摘要(Abstract):

大庆长垣喇、萨、杏油田自2004年开始综合含水率超过了90%,进入到特高含水期开发阶段。这一阶段的油田开发特点、开发规律与中高含水期有着较大的差别。根据大庆长垣油田的开发经验,结合油藏工程方法,对特高含水期的开发规律、开发特点进行了较为详细的阐述,明确了特高含水期的水驱开发效果评价指标,指明了主要开发调整技术措施,为寻求砂岩油田特高含水期控含水、降递减的方法提供了技术支撑。
The comprehensive water cuts of Lasaxing Oilfields in Daqing Placanticline have exceeded 90% since2004,and reached the development stage of the extra-high watercut stage,thus there exist much bigger differences in the development characteristics,development laws comparing with the medium and low watercut stages. According to the development experiences of Daqing Placanticline Oilfields,integrating with the oil reservoir engineering methods,the detail descriptions were conducted for the laws and characteristics stated above at the extra-high watercut stage,thus the evaluating indexes for the waterflooding development effects at this stage were ensured,and moreover the main development adjusting measures were made clear,therefore the technical supports for the water control and decline reduction methods of the sandstone oilfields at the extra-high watercut stage.
