Description

Technical Field

[0001] This invention relates to the field of crude oil extraction technology, specifically to an integrated intelligent high-pressure injection device for oil and water wells. Background Technology

[0002] A skid-mounted unit refers to a group of equipment fixed to a chassis made of angle steel or I-beams, which can be moved and positioned using pry bars. This group of equipment is exposed, unlike a pressure regulating box. Many other skid-mounted units exist, such as skid-mounted generator sets, skid-mounted air compressors, and heat exchanger units. Skid-mounted also refers to a pre-installed, integrated assembly of valves, pumps, and other equipment, eliminating the need for additional valves, instruments, or other equipment in the intermediate stages when connecting to other equipment in the system. Connections are simply made via pipelines. Skid-mounted is a form of integrated equipment frame and overall equipment assembly.

[0003] During crude oil extraction, various liquid chemicals, including demulsifiers, viscosity reducers, wax removers, and corrosion inhibitors, need to be added to the wellbore or to the produced fluid and injection medium. The type and quantity of liquid chemicals added are determined based on the properties of the produced fluid or injection medium and the requirements of the treatment process. To facilitate the addition of liquid chemicals, a dosing device is generally installed at the wellhead. Dosing devices are suitable for locations with concentrated oil and gas production and can provide long-term, stable addition of liquid chemicals.

[0004] Existing high-pressure injection equipment typically uses a fixed drug preparation tank with a fixed drug flow rate. When mixing different materials or pressure / flow combinations, it may face problems such as low mixing efficiency or uneven mixing. Moreover, if the mixture is not used in time after being mixed by the high-pressure injection equipment, sedimentation or gelation may occur. Summary of the Invention

[0015] This invention provides an integrated intelligent high-pressure injection device for oil and water wells. It has the following beneficial effects:

[0016] 1. This invention uses a fixed rod, a rotating wheel, and a water tank to initially mix the medicine and liquid. Then, the initially mixed liquid is sent to the first mixing tube through a pressurizing pipe. The liquid is separated by impacting the baffle through the pressurizing pipe. The liquid is then mixed again in the pressurizing pipe. The liquid is then mixed again by the baffles and blocks in the second and third mixing tubes.

The output end of the push rod motor moves upward, driving the connecting part to move upward. Through the rotating part, the triangular plate slides in the tank, so that the four triangular plates form a cone shape. Then, the output end of the push rod motor moves back and forth for a certain period of time, thereby avoiding liquid sedimentation in the first and second tanks. Steel plates are welded to the four corners of the tank to form an arc shape to prevent the injected material from being stirred and deposited. Attached Figure Description

[0036] Turn on the water pump 15, which sends the liquid into the housing 20. Then, turn on the medicine tank 12 and send the liquid into the housing 20 through the medicine outlet pipe 17. The medicine and liquid are initially mixed by the fixed rod 44, the rotating wheel 45 and the water tank 46. Then, the initially mixed liquid is sent to the first mixing pipe 22 through the pressure boosting pipe 21. The liquid is separated by impacting the baffle 47 through the pressure boosting pipe 21. Then, it is mixed again in the pressure boosting pipe 21. The liquid is mixed again by the baffle 47 and the stop block 48 in the second mixing pipe 23 and the third mixing pipe 24. After mixing, the liquid enters the first tank 4 and the second tank 11. Then, the drive motor 6 makes the liquid and medicine mix evenly.

[0044] Stop the pump and close the valve

[0045] When tank No. 1 reaches the high liquid level, the water supply pump will automatically stop and the water supply valve for tank No. 1 will be closed.

[0046] When tank No. 2 reaches the high liquid level, the water supply pump will automatically stop and the water supply valve for tank No. 2 will be closed.

[0047] When tanks 1 and 2 reach high liquid levels simultaneously, the water supply pump will automatically stop, and the water supply valves for tanks 1 and 2 will be closed.

[0048] Open valve, start pump

[0049] When the liquid level in tank No. 1 is low, the water supply valve for tank No. 1 will automatically open and the water supply pump will start.

[0050] When the liquid level in tank No. 2 is low, the water supply valve for tank No. 2 will automatically open and the water supply pump will start.

[0051] If water replenishment is required, tank #1 should be prioritized.

[0052] 2) Dosing pump and dosing valve

[0053] Two dosing valve switches control the dosing pump to circulate dosing between two tanks.

[0054] Stop the pump and close the valve

[0055] The dosing pump automatically shuts off after running for a certain period of time (in seconds) each time it starts; the duration can be set via the touchscreen.

[0056] Automatic valve shut-off after pump stop

[0057] Open valve, start pump

[0058] When the liquid level in tank No. 1 rises from the low level to 50% of the high level, the dosing valve in tank No. 1 will automatically open and the dosing pump will start (the dosing valve must be opened first, then the dosing pump will start; the dosing pump must not be started if the dosing valve is not opened). (When the liquid level drops from the high level to 50% of the high level, neither the dosing valve nor the dosing pump should be opened).

[0059] When the liquid level in tank No. 2 rises from the low level to 50% of the high level, the dosing valve in tank No. 2 will automatically open and the dosing pump will start (open the dosing valve first, then start the dosing pump; the dosing pump must not be started if the dosing valve is not open). (When the liquid level drops from the high level to 50% of the high level, neither the dosing valve nor the dosing pump should be opened).

[0060] If additional medication is required, tank #1 should be prioritized.

[0061] 3) Mixer

[0062] start up

[0063] When starting with one button, the agitator motor of tank 1 will automatically start when the liquid level rises from the low level to 50% of the high level; the agitator motor of tank 2 will automatically start when the liquid level rises from the low level to 50% of the high level.

[0064] stop

[0065] When the liquid level in tank 1 reaches the low level, the stirring motor in tank 1 stops running; when the liquid level in tank 2 reaches the low level, the stirring motor in tank 2 stops running.

[0066] 4) Plunger pump

[0067] start up

[0068] Once the liquid level in Tank No. 1 reaches the high level, the electric butterfly valve at the outlet of Tank No. 1 will open, and the plunger pump will be started.

[0069] stop

[0070] The plunger pump automatically stops when the pressure is higher than the set value; the plunger pump automatically stops when the pressure is lower than the set value; the plunger pump stops when tanks 1 and 2 are both at low liquid levels.

[0071] 5) Outlet electric butterfly valve

[0072] When the liquid level in tank 1 is low, the electric butterfly valve at outlet 1 will automatically close, and the electric butterfly valve at outlet 2 will automatically open. (The electric butterfly valve at outlet 2 will only open when tank 2 is at a high liquid level. If tank 1 is at a low liquid level and tank 2 has not yet reached a high liquid level, the plunger pump will stop running until tank 2 continues to accumulate water to a high liquid level.)

[0073] When the liquid level in tank 2 is low, the electric butterfly valve at outlet 2 will automatically close, and the electric butterfly valve at outlet 1 will automatically open. (The electric butterfly valve at outlet 1 will only open when tank 1 is at a high liquid level. If tank 2 is at a low liquid level and tank 1 has not yet reached a high liquid level, the plunger pump will stop running until tank 1 continues to accumulate water to a high liquid level.)

[0074] When tanks 1 and 2 are both at low liquid levels, the plunger pump must not be started. At the same time, the electric butterfly valves at the outlets of tanks 1 and 2 should be closed until tank 1 is filled to a high liquid level. Then, the electric butterfly valve at the outlet of tank 2 should remain closed, the electric butterfly valve at the outlet of tank 1 should be opened, and then the plunger pump should be started.
