SAGD采油站至联合站间输油一般均采用泵输工艺,存在能耗高、损耗大、安全隐患多等问题。当SAGD开发进入汽腔拓展阶段后,伴生气量大且能保持稳定,为开展自压输油提供了可能。为此,开展了SAGD采油站自压输油技术研究。利用SAGD采油站缓冲罐气顶压力高且较为稳定这一优势,优化原有的集输流程,成功实现无外输动力条件下的自压输油。该技术具有成本低、收益高、减员增效等经济效益和社会效益。该技术在SAGD开发的汽腔拓展、稳定泄油及汽腔下降初期3个阶段均能实现平稳运行,可为SAGD开发技术的推广应用提供技术支持。
Generally the oil between SAGD oil production station and the joint station is transmitted by pumping, with high energy consumption, significant loss and safety hazards. At the stage of steam chamber expansion in SAGD development, there is a great amount of associated gas stably generated, which make it possible to realize self-pressurized oil transmission. Therefore, a study was conducted on the self-pressurized oil transmission technology for SAGD production station. The original gathering and transmission technology was optimized on the basis of high and stable gas cap pressure of the buffer tank in SAGD production station, and self-pressurized oil transmission was enabled without any external force. The technology can bring about such economic and social benefits as low cost, high profit, staff reduction and improved efficiency. This technology has been stably applied in three stages of SAGD development: steam chamber expansion, stable oil drainage and initial steam chamber decline, providing technical support for the promotion and application of SAGD development technology.
