Foldable sand tank for oil/gas well fracturing

Abstract

The invention relates to the technical field of fracturing operation devices for oil-gas field development and discloses a foldable sand tank for oil / gas well fracturing. The foldable sand tank for oil / gas well fracturing comprises a top-layer sand storage tank body, a second-layer sand storage tank body and a sand leaking tank body which are sequentially and detachably connected from top to bottom, and the top-layer sand storage tank body, the second-layer sand storage tank body and the sand leaking tank body are each of a detachable structure. The problem that an existing sand tank is inconvenient to transport is solved. Compared with the prior art, the foldable sand tank for oil / gas well fracturing has the beneficial effects that 1, a tank body structure is detachable and convenient to transport and install, one sand tank can be transported just through two trucks, installation is completed within one day, and the cost of transportation and installation is greatly reduced; 2, the foldable sand tank achieves the dual functions of sand storage and continuous sand supply, and the highest sand discharging speed reaches 8 m<3> / min; and 3, a special sand breaker and a fence are installed on the top of the foldable tank, sand breaking is achieved without manual assistance by people, and the safety risk is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development fracturing operation devices, in particular to a foldable sand tank used for fracturing oil and gas wells. Background technique [0002] In the field of oil and gas field development, low-permeability oil and gas fields, especially shale gas fields, are generally exploited by fracturing to achieve economical and effective development of low-permeability reservoirs. Fracturing is to use the surface high-pressure pump group to pump fracturing fluid into the wellbore to hold up the high pressure to rupture the reservoir, and continue to pump fracturing fluid through the wellbore to continue to extend the fractures formed in the reservoir, and at the same time, the proppant-carrying fractures will continue to extend. The fracturing fluid squeezes into the fractures formed by the reservoir to support the formed fractures, providing high-conductivity flow channels for oil and gas, ...
