Abstract
The utility model relates to a pipeline cleaning control device of a heavy oil pump, comprising a water-mixed pipe, a pressure reduction valve, a flow regulating valve and a water-mixed pump. The pipeline cleaning control device of the heavy oil pump is characterized in that one end of the water-mixed pipe is connected with an outlet of a waste water reinjection pump on a station, namely, an outlet of the water-mixed pump, and the other end thereof is connected with a connecting pipe between an inlet valve of the heavy oil pump and a filter; and a regulating valve and a pressure reduction valve are arranged in front of and behind the front end part of the water-mixed pipe. In the pipeline cleaning control device of the heavy oil pump, by the pressure reduction of the pressure reduction valve and the flow regulation of the flow regulating valve, high temperature waste water from the outlet of the waste water reinjection pump on the station enters the filter and the heavy oil pump, and then enters an oil heavy oil external delivery pipeline through the outlet valve of the heavy oil pump to dredge the filter, the heavy oil pump and pipelines and clean heavy oil by controlling the high-temperature high-pressure reinjection produced water; the pipeline cleaning control device of the heavy oil pump is time-saving and labor-saving, can recover crude oil and has no environmental pollution, and is accepted by field workers.
Description
One, technical field
The utility model relates to the thick oil pump cleaning pipeline purging control gear that a kind of viscous crude field heavy oil transportation is used.
Two, background technique
Viscous crude has high viscosity, high condensation point, the high bitum characteristics of high colloid, lead pump at the viscous crude output pump, when stopping transport maintenance and filter rinsed, because this moment, viscous crude remained static, the oil temperature sharply descends, cause crude oil to be set in the pump and filter in, must could overhaul crude oil washing/COW pump or change filter cartridge, because the viscosity of viscous crude is big, the high gum asphalt height of solidifying point, be difficult to clean, and make the full pumping room all to be crude oil, do the maintenance of a pump and want 8 hours time, waste time and energy, and the effect of the effect of inspection pump and cleaning filter is also undesirable.If run into unexpected power failure, power off time is long slightly, when restarting pump, incoming call just starts not, must be with the appearance heating of high-temperature-hot-water or steam towards pump and filter, the crude oil that solidifies has been dissolved could be pump startup, the crude oil solution time must need two hours time, influences the normal outer defeated of crude oil.
Three, summary of the invention
The purpose of this utility model provides a kind of thick oil pump and cleans the pipeline purging control gear, solves the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of water mixing pipe, reduction valve, flow control valve and water mixing pump, produced-water reinjection pump discharge on it is characterized in that water mixing Guan Yiduan and standing is that the water mixing pump discharge links to each other, the other end links to each other with connecting tube between thick oil pump inlet valve and the filter, is provided with a modulating valve and a reduction valve before and after water mixing pipe front end.
The high temperature sewage of produced-water reinjection pump discharge reduces pressure by reduction valve on the utility model utilization station, the Flow-rate adjustment of flow control valve, enter filter and thick oil pump, enter the viscous crude multi-purpose station pipeline by the thick oil pump outlet valve again, under control to the High Temperature High Pressure return water, the mediation filter, thick oil pump and pipeline, wash viscous crude, time saving and energy saving, accomplish that promptly crude oil recovery is also free from environmental pollution.This device is welcome by on-the-spot worker deeply.
Four, description of drawings
The on-the-spot mounting structure schematic representation of accompanying drawing-the utility model
1-water mixing pipe 2-thick oil pump inlet valve 3-reduction valve 4-flow control valve 5-filter 6-thick oil pump outlet valve 7-thick oil pump 8-produced-water reinjection pump among the figure
Five, embodiment:
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of water mixing pipe 1, reduction valve, flow control valve and water mixing pump, produced-water reinjection pump discharge on it is characterized in that water mixing Guan Yiduan and standing links to each other, the other end links to each other with connecting tube between thick oil pump inlet valve and the filter, is provided with a modulating valve and a reduction valve before and after water mixing pipe front end.
When using the utility model, at first utilize reduction valve 3 that the produced-water reinjection delivery side of pump is come the water pressure decompression, reduce to below the 10Mpa by the pressure of 15Mpa-20Mpa, be transferred to suitable flow through flow control valve 4 according to the size of thick oil pump lift again and enter filter 5 and thick oil pump 7, enter the viscous crude external transport pipeline through thick oil pump outlet valve 6, utilize 45-60 ° return water that flow process is dredged earlier, restarting thick oil pump washes, when treating that the thick oil pump lift reaches normal range (NR), filter and thick oil pump cleaning are finished.Shut reduction valve, can change the work of filter cartridge or maintenance pump.If cause that because of having a power failure suddenly thick oil pump starts not, defeated flow process directly starts thick oil pump outside can directly leading after cleaning, and enters the defeated work of normal viscous crude outward.
Claims (1)
1. a thick oil pump cleans the pipeline purging control gear, form by water mixing pipe, reduction valve, flow control valve and water mixing pump, produced-water reinjection pump discharge on it is characterized in that water mixing Guan Yiduan and standing is that the water mixing pump discharge links to each other, the other end links to each other with connecting tube between thick oil pump inlet valve and the filter, is provided with a modulating valve and a reduction valve before and after water mixing pipe front end.
