Problems solved by technology

With the rapid increase in the amount of proppant used on the construction site and the increase in storage tank capacity, the storage tank is developing into a vertical storage tank with a small footprint, large capacity, and high height, which brings about an increase in the difficulty of hoisting large bags, There are many problems such as the decline of operating efficiency and the safety of operators

Abstract

The invention relates to a positive-pressure pneumatic conveying skid for an oilfield fracturing propping agent. The positive-pressure pneumatic conveying skid for the oilfield fracturing propping agent comprises a skid frame and is characterized in that a fan power-driven system, a gas channel and sand conveying system, a delivery tank assembly, movable feeding devices and an electric control system are arranged on the skid frame. The positive-pressure pneumatic conveying skid for the oilfield fracturing propping agent has the benefits as follows: the occupied area is small, the transportation is convenient, the operation environment and the operation safety are improved, and the efficiency of operation for conveying a material to a high storage tank is improved.

Description

technical field [0001] The invention relates to supporting equipment for oilfield fracturing, in particular to a positive pressure pneumatic conveying skid for oilfield fracturing proppant. Background technique [0002] Fracturing is the main measure to increase production in oil and gas fields. At present, domestic and foreign fracturing operations, especially shale gas fracturing construction sites, require a large amount of fracturing proppant. At present, in the process of fracturing construction, especially in areas with limited operating areas (such as mountainous areas), a large number of fracturing proppants are transported to the construction site in the form of ton bags, and then the ton bags are hoisted to the construction site by cranes. In the on-site proppant storage tank, the "big bag" mentioned here is a special container. With the rapid increase in the amount of proppant used on the construction site and the increase in storage tank capacity, the storage ta...
