN OIL FIELD

鄯善油田已进入中含水期开发阶段,低含水期的技术政策界限已不适应油田目前开发形势。本文运用采油工艺原理、矿场统计法对油田主力区块的注采压力系统进行了研究和评价,并结合油田开发现状,对油田产量递减及含水上升控制界限进行了研究,为鄯善油田今后的开发调整提供了决策依据。

In accordance with the developing situafion of medium water-bearing period in Shanshan Oil Field, the technical policy limit of low water-beaing period has not been meet the oilfield developing situation. The paper gave the discussion and evaluation to injection-production pressure system of main tract, the production deline and limit of water cut control by using oil production technological principle, lease statistics and combining oilfield developing situation. It also provided the decision basis for the next adjusting development in Shanshan Oil Field.
