Description

Technical Field

[0001] The utility model relates to the technical field of oil field production equipment, in particular to a ball throwing device for oil field fracturing. Background Art

[0002] At present, in the acid fracturing operations in oil and gas fields, stratified fracturing generally includes four forms: packer stratified fracturing, plugging ball selective fracturing, flow limiting valve stratified fracturing, and wax ball selective fracturing. The results of acidifying stratified fracturing operations in oil and gas fields for many years show that traditional packer stratified fracturing, flow limiting valve stratified fracturing, and wax ball selective fracturing operations are difficult to achieve the expected stratified fracturing operation effect due to outdated technology, high operating difficulty, and high fracturing cost, especially in deep well acid fracturing operations. On the contrary, the plugging ball selective fracturing process has gradually replaced other traditional stratified fracturing modes due to its significant stratified fracturing effect, convenient ball plugging operation, and economical operating cost.

[0003] According to the search, Chinese patent literature, announcement number: CN217151912U, discloses a ball throwing device for oil field fracturing, which adopts the working mode of normal pressure counting and high-pressure ball throwing, wherein the translation seal body adopts a translation conveying method to quantitatively transport the fracturing balls in the normal pressure area to the high-pressure area and realize the release of the fracturing balls. It is suitable for various sizes of steel balls, low-density degradable balls and soluble temporary plugging ball fracturing construction. A set of equipment meets various construction requirements and withstands high pressure (can reach 105Mpa or above). However, since the fracturing ball is in a high-speed ejection state during the throwing process, it is easy to generate internal heat from friction with the inner wall due to high-speed movement, thereby increasing the temperature of the entire device and affecting the personnel's picking work, so an auxiliary structure is needed to perform cooling treatment in time to avoid adverse effects caused by high temperature.
