火烧油层技术在胜利油田的应用

针对胜利油田稠油油藏类型复杂、油层性质差异大、多数区块已进入多轮次蒸汽吞吐后期、开采难度增大的特点,开展了火烧油层技术试验,详细介绍了该技术在J10-13-5井和CN95-2井的试验情况,并对试验效果作了分析.现场试验表明,火烧油层技术在低渗透稠油井和蒸汽吞吐过的稠油井上应用效果较好.胜利油田火烧油层技术在点火工艺、室内物理模拟、动态监测、注气工艺等方面取得了突破,为该技术的进一步推广应用奠定了基础.

Applications of Combustion Drive in Shengli Oilfield

Aiming at complex kinds of heavy oil reservoirs, big differences among layers and the facts that most blocks are in later period of s team huff and puff processes, and difficult to be produced, we carried out exper iments of in-situ combustion. This technology is more adaptable than steam inje c tion. We finished in-situ combustion experiments in three kinds of wells: in al l of high permeability heavy oil wells, low permeability heavy oil wells and heav y oil wells, all of which were treated with steam injection before. The field ex periments show that in-situ combustion technology has achieved breakthrough in i gnition process, laboratory physical simulation, dynamic monitoring and air inje ction process. It will guarantee the successful exploitation of hard-to-produc e heavy oil reserves with in-situ combustion process.
