Description
Technical Field
The utility model relates to an assembly type structure field especially relates to an oil gas field fracturing is with stifled piece of temporary storage and delivery device.
Background
Temporary plugging operations are an important stage in fracturing operations of oil and gas fields and are usually realized by putting temporary plugging balls or temporary plugging agents. However, some low-temperature water-soluble temporary plugging balls suitable for low-temperature wells are easy to be sticky or dissolved when entering water, and are difficult to be thrown into a ball throwing device filled with water, so that construction accidents are caused. In addition, with the development of temporary plugging technology, knotted temporary plugging is also receiving increasing attention. If the rope knot type temporary plug is directly thrown by the ball thrower, the rope knot type temporary plug is irregular in structure and easy to clamp in the ball thrower, so that the rope knot type temporary plug is usually wrapped by two hemispherical spherical shells in actual use and then thrown by the ball thrower. For a rope knot type temporary plug, once it leaves the pitching device and goes down the well, the coated "ball shell" opens as fast as possible, so theoretically the dissolution rate of the ball shell in water is as fast as possible. Due to the process requirements, the temporary blocking piece can be placed in the ball throwing device for a long time, and a cavity in the ball throwing device for holding the temporary blocking piece is often filled with water due to the problems of high-pressure water flow backflow and the like, so that an instant ball shell (made of materials which can be quickly dissolved in water such as gelatin) is adopted as a coating material of the rope knot type temporary blocking, and the ball throwing device capable of insulating water is required to be matched for better work.
