黄沙坨油田为今年来辽河油田在外围滚动开发中取得效果较好的几个区块之一,其内部发育受岩性、构造双重因素控制的边、底水块状裂缝性油藏,开发初期产量较高,但从2004年起,进入到产量递减阶段。本文综合运用油藏地质学、油藏工程学等学科分析了该油田的油藏特征和目前存在的问题,结合国内外同类型油藏的开发实例,认为针对黄沙坨油田的特点,水平井技术能够改善其开发效果,提高采收率。
The Huangsha Tuo Oilfield is one of several blocks that have achieved good results in the rolling development of the Liaohe Oilfield this year. The development of the block-shaped and fractured reservoirs of edge and bottom water under the dual control of lithology and structure has been developed The initial output is high, but from 2004 onwards, it entered the phase of declining production. Based on reservoir geology and reservoir engineering, this paper analyzes the reservoir characteristics and current problems in this field. Combining with the development of similar reservoirs both at home and abroad, it is considered that for the characteristics of Huangsha Tuo Oilfield, horizontal wells Technology can improve its development effectiveness and increase oil recovery.
