摘要
大庆油田目前已进入特高含水期的开发阶段,但检查井及动态监测等资料结果表明三类油层还有相当一部分储量动用差或不动用.由于这部分剩余油在空间上分布比较复杂,且目前薄差层的水淹层解释精度远远不够,使三类油层三次加密选井选层难度加大,加密井初期含水高,经济效益不理想,因此提出三类油层开发不能单纯靠水驱加密调整,有必要采取加密与三次采油技术相结合的开发方式,高效开发三类油层.同时针对目前复杂的层系井网现状,确定该方式下三类油层层系组合、井距和井网部署方式.
The Daqing oilfield has already entered super-high water-cut stage,but data of inspection well and monitoring import that tertiary-main layers still have a very large quantity remained.Because this part of surplus oil distributes on spaces more complicated,and the accuracy to explain waterflooding of the thin bad layer is far from enough,this makes it difficult to choose wells and layers in the third infilling adjustment of tertiary-main layers.And infilling well in the early stage has a high content of water and the economic profit is very low,so development of tertiary-main layers can＇t merely depend on third infilling adjustment.It is necessary to combine infilling together with tertiary recovery so as to develop tertiary-main layers efficiently.And in this way,certain layers combination,well spacing and well pattern arrangement were determined.
