摘要
“十一五”期间大庆油田整体上已进入高含水和高采出程度时期开采,目前,70%的可采储量位于高含水层,但主力老油田仍是油田开发的主体;聚合物驱仍是主要的提高采收率技术,但开采对象已由北部的主力油层转向南部的主力油层和北部的二类油层;外围油田也是增加可采储量的主要方向,但90%的储量位于特低丰度、特低渗透及复杂断块油藏。该文深入分析了“十一五”油田开发面临的主要矛盾和问题,研究了油田主要开发调整潜力,提出了油田开发调整的主要技术措施,为油田开发调整及科研攻关指明了方向,为大庆油田“十一五”开发部署提供了重要依据。
Daqing Oilfield has entered the stage of high water cut and high recovery degree during the eleventh five-year plan. At present, 70% recoverable reserves are located in high water cut layers, and the major old oilfields are still dominant for oilfield development. Polymer flooding is still the main EOR technique, but production target has transferred from major reservoirs in the north to major reservoirs in the south and second-class reservoirs in the north. Peripheral oilfields are also the main direction to increase recoverable reserves, but 90% reserves are located in ultra-low abundance, ultra-low permeability and complex fault-block reservoirs. Starting from present development status of Daqing Oilfield, this paper analyzes main contradiction and problems of oilfield development during the eleventh five-year plan, studies main adjustment potential for oilfield development, and proposes major technical strategy for oilfield development adjustment so as to point out direction for oilfield development adjustment and scientific research, and also provides important foundation for development deployment during the eleventh five-year plan.
