Embodiment Construction

[0029] The object of the present invention is to provide a device for transporting proppant, which can conveniently transport proppant to a vertical sand tank with a certain height.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] see Figure 1-Figure 3 , the equipment for transporting proppant provided by the embodiment of the present invention includes a transition storage tank 2, a star unloader 3, a sending tank 6, a delivery pipeline 5, a fan 8 and a first driving device, wherein the transition...

Abstract

The invention discloses equipment for conveying propping agents. The equipment comprises a transition storage tank, a star discharger, a sending tank, a conveying pipeline, a fan and a first driving device, wherein the transition storage tank is provided with a feeding opening and a discharging opening; the star discharger is provided with a feeding opening and a discharging opening, and in addition, the feeding opening of the star discharger is communicated with the discharging opening of the transition storage tank; the sending tank is provided with a feeding opening and a discharging opening, and in addition, the feeding opening of the sending tank is communicated with the discharging opening of the star discharger; the inside of the conveying pipeline is communicated with the discharging opening of the sending tank through a connecting pipeline, and in addition, a discharging valve is connected in series onto the connecting pipeline; the fan is arranged at on end of the conveying pipeline; and the first driving device drives the fan to rotate. The equipment has the advantages that the propping agents are sent into a vertical sand tank with a certain height by using the flow rate and the pressure generated by the fan; the scheme of only communicating one end of the conveying pipeline with the vertical sand tank and setting the positions of the sending tank and the transition storage tank to be lower can be adopted, so the propping agents can be conveyed into the transition storage tank; and further, the propping agents can be conveniently conveyed into the vertical sand tank.

Description

technical field [0001] The invention relates to the field of oil field technology, and more specifically relates to a device for transporting proppant. Background technique [0002] Fracturing refers to a method that uses hydraulic action to form cracks in oil and gas layers during the process of oil or gas recovery, also known as hydraulic fracturing. During the fracturing process of oil and gas layers, fracturing trucks are generally used to squeeze high-pressure, large-displacement, and certain-viscosity liquid into the oil layer. After the oil layer is pressed out into many cracks, proppant (such as quartz sand, etc.) is added to fill the cracks to increase oil and gas. The permeability of the layer to increase water injection or oil production. [0003] At present, domestic fracturing proppants are mainly stored in bags for easy transportation, and horizontal sand tanks are generally used for storage at fracturing sites. When in use, use a bag breaker to break the bag...
