孤岛稠油高效开发的主要做法

Main Practice for High Efficient Development of Heavy Oil in Gudao Oilfield

孤岛稠油油藏条件复杂,开发难度大,近年来,通过攻关技术、优化转周、推广汽驱,使低品位稠油储量得到高效动用,老井高轮次吞吐后综合递减率得到控制,蒸汽驱规模和效果不断扩大,实现了孤岛稠油高效开发,为采油厂产量稳定运行发挥了重要作用。

In Gudao Oilfield,conditions of heavy oil reservoir were complex and it was difficult for development.In recent years,through the technologic research and development,the interval of steam huff and puff was optimized,steam flooding area was expanded,thus low-grade heavy oil reserves were effectively produced,the composite declining rate of high speed steam huff and puff was controlled,the scale and effect of the steam flooding were expanded,the high efficient development of the heavy oil was realized in Gudao Oilfield.It plays an important role for stable production operation in oil production plant.
