Description
Technical field
The utility model relates to a kind of down-hole to carry out pressure break to coal entity and causes crack, then proppant is injected the device in crack.
Background technology
Coal is heterogeneous material, inner containing the defect such as microfissure, hole.Owing to limiting by the condition such as geological conditions, buried depth, the gas permeability difference of coal body is very large, and gas pumping is the necessary means of current projecting mine, highly gassy mine safety in production.At present, the Main Means that highly gassy mine, projecting mine down-hole draw out methane is by drilling take out in advance developing, driving face, then by pump group, with high negative pressure, the gas dissociated in coal seam is released, but for coal body store a large amount of adsorption gas but because gas permeability of coal seam difference can not effectively be released.Therefore, be necessary to adopt more Test Research to improve gas drainage results in down-hole by the method changing gas permeability of coal seam.
Summary of the invention
The utility model object is the deficiency for overcoming above-mentioned prior art, provides a kind of mine water sand fracturing device improving gas permeability of coal seam, improve gas drainage under suction effect.
The utility model comprises fracturing pump, puddle mixer, sand tank, water tank, power distribution cabinet, phase shifting transformer; All be connected by cable between phase shifting transformer with power distribution cabinet, between power distribution cabinet with fracturing pump, between power distribution cabinet with puddle mixer; Water tank is equipped with valve and pipeline interface, is connected by feed flow pipeline between water tank with puddle mixer, between puddle mixer with fracturing pump; Water tank is also connected with underground site water source by feed flow pipeline; Fracturing pump is connected with working site by high pressure line, after sand tank is placed in puddle mixer, to puddle mixer supply proppant.Store pressure sand in sand tank, pressure sand is made up of the proppant of different size.
The maximum pressure of fracturing pump is 45 MP, and maximum stream flow is 90 m3/h, and power of motor is 355 KW.Equipment can carry out colliery fracturing and the sand fracturing construction of maximum pressure 45MPa.Major function realizes fracturing and sand fracturing.Drive work by motor, the rotating speed of conversion fracturing pump can be controlled to adjust operating pressure and discharge capacity.Fracturing pump can one be used alone, also can be several and in parallel to use.
It is 0.2 ~ 0.9 MP that the liquid medium of puddle mixer exports maximum pressure, and flow is 45 m3/h, and power of motor is 315 KW.Major function carries out of the fracturing fluid preparation and conveying, driven by motor, can come compounding ratio and the output operation of controlling and adjustment construction medium according to the running parameter of data display; Also can recording parameters data for the analysis after fulfiling assignment and inspection.
Water tank volume is 6m
3.Major function stores water source.Power distribution cabinet major function is the startup, stopping, speed change etc. that control various equipment, meets the requirement of explosion proof of down-hole.Phase shifting transformer is the power input voltage 10kv/1.14kv of explosion-proof transformer, equipment use voltage 330v.Major function is that solution equipment becomes distribution.
The utility model can by fracturing fluid by high-pressure pump group to substantially exceed in the discharge capacity injection hole of formation absorption ability, partial high pressure is formed at the bottom of hole, and exceed the clossing pressure of drill hole and the tensile strength of rock, broken in coal seam, form crack, and then by load fluid, proppant is taken in crack, make the crack pressed off can under the supporting role of proppant, be unlikely closed, obviously can improve gas permeability of coal seam, improve gas drainage under suction time and gas drainage results.
Accompanying drawing explanation
Fig. 1 is the utility model anatomical connectivity schematic diagram.
Detailed description of the invention
All be connected by cable 7 between phase shifting transformer 6 with power distribution cabinet 5, between power distribution cabinet 5 with fracturing pump 1, between power distribution cabinet 5 with puddle mixer 2; Water tank is equipped with valve and pipeline interface, is connected by feed flow pipeline 8 between water tank 4 with puddle mixer 2, between puddle mixer 2 with fracturing pump 1; Water tank 3 is also connected with underground site water source by feed flow pipeline 8; Fracturing pump 1 is connected with working site fracture well head by high pressure line 9, after sand tank 3 is placed in puddle mixer 2, supplies proppant to puddle mixer 2.
