外围油田井口组合阀的应用及分析

Application and Analysis of the Well Combination Valves of the Peripheral Oilfield

为解决散装式井口工艺复杂、保温性能不好、操作不便的问题,大庆外围油田应用了组装化井口组合阀。该组装化井口组合阀即可满足油田生产需要,又简化了井口工艺,便于操作管理,并且具有防盗及回收套管气的作用。该组合阀在应用过程中根据现场情况不断进行更新改进,目前已拥有适合于单管电加热集油流程和环状掺水集油流程工艺的井口组合阀,并可根据油井计量方式及工艺需要增设计量出口、掺水进口等,使井口组合阀更能发挥其流程简单、易操作、好管理的特性,满足油田生产管理需要。

To solve the problems of complexity process, pool heat preservation and incon-venient operation of bulk wellhead, assembled wellhead combination valves have been ap-plied in peripheral oil field consecutively, which not only fulfills the crude oil production tasks, simplifies the wellhead process, but also prevent oil from being stolen and gather cas-ing pipe gas. The assembled wellhead combination valves have been updated based on the feedback from the oil field. According to the practical need of oil well metering mode and wellhead process, the metering outlet and the watering inlet can be redesigned to meet the characters of simple process and operation.
