Abstract
The utility model provides an anti-scaling valve bank of a post-filter. Relates to the technical field of oilfield flooding. The inlet tube gets into the water diversion jar from the cylinder middle part of water diversion jar, all installs the ultrasonic wave descaler on the end enclosure at water diversion jar both ends, divides a plurality of water injection pipeline of water diversion jar lower part parallelly connected, all installs motorised valve, flowmeter, Y type filter and trip valve on every water injection pipeline. The utility model has the following beneficial effects: the dirt in the water distribution cylinder is vibrated to fall off by the ultrasonic descaling instrument, the dirt is intercepted by the Y-shaped filter installed at the bottom, the dirt is prevented from entering the stratum to influence the water injection quality, the two Y-shaped filters installed in parallel can be switched to be used, the water injection does not need to be stopped when the filter element of the Y-shaped filter is cleaned, and the operation efficiency of the water injection operation is improved.
Description
The technical field is as follows:
the utility model relates to the technical field of oilfield water injection, in particular to a post-filter anti-scale valve bank.
Background art:
when water is injected into an oil field, a centralized water injection mode is provided, high-pressure water is boosted by a high-pressure pump through a water inlet pipe and enters a water distribution cylinder, the water distribution cylinder is distributed into each single well through a water injection pipeline and a valve group, when the high-pressure water flows into the water distribution cylinder and the water distribution cylinder is distributed to each water injection pipeline, water flow changes the flow direction for many times, water impact causes the increase of the trend of scaling in the water distribution cylinder, and scale substances in the water distribution cylinder enter the water injection pipeline after falling off, so that the water injection quality is reduced.
The utility model has the following contents:
the utility model provides an anti-scaling valve bank of a post-filter, aiming at solving the problem of water injection quality reduction caused by scaling of a water distribution cylinder.
The technical scheme of the utility model is as follows: the utility model provides a rearmounted filter anti fouling valves, includes the inlet tube, and the inlet tube gets into the water distribution cylinder from the cylinder middle part of water distribution cylinder, all installs ultrasonic wave scale removal appearance on the end closure at water distribution cylinder both ends, and a plurality of water injection pipeline of water distribution cylinder lower part parallel connection all install motorised valve, flowmeter, Y type filter and trip valve on every water injection pipeline.
Two Y-shaped filters are connected in parallel on each water injection pipeline, and a cut-off valve is installed at the front and the rear of each Y-shaped filter.
One Y-shaped filter is arranged on a main pipeline which passes through linearly, and the other Y-shaped filter is arranged on a bypass pipeline.
The bypass pipeline is connected with the main pipeline through four 45-degree elbows.
The utility model has the following beneficial effects: dirt in the water distribution cylinder is vibrated to fall off through the ultrasonic descaling instrument, the dirt is intercepted by the Y-type filter installed at the bottom, the dirt is prevented from entering the stratum to influence the water injection quality, the Y-type filters installed in parallel can be switched to be used, water injection is not required to be stopped during cleaning of the filter element of the Y-type filter, the operation efficiency of water injection operation is improved, the main pipeline through which straight lines pass is normally open, the bypass pipeline serves as a standby pipeline, the Y-type filter on the main pipeline is cleaned, the stop valve of the bypass pipeline is opened, high-pressure water flows through the bypass pipeline, the stop valve on the main pipeline is closed, the stop valve of the main pipeline is opened again after cleaning of the filter element of the Y-type filter on the main pipeline, the flow direction of high-pressure water is changed as far as possible, the pipeline resistance is reduced, and the scaling tendency of the water injection pipeline is reduced.
Description of the drawings:
FIG. 1 is a schematic diagram of the present invention.
In the figure, 1-a water inlet pipe, 2-a water distribution cylinder, 3-an ultrasonic descaler, 4-a water injection pipeline, 5-an electric valve, 6-a flowmeter, 7-a Y-type filter, 8-a bypass pipeline and 9-a main pipeline.
The specific implementation mode is as follows:
the utility model will be further described with reference to the accompanying drawings in which:
shown by figure 1, a rearmounted filter scale control valves, including inlet tube 1, inlet tube 1 gets into branch jar 2 from the cylinder middle part of branch jar 2, all install ultrasonic wave descaler 3 on the head at branch jar 2 both ends, divide 2 parallelly connected a plurality of water injection pipeline 4 in jar lower part, all install motorised valve 5 on every water injection pipeline 4, flowmeter 6, Y type filter 7 and trip valve, shake the dirt matter in the branch jar 2 through ultrasonic wave descaler 3 and drop, utilize the Y type filter 7 of undermost installation to intercept the dirt matter, avoid the dirt matter to get into the stratum and influence the water injection quality.
Two parallelly connected Y type filters 7 on every water injection pipeline 4, the trip valve is all installed around every Y type filter 7, and two parallelly connected Y type filters 7 of installing can switch over the use, need not to stop the water injection during clearance Y type filter 7's filter core, improve water injection operation operating efficiency.
One Y-shaped filter 7 is arranged on a main pipeline 9 which passes in a straight line, and the other Y-shaped filter 7 is arranged on a bypass pipeline 8.
Main pipeline 9 is connected through four 45 elbows to by-pass pipeline 8, reduce the resistance when the high pressure water flows through by-pass pipeline 8, when daily use, main pipeline 9 that the straight line passes through is always logical, by-pass pipeline 8 is as the spare pipe, when needing to clear up Y type filter 7 on main pipeline 9, open by-pass pipeline 8's trip valve, the high pressure water flows through from by-pass pipeline 8, close the trip valve on main pipeline 9, open main pipeline 9's trip valve again behind the filter core of Y type filter 7 on the clearance main pipeline 9, the high pressure water of minimizing changes the flow direction, reduce the pipeline resistance, reduce the trend of 4 encrustations of water injection pipeline.
