摘　　要：砾岩油藏的非均质特征决定了砾岩总体开发效果差,尤其在油藏开发进入含水较高的中后期往往出现:油水流动关系复杂,水驱控制程度低,以及井网井距的不适应性导致储量动用程度低,同时地层和油水井井况的问题给油藏的后期挖潜带来困难。针对以上问题利用动态和静态相结合的办法搞清油藏剩余油分布,通过调整注采结构、平剖面压力场、井网井距以及油水井综合措施等方法来提高油藏的采收率。DengShaoqiang, HuangQuanhua , （Southwest Petroleum Institute）, Xiaoli （Exploratory and Development academy of Dagang oil field）, Jinping （Xinjiang Oil field Company）The heterogeneity characteristic of conglomerate reservoir decide it＇s exploitation effectiveness is not well . Especially in the later exploitation ,the conglomerate will facing the follow problems：complex relationship of water and oil ,the water control degree is low,the unadapted pattern well spcing lead to a lower reserves employ degree ,and the bad condition of strata ,oil well and injection well bring much dif（icuhies to the later dug potentiality of conglomerate. Using dynamic and static way to confirm the distribution of remaining oil . According to adjust pour and pluck structure and pattern well spacing, and the comprehensive measures to improve ihe recovery factor of conglomeratc.
