摘要(Abstract)：

在老区稳产和新区上产难度越来越大的形势下,为有效提高低渗透油藏采收率和储量动用率,吉林油田提出转变开发方式,全面推进气驱开发的发展战略。从油田资源特点出发,对气驱开发的技术需求、可行性和潜力进行分析,对矿场试验和工业化推广作出部署。吉林油田拥有丰富的CO_2资源,可动用储量具备形成年产200×10~4t CO_2的产能规模。适合气驱的油藏储量资源规模较大,混相和近混相驱石油资源占39.9%。气驱开发将以CO_2混相驱技术为引领,逐步拓宽气驱类型。在长岭气田周边优先开展CO_2驱,在距离CO_2气源较远的油田开展空气驱,规划2020年气驱年产油量达到80×10~4t。吉林油田气驱开发具有资源优势和技术基础,潜力很大。
In the situations of the stable production in the mature area and growing difficulty in the production increase in the new area,in order to effectively enhance the oil recovery and reserve produced ratio in Jilin Oilfield,the strategies of changing the development mode and fully carrying out gas flooding development are put forward.From the viewpoint of the reserves characteristics,the following analyses are conducted:the technical requirements and feasibility and the potential of the gas flooding,and moreover the field test and industrial popularization are arranged.There are abundant CO_2 resources in Jilin Oilfield,the movable reserves can reach the productivity scale of2×10~6 t CO_2 per year.And furthermore the reserves in the reservoirs that can be gas flooded are greater,miscible and near-miscible reserves cover 39.9%.The technique of CO_2 miscible flooding takes the lead in the gas flooding development,and then other types of the gas flooding are gradually adopted and expanded.The CO_2 flooding will be first carried out in the area around Changling Gasfield,while the air flooding in those oilfields remote to CO_2sources will be operated.It is planed that the annual production of the gas flooding will reach 80×10~4t in 2020.The gas flooding possesses the dominance of the resources and technical basis,so the potentials are great.
