Problems solved by technology
There are following deficiencies in this traditional method: 1, need multi-level settlement, so cause base station or united station (the oil of several base stations is transported to a centralized processing unit to be referred to as united station) facility and place are huge; 2, increase transportation Cost; 3. The most important thing is that the added demulsifier will make the crude oil contain demulsifier components, which will affect the quality of the refined oil

Embodiment Construction
[0017] Please check figure 1 , an electroacupuncture demulsification device for oil-water separation of crude oil, including a container 10, an electrode group module 20, a power supply 30, a floating oil collection port and an oil bubble defoamer.
[0018] The container 10 may include an airtight casing and a casing bracket for fixing the reinforced casing. The container 10 is a closed container, and the container 10 is provided with a liquid inlet 11, a liquid outlet 12 and an air outlet 13, and the liquid inlet 11 is located at the bottom of the container 10, such as the bottom wall of the container, the liquid outlet 12 and the gas outlet 13. The air outlet 13 is arranged at intervals on the top of the container 10, such as the top wall of the container, and the liquid outlet 12 constitutes the oil slick collection port, or the liquid outlet 12 and the air outlet 13 together form the oil slick collection port. In this embodiment, there are also oil well production pipelin...

The invention discloses an electric-needle demulsifying device for crude oil and water separation. The electric-needle demulsifying device for the crude oil and water separation comprises a container, electrode group modules and a power supply, wherein each electrode group module is inserted into a produced oilfield fluid in the container and is provided with two electrodes, and the electrodes include a titanium-based and surface-ceramized modified oxidized electrode and a titanium-based and surface-modified graphite electrode; the produced oilfield fluid in the container forms an electrolyte, the power supply enables the electrode group modules to produce current, and when the current runs through the produced oilfield fluid, due to non-uniform distribution of the resistance values of emulsified beads, the current is forced to be conducted between the surface of one bead and the surface of another bead; under the factor action of a non-good conductor, friction is formed to cause an attractive or repulsive reaction between the beads, and under the action of the voltage of the two electrodes, the current is forced to be conducted between the surface membranes of the beads to form an electric-needle action, so that rupture of the surface membranes of the beads is promoted to achieve demulsification. The electric-needle demulsifying device for the crude oil and water separation has the advantages as follows: demulsification and oil and water separation can be achieved within a short time, a chemical demulsifying agent is not required to be used, and crude oil does not contain a chemical demulsifying agent component.
Description
technical field [0001] The invention relates to an oil-water separation device, in particular to an electroacupuncture demulsification device for crude oil-water separation. Background technique [0002] Oilfield production fluid is a mixture of crude oil and formation water, and the ratio of oil to water in each block of an oil well is different. The moisture and crude oil in the oilfield production fluid are affected by the change of formation pressure and various factors of production. Oil and water exist in the form of emulsification, that is, the emulsification form of oil in water and water in oil. The oil-water liquid in the emulsified form must be separated from oil and water before it can be transported to the refinery for refining. The traditional method adopts gravity sedimentation method for dehydration and chemical agent method for demulsification, that is, oil well production fluid is added with chemical demulsifier at the base station (primary unit for centra...
