Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] figure 1 The structure of a treatment device for oil and gas field produced water (hereinafter referred to as "treatment device") 100 according to the present invention is schematically shown.

[0024] The processing device 100 includes an evaporation chamber 1 and a liquid supply channel 2 extending into the evaporation chamber 1 . The liquid supply passage is configured so that a liquid can pass therethrough and feed the liquid into the evaporation chamber 1 . The water contained in the liquid will evaporate from the liquid in the evaporation chamber 1, whereby the amount of liquid can be reduced.

[0025] It should be understood that, in the case of using the treatment device 100 to treat the oil and gas field produced water, the oil and gas field produced water can be directly supplied to the evaporation chamber 1 through the liquid supply channel 2, or the oil...

Abstract

The invention relates to a treatment device for oil and gas field produced water, which comprises: an evaporation chamber, and a liquid supply channel extending into the evaporation chamber, and the liquid supply channel is configured to supply liquid to the evaporation chamber. The use of this treatment device for oil and gas field produced water can reduce the amount of saline sewage produced by oil and gas field produced water.

Description

technical field [0001] The invention relates to the treatment of produced water in oil and gas fields, in particular to a treatment device for produced water in oil and gas fields. Background technique [0002] Produced water in oil and gas fields is mainly water in the formation structure, which is brought to the surface along with crude oil and natural gas during the process of oil and gas production. The water quality of produced water in oil and gas fields is very complex, mainly including water, oil, suspended solids, calcium and magnesium in the produced water in the form of ions and other scaling components, bacteria, and various chemicals added during oil production (such as foaming agents) , a large amount of chloride ions, etc. [0003] In the prior art, membrane filtration technology is usually used to treat oil and gas field produced water. However, it is difficult to separate the salt ions dissolved in water by this treatment method, and the cost of this treat...
