单家寺单56块超稠油油藏在2001年投入开发,随着开发时间的延长,逐步进入高轮次吞吐阶段,最高吞吐周期达到12个,暴露出油井含水升高、井距偏大、停产井增多、井网不完善等问题,开发效果逐渐变差。为进一步提高蒸汽吞吐采收率,经过实施,改善了单56块开发效果,进一步提高了超稠油油藏采收率,为同类型稠油油藏提供了借鉴经验。 Single monastery single 56 super heavy oil reservoir was put into development in 2001, with the extension of development time, and gradually into the high rounds of throughput phase, the maximum throughput cycle reached 12, exposing the well water content increases, the well is too large , Stop production wells increased, well network imperfections and other issues, the development effect gradually worsened. In order to further enhance the recovery rate of steam huff and puff, the implementation of this project has improved the development effect of single 56 units and further enhanced the recovery rate of ultra-heavy oil reservoirs, thus providing reference for the same type of heavy oil reservoirs.
