Abstract

The invention discloses a fracturing temporary plugging agent delivery device and a working method thereof.The fracturing temporary plugging agent delivery device comprises a delivery device body, a storage bin is arranged above the delivery device body, a thin neck part is formed at the bottom of the storage bin, a counter located in the storage bin is arranged in the thin neck part, a mechanical arm is arranged in the delivery device body, and the mechanical arm is connected with the storage bin. The mechanical arm is located below the thin neck part, and a check valve is arranged at one end of the mechanical arm. By the adoption of the fracturing temporary plugging agent delivery device, the temporary plugging ball is delivered from the low-pressure channel to the high-pressure channel in the delivery process, in the whole process, the two sealing mechanisms are switched according to the sequence of substitution, it is guaranteed that high-pressure liquid does not overflow or leak out, and safety of equipment and operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a fracturing temporary plugging agent delivery device. Background technique [0002] Fracturing is a commonly used stimulation measure in the development of oil and gas fields, especially in the development of low-permeability oil and gas reservoirs, fracturing must be carried out in order to obtain better results. [0003] During the construction process, on the basis of opening the cracks, it is necessary to put temporary plugging agent in the cracks or high-permeability layers to generate filter cake bridge plugging, so that the subsequent working fluid cannot enter, prompting new cracks to be opened again, new longitudinal layers to be opened, Plane crack turns. Due to the need to produce a high-strength filter cake layer, the strength of the granular temporary plugging agent is required to be high. If it is added from the sand mixing equipment, the gra...
