Equipment for conveying propping agents

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...

AI Technical Summary

Problems solved by technology

However, the length of the horizontal sand tank is more than ten meters. When it is placed, it occupies a large volume. Therefore, in order to save the installation space, many vertical sand tanks have appeared. However, the feeding port of the vertical sand tank is relatively high, and it is difficult to use a sand tank truck Delivers proppant into vertical sand tanks with a certain height, thus limiting the use of vertical sand tanks
