摘要
罗27长4+5油藏裂缝性特低渗油藏于2009年开始规模开发,属于岩性油藏,其油层主要为大规模的湖泊三角洲相沉积。油藏分注区注采关系复杂,精细管理难度大,稳产难度大。该油藏目前已经进入中含水开发阶段,随着注水开发时间的延长和采出程度的增加,主力油层见水,含水上升速度加快,见水井不断增加,剖面和平面矛盾加剧,油田递减加大,稳产形势严峻。
The fractured ultra-low permeability reservoir of Luo 27 Chang 4+5 reservoir began to develop in scale in 2009.It belongs to lithologic reservoirs,and its oil layer is mainly composed of large-scale lake delta facies deposition.The injection-production relationship in the reservoir sub-zone is complicated,the fine management is difficult,and the stable production is difficult.The reservoir has entered the middle water-bearing development stage.With the extension of water injection development time and the increase of production degree,the main oil layer sees water,the water-bearing rising speed is accelerated,see the water well increase,the contradiction between the section and the plane is intensi?ed,and the oil?eld diminishing increases.The stable production situation is grim.
