下二门油田剩余油分布状况及控制因素分析

The Status and Dominant Factors of Oil Remained Distribution in XiaErMen Oil Field.

下二门油田是典型的断块油田 ,经过长期高速开发 ,剩余油分布较为复杂。文章概述了下二门油田剩余油总体分布状况和沉积微相与剩余油分布的关系 ,并从沉积模式、地质因素和井网因素三大方面对核三段剩余油形成的控制因素进行了归纳总结 。

XiaErMen oil field is a representative fault oil field. Remained oil distribution is very complex in virtue of long-term quick exploitation. This article not only summarizes the collective character of remained oil distribution and the relation with sediment facies, but also concludes dominant factors that effect remained oil distributing in H3 segment from three aspects: sediment models, geology and wells network,which are applied to deploy and optimize wells network.
