针对Z43断块普通稠油强边水油藏目前开发中存在的问题，开展了剩余油挖潜技术研究。在控油断层、微构造、隔夹层等地质精细研究的基础上，建立了三维地质模型。开展普通稠油油藏高含水期剩余油分布研究，制定了挖潜方案，提出了常规井、侧钻井继续落实控油断层，短井段水平井挖潜剩余油的思路，现场实施取得了较好的效果。该断块类型油藏的成功挖潜对类似油藏后期开发具有一定的指导意义。
針對Z43斷塊普通稠油彊邊水油藏目前開髮中存在的問題，開展瞭剩餘油挖潛技術研究。在控油斷層、微構造、隔夾層等地質精細研究的基礎上，建立瞭三維地質模型。開展普通稠油油藏高含水期剩餘油分佈研究，製定瞭挖潛方案，提齣瞭常規井、側鑽井繼續落實控油斷層，短井段水平井挖潛剩餘油的思路，現場實施取得瞭較好的效果。該斷塊類型油藏的成功挖潛對類似油藏後期開髮具有一定的指導意義。

Aiming at the existing problems in developing normal heavy reservoirs in fault Z43, remaining oil potential tapping tech-nique of fault block Z43 was researched. On the basis of detailed study of oil-controlling fault, micro structure, interlayer and so on, 3D geological model was built to study the remaining oil distribution during high water cut stage of normal heavy reservoir, make plans of potential tapping and put forward the ideas of continue to implement the oil tomography of regular wells and side-tracking wells and potential tapping of horizontal wells with short section. Site implementation obtained great result. The success of potential tapping of this reservoir block type has significance for the later development of similar reservoirs.
