Problems solved by technology
[0002] With the increasing water content in oil well production fluid, the output of production sewage is also increasing, which in turn brings greater pressure on the export system, and also increases the treatment cost of production sewage. At the same time, the long-term Heavy load operation also brings great pressure to operation and safety production

The invention aims to provide an on-site water separation treatment method applied to an oil extraction well of an oil and gas field; a produced oil-water mixture can be quickly and efficiently separated on site, sewage is directly reinjected after being treated to reach the standard, the treatment cost of the production sewage is reduced, and the pressure of an output system and a united station is reduced. The method comprises the steps: step 1, hoisting a dosing device, an on-site water separation device, an oily water buffer tank and an output booster pump beside the oil well through skid blocks, adding a special treatment agent through the dosing device, and then mixing material liquid produced by the oil well and the special treatment agent in a pipeline mixer at the front end of the on-site water separation device; step 2, inputting the mixed material liquid into the on-site water separation device, and carrying out oil-water separation on the mixed material liquid by the on-site water separation device; and step 3, inputting the separated gas phase and oil phase into a ground pipe network of the output system by the on-site water separation device, and inputting the separated water phase into the in-situ water injection buffer tank.
Description
technical field [0001] The invention belongs to the technical field related to oil field exploitation, and in particular relates to an in-situ water separation treatment method applied to oil production wells in oil and gas fields. Background technique [0002] With the increasing water content in oil well production fluid, the output of production sewage is also increasing, which in turn brings greater pressure on the export system, and also increases the treatment cost of production sewage. At the same time, the long-term Heavy load operation also brings great pressure to operation and safe production. Contents of the invention [0003] The purpose of the present invention is to provide an in-situ water separation treatment method applied to oil production wells in oil and gas fields to solve the problems raised in the above-mentioned background technology. It can directly re-inject the sewage treatment on the spot after reaching the standard, reducing the treatment of p...
