Abstract

The invention relates to an on-line detection device for the oil content of oilfield reinjection water and belongs to the technical field of detection equipment. The device comprises a detection pipeline, a pressure reducing valve, an internal thread lifting check valve, a flange ball valve and a detection part; one end of the detection pipeline is connected out from an opening in the pipe wall of a reinjection water pipeline, and the other end of the detection pipeline returns to the reinjection water pipeline at a certain downstream position in the reinjection water direction; the detection pipeline is inverted-U-shaped; the pressure reducing valve and the flange ball valve are sequentially arranged on one side pipe of the detection pipeline from top to bottom; the internal thread lifting type check valve and the flange ball valve are sequentially arranged on the other side pipe of the detection pipeline from top to bottom; and the detection part is arranged in the middle of the detection pipeline. With the on-line detection device for the oil content of the oilfield reinjection water of the invention adopted, the problems that an existing reinjection water oil content detection method is complex in operation, low in detection efficiency, incapable of displaying oil content changes in time, large in labor intensity, difficult to achieve automatic management of a sewage treatment station and the like can be solved.

Description

Technical field: [0001] The invention relates to the technical field of detection equipment, in particular to an on-line detection device for the oil content of reinjected water in an oil field. Background technique: [0002] my country's oilfield exploitation has basically entered the stage of high water content, and a large amount of oilfield sewage is produced during the exploitation of high water content oilfields. The oilfield sewage is reinjected after being treated up to the standard, and the oilfield water injection is to maintain the formation pressure, improve the recovery rate of the oil reservoir, and ensure the efficient development of the oil reservoir. Oil content is one of the important indicators of reinjection water. High oil content in reinjection water will cause pollution of water injection formations. On the other hand, it will increase the possibility of corrosion of equipment and facilities, which will eventually affect the efficient production of oil...
