静安堡油田沈84 块是一个由多断块组成的被断层复杂化的构造油藏,投产以来暴露出层间干扰严重,水驱程度低的矛盾。通过对沈84 块进行精细模拟,不仅对该块剩余油分布进行了定量研究,为下步方案实施提供了依据,而且对复杂断块油藏的模拟方法进行了有益探索,开展了多断块油藏一体化模拟研究。文中提出的断层密封性判识方法、小层宏观定量分析新概念及剩余储量的定量分析方法对复杂断块油藏研究具有重要价值。

Shen 84 block in Jinganbu Oilfield is a complex structural reservoir by faults composed of multifault blocks. Since the block was put into production , the contradictions , strictly interference and low degree of water drive , were exposed in the block. Through fine simulation to the block , the residual oil distribution was studied quantitatively , providing the guide to the next proect implementation , the simulation method of complex fault-block reservoir was also researched , and wholly reservoir simulation of multi-fault blocks was studied. The distinguishing method of fault sealing property , new concept and method of layers rational analysis were provided in this paper.
