The technical scheme that the utility model adopts is:
A kind of proppant loops back conveying device, being arranged on proppant circulation pumps between device and sand hopper, described proppant loops back conveying device and comprises conduit and power transmitting assembly, described conduit comprises the top conduit connected successively, intermediate conductor and below conduit, described top catheter proximal end connects proppant circulation and pumps device, the corresponding sand hopper upper opening of below catheter tip, intermediate conductor is horizontally disposed with, inside is provided with power transmitting assembly, top conduit and below conduit are separately positioned on the two ends of intermediate conductor, top conduit is upwards outward-dipping, its inclination angle relative to horizontal direction is 30-50 °.
Described below conduit is downwardly towards outer incline, and its inclination angle relative to horizontal direction is 40 °.
Described power transmitting assembly comprises motor, rotating shaft and helical blade, and described motor is arranged on one end of intermediate conductor, electric machine main shaft connects with rotating shaft, rotating shaft is provided with some groups of helical blades.
The beneficial effect that the utility model produces is:
Proppant of the present utility model loops back conveying device, in pulsed sand fracturing process, when fracturing blender truck is at the pure fracturing fluid of infusion, proppant can feed back in the sand hopper of fracturing blender truck bottom by the utility model fast, the object that the Rapid Circulation reaching proppant feeds back, contributes to the enforcement improving pulse fracturing technology.
The utility model has the following advantages compared with the external mode adopting a whole set of special equipment to carry out pulsed sand fracturing:
(1) apparatus structure is comparatively succinct, and cost is low.
(2) circulation that the mode be combined with gravity auxiliary phase by power transmission carries out proppant feeds back, and ompetence is strong.
(3) can with existing fracturing blender truck with the use of, change can not be caused to existing equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this patent is further described.
Fig. 1 is the structural representation that proppant of the present utility model loops back conveying device.
Number in the figure represents: below 1-flange, 2-motor, 3-, above conduit, 4-, device is pumped in conduit, 5-flange, 6-rotating shaft, 7-helical blade, 8-intermediate conductor, a-sand hopper, the circulation of b-proppant.
Detailed description of the invention
As shown in Figure 1, the utility model is that a kind of proppant loops back conveying device, is arranged on proppant circulation and pumps between device b and sand hopper a.Proppant loops back conveying device and comprises conduit and power transmitting assembly, described conduit comprises the top conduit 4, intermediate conductor 8 and the below conduit 3 that connect successively, concrete: top conduit 4 front end connects the upper opening that device b, the corresponding sand hopper a of below conduit 3 end are pumped in proppant circulation, dock with the sand hopper a of fracturing blender truck bottom by below conduit 3, thus form the feedback passage of proppant.
Top conduit 4 and below conduit 3 are separately positioned on the two ends of intermediate conductor 8, and top conduit 4 upwards outward-dipping, its inclination angle relative to horizontal direction is 30-50 °.Below conduit 3 is downwardly towards outer incline, and its inclination angle relative to horizontal direction is 40 °.Top conduit 4 and below conduit 3 form gravity auxiliary transmission mechanism of the present utility model, and inclination angle, below conduit 3 that top conduit 4 is designed to 30-50 ° are designed to the inclination angle of 40 °, are convenient to the quick release of proppant gravitional force.
Intermediate conductor 8 is horizontally disposed with, inside is provided with power transmitting assembly, and power transmitting assembly comprises motor 2, rotating shaft 6 and helical blade 7.Wherein: motor 2 is arranged on one end of intermediate conductor 8, the main shaft of motor 2 and rotating shaft 6 is coupled to each other, synchronous axial system, rotating shaft 6 is provided with some groups of helical blades 7.Above-mentioned parts in intermediate conductor 8, form the screw conveyer that motor 2 drives, reach the object of lateral transfer proppant.
In this detailed description of the invention, the front end of top conduit 4 is provided with flange 5, circulates pump device b and be connected with proppant.Intermediate conductor 8 one end is provided with flange, for connecting motor 2.
Using method of the present utility model is as follows:
Before pulsed sand fracturing construction, utilize the flange 5 of this device and proppant to circulate to pump device b and be connected, and below conduit 3 is docked with fracturing blender truck bottom sand hopper a, thus set up proppant feedback passage.Further, the rotating speed carrying out motor 2 according to the maximum sand concentration of pressure break infusion program is arranged, thus controls proppant lateral transport speed, meets the efficiency requirements that proppant feeds back, avoids the accumulation of proppant in screw conveyer.
Specifically when carrying out pulsed sand fracturing infusion pure fracturing fluid stage:
First, proppant enters into circulation by top conduit 4 and feeds back control device;
Then, the lateral transport of proppant is realized by the screw conveyer in intermediate conductor 8;
Finally, proppant enters into below conduit 3(and gravity auxiliary transmission mechanism), flow under gravity in the sand hopper a of bottom.
Pass through the utility model, when proppant flow is to feedback passage, under power transmission and gravity assist acting in conjunction, realize the feedback of proppant from fracturing blender truck top sand export (proppant circulation pump device b) lower portion sand hopper a, avoid the accumulation of proppant in transfer passage or spilling.
