Problems solved by technology

However, there are generally two problems in the existing filters. One is that when the dirt holding capacity reaches a certain amount, the injection is stopped during cleaning, and the pressure in the well is used for reverse flushing. Because the liquid flow rate on the surface of the filter element is low, the surface of the filter element cannot be thoroughly cleaned. and dirt in the filter
The second is that in order to achieve a higher filtering effect, the specification of the filter element is micron, and mechanical impurities and scale

The lower side of the right end of the water inlet pipe is provided with a sewage outlet connecting pipe, the liquid inlet connecting pipe is arranged on one side of the sewage outlet connecting pipe, and communicated with the sewage outlet connecting pipe; the left end of the shell is welded with a jet, and the copper nozzle is located at The inside of the casing is threadedly connected with the injector. The invention has the advantages of strong self-cleaning ability, safe and convenient operation and high degree of automation.

Description

technical field [0001] The invention relates to a filter device in the reinjection process of oil field sewage, in particular to a high-speed jet self-cleaning filter device. Background technique [0002] For oilfields developed by water flooding, in order to protect the environment and control costs, sewage reinjection after separation of produced fluid has become an important means of oilfield development. In order to ensure the qualified rate of sewage water quality, installing filters on the water injection pipeline is the key to ensuring water quality important method. However, there are generally two problems in the existing filters. One is that when the dirt holding capacity reaches a certain amount, the injection is stopped during cleaning, and the pressure in the well is used for reverse flushing. Because the liquid flow rate on the surface of the filter element is low, the surface of the filter element cannot be thoroughly cleaned. and dirt in the filter. The sec...
