Large-displacement all-electric fracturing continuous sand supply device and method

Abstract

The invention relates to a large-displacement all-electric fracturing continuous sand supply device and method. The large-displacement all-electric fracturing continuous sand supply device comprises a vertical sand storage tank, a continuous sand supply device body and a control system device; the vertical sand storage tank is mounted on a platform base and consists of a tank body I, a tank body II, a conical bin, a base and a steel foundation; the continuous sand supply device body consists of a vertical sand hopper, a bucket elevator, a spiral conveyor and a bag breaking device; and the control system device is installed on one side of the tank body and is composed of an electric gate valve, an anti-explosion control box, a video monitoring system and the like. The large-displacement all-electric fracturing continuous sand supply device is developed and matched for achieving storage and continuous sand supply of fracturing propping agents in the unconventional shale gas electric fracturing construction period, sand conveying and storage of fracturing sand of different specifications can be met, and a square all-electric structure and a modular connection mode are adopted; and the electric gate valve is adopted to control the sand amount, continuous and automatic sand conveying can be achieved, sand conveying efficiency is high, operation is easy, accuracy is high, errors are small, safety and reliability are achieved, maintenance is convenient, and the device can be directly applied to field operation construction.

Description

technical field [0001] The invention relates to the technical field of shale gas exploitation, in particular to a large-displacement all-electric fracturing continuous sand supply device and method. Background technique [0002] The existing sand delivery method for shale gas fracturing mainly uses the method of adding sand in tons of bags directly from the ground to the top of the sand tank by cranes. The method of adding sand in tons of bags by cranes mainly uses traditional cranes to add sand, and the efficiency of sand addition is low. The degree of automation is low, the cost of human resources is high, and the risk of on-site hoisting at high places is high. The existing method has the following defects: poor accuracy and lack of quantitative evaluation; low efficiency and long time for adding sand; personnel working at high places, high risk of falling casualties. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention ...
