Abstract
The utility model relates to a pressure-stabilization liquid supply device for large fracturing construction, and belongs to the technical field of the large fracturing construction of wells in petroleum exploration and development. The pressure-stabilized liquid supply device comprises a liquid inlet pipeline, a centrifugal pump, a liquid outlet pipeline, a pressure sensor and a control box, wherein the inlet and the outlet of the centrifugal pump are communicated with the liquid inlet pipeline and the liquid outlet pipeline respectively; a hole is formed in the liquid outlet pipeline and the pressure sensor is mounted on the liquid outlet pipeline; a signal cable of the pressure sensor is connected to the control box; an output power cable of the control box is connected to the power supply end of the centrifugal pump. During construction, the control box outputs a control signal for adjusting the rotary speed of the centrifugal pump and controlling the output pressure to achieve continuous stable liquid supplying.
Description
technical field:
The utility model relates to a kind of massive hydraulic fracturing construction and uses voltage stabilizing liquid feed means, belongs to petroleum exploration and development well massive hydraulic fracturing technical field of construction.
background technique:
At present, in the construction of oil gas field massive hydraulic fracturing, need to use a large amount of liquid container deposit fracturing fluids, each liquid container is connected to major diameter feed flow manifold by pipeline.Because the distance difference between each liquid container and feed flow manifold is larger, cause in construction each liquid container fluid supply capacity difference large, cause each liquid container feed flow uneven, affect normal construction.
summary of the invention:
The purpose of this utility model is in order to overcome the defect that each liquid container feed flow that prior art exists is uneven, affect normal construction, a kind of massive hydraulic fracturing voltage stabilizing liquid feed means to be provided.
The utility model is comprised of feed liquor pipeline, centrifugal pump, fluid pipeline, pressure transducer, control box.The import and export of centrifugal pump are connected with fluid pipeline with feed liquor pipeline respectively, perforate setting pressure sensor on fluid pipeline, and the signal cable of pressure transducer is connected to control box, and the outputting power cable of control box is connected to centrifugal pump feeder ear.
The beneficial effects of the utility model are: under the complicated feed flow environment of massive hydraulic fracturing, export control signal centrifugal pump is carried out to rotational speed regulation by control box, control delivery pressure, realize and continue steady feed flow.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
embodiment:
The utility model is comprised of feed liquor pipeline 1, centrifugal pump 2, fluid pipeline 4, pressure transducer 3, control box 6.The import and export of centrifugal pump 2 are connected with fluid pipeline 4 with feed liquor pipeline 1 respectively, perforate setting pressure sensor 3 on fluid pipeline 4, and the signal cable of pressure transducer 3 is connected to control box 6, and the outputting power cable of control box 6 is connected to centrifugal pump 2 feeder ears.
Described centrifugal pump 2 and feed liquor pipeline 1 and fluid pipeline 4 are arranged on sled 5.
In pressing crack construction, feed liquor pipeline 1 is connected with feed flow manifold, fluid pipeline 4 is connected with fracturing blender truck, the pressure signal of the fluid pipeline 4 being gathered by 6 pairs of pressure transducers of control box 3 is processed, and export the motor speed of frequency control of motor speed Signal Regulation centrifugal pump 2, its delivery pressure is stabilized in setting value.When pressing crack construction discharge capacity uprises or during step-down, can cause that fluid pipeline 4 pressure change, by pressure transducer 3 testing signals, control control boxs 6 and automatically adjust motor speed and raise or reduce, keep fluid pipeline 4 pressure set points, realize stable and uniform feed flow.
