technical field

The utility model relates to an oil-water separation device, in particular to a novel oil-water separation device.

Background technique

As the oil content in the oilfield gradually decreases, today's oilfield oil recovery has entered the stage of enhanced oil recovery. The accompanying structure is that the water cut in the well oil is very high, even reaching a water cut of about 90%. Therefore, effective oil-water separation technology is very necessary.

The existing oil-water separation technologies mainly include physical sedimentation method, hydrocyclone method, chemical demulsifier demulsification method, semi-permeable membrane method, etc. Although physical settlement is effective, it takes too long and the efficiency is extremely low, and it cannot complete dynamic continuous work; the hydraulic cyclone adopts the principle of centrifugal separation, and generates strong centrifugal force through rotation to separate oil and water. The hydrocyclone used in the project occupies a large area. The cost is high, and it is not easy to maintain; the chemical demulsifier method needs to add chemical demulsifiers to the emulsion, and the demulsifiers that cannot be separated will be broken and remain in the water, resulting in pollution of water sources, which violates the principle of green environmental protection; the semi-permeable membrane method is suitable for large-scale Small oil-water separation reduces separation efficiency.

Utility model content

The utility model aims to solve the above problems, and provides an energy-saving, environment-friendly and highly efficient oil-water separation device, which has the advantages of simple structure, economy and environment protection, high separation efficiency, strong stability, and long service life, and is especially suitable for oil production in oil fields entering high water-cut periods. coarse separation. The technical scheme adopted is as follows:

A new type of oil-water separation device, including pure water inlet A, oil-water inlet A, oil-water inlet B, oil-water inlet C, pure water inlet B, pure water outlet A, oil-water outlet, pure water outlet B, primary fusion zone, primary demulsification area, arched area, primary separation area, secondary fusion demulsification area, secondary fusion area, and secondary separation area. The pure water inlet A is connected in parallel with the oil-water inlet A, and is vertically connected with the oil-water inlet B. After the water inlet A, the primary fusion zone, the primary demulsification zone and the arched area are set in sequence. After the arched area is the primary separation zone, which is connected to the pure water outlet B. The pure water outlet A and the oil-water outlet are separated. The secondary separation zone is set, the secondary fusion zone is set at the oil-water inlet C, and the secondary fusion demulsification zone is set at the pure water inlet B.

The height of the arched area in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet A in the y direction. The height of the pure water inlet 5 in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet 4 in the y direction.

The height of the pure water inlet B in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet C in the y direction.

Beneficial effects: an energy-saving, environmentally friendly and efficient oil-water separation device, through the arrangement of the area in the pipe, the oil droplets can be smoothly fused and flow out from the predetermined outlet with a high concentration, and it is not easy to damage, achieving reliability; it is completely separated by physical methods, without The use of any tidbit demulsifier can achieve green environmental protection; it has the advantages of simple structure, economical and environmental protection, high separation efficiency, strong stability and long service life, especially suitable for rough separation of well oil in oil fields entering high water cut period.

detailed description

Below in conjunction with accompanying drawing and example the utility model is described further:

As shown in Figure 1, a new oil-water separation device includes pure water inlet A1, oil-water inlet A2, oil-water inlet B3, oil-water inlet C4, pure water inlet B5, pure water outlet A6, oil-water outlet 7, pure water outlet B8, Primary fusion zone 9, primary demulsification zone 10, arched zone 11, primary separation zone 12, secondary fusion demulsification zone 13, secondary fusion zone 14, secondary separation zone 15, the pure water inlet A1 and oil-water The inlet A2 is connected in parallel and vertically with the oil-water inlet B3. After the pure water inlet A1, the primary fusion zone 9, the preliminary demulsification zone 10 and the arched zone 11 are set in sequence. After the arched zone 11 is the primary separation zone 12, the primary separation zone 12 is connected to the pure water outlet B8, the secondary separation zone 15 is set between the pure water outlet A6 and the oil-water outlet 7, the secondary fusion zone 14 is set at the oil-water inlet C4, and the secondary fusion demulsification zone 13 is set in the pure water Entrance B5.

The height of the arched area 11 in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet A2 in the y direction. The height of the pure water inlet 55 in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet 44 in the y direction.

The height of the pure water inlet B5 in the y direction should be slightly higher than the height of the upper edge of the oil-water inlet C4 in the y direction.

Working process: When working, the oil-water mixture entering from the oil-water inlet A2 and the oil-water inlet B3 is fused in the primary fusion zone 9, and the primary demulsification is achieved in the preliminary demulsification zone 10 under the extrusion of the high-speed water flowing in from the pure water inlet A1. Milk, the oil droplets flowing out from the primary demulsification zone 10 then flow through the arched zone 11 to accelerate, and flow in the y direction in the primary separation zone 12, and a part of water flows out from the pure water outlet B8 at a relatively high flow rate; primary separation The remaining oil continues to pass through the secondary fusion and demulsification zone 13, where the flow velocity is reduced and the oil gathers temporarily to realize fusion and demulsification. Then the oil passes through the secondary fusion zone 14, its mechanism is similar to that of the primary fusion zone 9, and the oil droplets gather and fuse in this zone; then the oil droplets flow through the secondary separation zone 15 and flow away to the positive direction of x, and a part of water flows from x The pure water outlet A6 in the negative direction flows away, while all the oil droplets flow out from the oil-water outlet 7 to complete the entire separation process, so that the volume fraction of oil droplets flowing out of the oil-water outlet 7 can be greatly increased.
