Detachable automatic sand adding sand tank, combined sand tank and realization method

Abstract

The invention discloses a detachable automatic sand adding sand tank, which mainly solves the problems of inconvenient transportation, high labor cost and low efficiency of sand adding operation and the like of the existing sand tank. The detachable automatic sand adding sand tank comprises a sand tank body, an automatic sand feeding mechanism, a conveyer and a motive power system, the sand tank body is formed by combining a base, a sand leaking tank and a sand storage tank which are in sequential detachable connection from bottom to top, the automatic sand feeding mechanism is arranged at the upper end of the sand storage tank, the conveyer is arranged in the base, is communicated with the sand leaking tank and is used for transporting sand, the motive power system provides motive power for the automatic sand feeding mechanism and the conveyor, the base, the sand leaking tank and the sand storage tank are respectively in a detachable structure, and a utility knife which is near the automatic sand feeding mechanism and is used for gashing sand bags is also arranged in the sand storage tank. The invention also provides a combined sand tank formed by two detachable automatic sand adding sand tanks and a realization method of the detachable automatic sand adding sand tank. The detachable automatic sand adding sand tank, the combined sand tank and the realization method have the advantages that the transport efficiency is high, the cost is low, and in addition, the automation degree and the construction efficiency are respectively much greater than those of the prior art.

Description

technical field [0001] The invention belongs to the field of oil and gas field development and fracturing, gas testing (oil) operation construction, and specifically relates to a detachable automatic sand tank, a combined sand tank and a realization method. Background technique [0002] At present, in oil and gas field fracturing and gas testing (oil) operations, sand fracturing is an important method. The sand tanks used in traditional sand adding are bulky and tall. It takes at least eleven vehicles to transport a sand tank to the construction site, which is not easy to disassemble and transport. In addition, the sand adding operation based on the traditional sand tank still has the following defects: [0003] 1. The degree of mechanical automation and sanding efficiency are low [0004] During the sand loading process, the crane operator is involved in the whole process, and the crane needs to hang the sand bag at the construction site for 24 hours. The work intensity ...

AI Technical Summary

Problems solved by technology

[0004] During the sand loading process, the crane operator is involved in the whole process, and the crane needs to hang the sand bag at the construction site for 24 hours. The work intensity is very high; the opening of the sand bag is completely manual operation, and at least two people (contractors) are required to use it on the top of the sand tank. The knife cuts the sand bag, and the labor cost is high;

[0005] Second, there are great security risks

[0006] The crane is located on the ground, and the crane operator is working on the ground. Its field of vision is narrow, and it is difficult to observe the condition of the contractor on the top of the sand tank.
