摘要
海拉尔盆地潜山裂缝性油藏具有断裂带发育、小断层破碎、储层变化大等特点,采用单一的直井开发方式,对断块附近断失层位较多和垂直裂缝发育的储层存在很多不适应性,开发效果较差.针对潜山裂缝性油藏特殊的地质特点,在精细油藏描述的基础上,研究了储层裂缝发育特征和油藏类型,提出了采用直井、定向井和水平井多井型综合开发潜山裂缝性油藏,可有效开发油田,增加储量动用程度,提高采收率.
In Hailaer Basin,fractured reservoirs in buried hills are characterized by fracture zone development,small fault breaking up and big difference between reservoirs..If adopting development mode of straight wells,there will be much inadaptability and poor development response for reservoirs of faulted horizon being more near faulted block or vertical fracture development.Based on fine reservoir description,this paper deals with the characteristics of the fractures in reservoir and reservoir type,and provides a method of comprehensive development of fractured reservoirs in buried hills with multiple well types to bring about the desired result of effectively developing oil fields,increasing reserve tapping efficiency and enhancing oil recovery.
