本申请是关于一种井丛场污水回收系统,属于石油开采技术领域。所述井丛场污水回收系统包括凹沟、电缆沟、排水沟、污水回收装置、井丛场围栏、热成像摄像头和控制设备,凹沟和电缆沟分别设置在抽油机组的两侧,两条排水沟分别设置在抽油机组和采油树组的两侧,污水回收装置包括含油污水池、排水池、外输管线、排水管线、含油污水管线和连通管线,含油污水收集沟与含油污水池相连通,排水沟均与排水池相连通,第一液位计、第一水泵、第一电磁阀、第二电磁阀、第二液位计、第三电磁阀、第二水泵和热成像摄像头分别与控制设备电性连接。采用本申请,输送到外输管线中的含油污水中的石油含量相对较高,增大了对含油污水进行石油回收处理的效率。
The invention relates to a multiwell cluster field sewage recovery system, and belongs to the technical field of oil exploitation. The system comprises a groove, a cable trench, drainage ditches, a sewage recovery device, a multiwell cluster field fence, a thermal imaging camera and a control device, wherein the groove and the cable trench are arranged on the two sides of an oil pumping unit set respectively, and the two drainage ditches are arranged on the two sides of the oil pumping unit set and the two sides of a Christmas tree set respectively. The sewage recovery device comprises an oily sewage tank, a drainage tank, an output pipeline, a drainage pipeline, an oily sewage pipeline and a communication pipeline, wherein an oily sewage collection ditch is communicated with the oily sewage tank, and the drainage ditches are communicated with the drainage tank. A first liquid level meter, a first water pump, a first electromagnetic valve, a second electromagnetic valve, a second liquid level meter, a third electromagnetic valve, a second water pump and a thermal imaging camera are electrically connected with the control device. By adopting the system, the content of oil in the oily sewage conveyed into the external conveying pipeline is relatively high, and the oil recovery treatment efficiency of the oily sewage is improved.
