摘　　要：为实现油田集输站场工艺简化优化、密闭橇装化,停用部分老旧高耗能设备,最大程度实现站场简化降级、无人或少人值守,因此开展多相流密闭混输技术研究与应用。该技术利用离心式双腔混输装置将油、气、水混合介质同时增压输送,实现多相流密闭混输,同时集成集油、计量、增压及自动化控制等功能,形成橇装化装置,实现“一橇代站”密闭集输,有效解决了传统油气混输泵效率低、易损坏、含气率限制等技术难题。在两座转油站试验应用多相流密闭混输技术后,停用了原计量阀组、储油罐、输油泵等工艺设备,采取无人值守方式,成功实现了密闭混输、自动计量与控制。结果表明在转油站应用该技术可实现气液密闭混输、工艺简化优化、降低油气损耗,达到站场降级、减员增效的目的,其经济效益和社会效益可观。In order to realize the process simplification and optimization,airtight and skid-mounted of oilfield gathering and transportation station,stop using some old and high energy consumption equipment,and realize the simplification and degradation of the station to the maximum extent with no or few people on duty,research and application of multiphase flow airtight mixed transportation technology are carried out.The technology pressurizes and transports the oil,gas,and water mixed media at the same time by using the centrifugal double-chamber mixed transportation device.It realizes the airtight mixed transportation of multiphase flow,and integrates the functions of oil gathering,metering,pressurizing,and automatic control at the same time,forms a skid-mounted device,and realizes the use of“skid instead of station”for airtight gathering and transportation.The technical problems such as low efficiency,easy damage,and limited gas content of traditional oil-gas mixed transportation pump are effectively solved.After the trial application of multiphase flow airtight mixed transportation technology in two oil transfer stations,the original metering valve group,oil storage tank,oil pump,and other process equipment are stopped,and the unattended mode is adopted,airtight mixed transportation,automatic metering and control are successfully realized.The results show that the application of this technology in oil transfer stations can realize airtight gas-liquid mixed transportation,process simplification and optimization,and reduce the oil and gas loss,achieve the purpose of station degradation,reducing staff and increasing efficiency,which has considerable economic and social benefits.
