文留西部极复杂断块分层系精细评价研究

Separate layer fine evaluation of ultra-complex fault block in the west zone of Wenliu

文留西部是东濮凹陷油气富集区带之一,受文西断裂及其补偿断层的控制,断层切割关系复杂,属典型的极复杂断块油气藏。近年开展以"精细"为主导思想的滚动勘探及油藏评价研究工作,通过分层系、分砂组整体精细评价、及相控储层预测等技术的应用,不断取得新认识,实现了老区扩边,落实了一批新的优质可动用石油储量。

The west zone of Wenliu,an oil and gas accumulation zone in Dongpu sag,is controlled by Wenxi fault system and compensation faults with complex crosscutting relationship.It has typical ultra-complex fault block oil and gas reservoir.Guided by fine study,rolling exploration and oil reservoir evaluation studies have been carried out in recent years.Based on fine evaluation for separate layers and sand groups and technology application(facies-controlled reservoir prediction,etc.),new understandings have been obtained with realization of extension in development zones and good produced OOIP.
