A full range of large-capacity automatic ball-loading digitally controlled segmental fracturing ball dispensers

Abstract

The invention discloses a full-series large-capacity automatic ball installing and digital control staged fracturing ball injector. The full-series large-capacity automatic ball installing and digital control staged fracturing ball injector comprises a ball injector body, an alternating-current digital servo motor, a ball room, a ball injector driving end and a ball injector discharging end. A chain is driven to rotate by the alternating-current digital servo motor to drive the ball room on the chain to rotate, and ordered or unordered ball injection is achieved through a programmable logic controller and a position sensor. The full-series large-capacity automatic ball installing and digital control staged fracturing ball injector can be widely applied to oil-and-gas well acid fracturing operation and can be particularly and widely applied to staged and layered fracturing operation of unconventional gas horizontal well. The number of installed balls is large, and 33 balls of any stage difference can be installed from any positions in the ball room in an ordered or unordered mode automatically or manually and can be put from any positions in an ordered or unordered mode automatically or manually. The inner wall of the ball injector is processed through corrosion prevention and acid and alkali prevention technologies, chrome is plated with the surfaces of all parts making contact with fracturing fluid, V-type sealing and O-type sealing are adopted in sealing portions, and sealing under high-pressure operation is greatly guaranteed.

Description

technical field [0001] The invention relates to the field of conventional and unconventional oil and gas horizontal wells and vertical wells segmented and layered acidizing fracturing operations in oil and gas fields, in particular to a full series of large-capacity automatic ball loading digital control segmented fracturing ball throwers. Background technique [0002] With the development of science and technology, the demand for energy continues to increase, while the amount of conventional energy minerals is decreasing, and the amount of mining can no longer meet the needs of social development. As an important supplement to conventional energy, shale gas unconventional energy has become a new type of energy. Under the guidance of mature shale gas mining technologies abroad, China has the largest shale gas reserves in the world. At the same time, the shale gas unconventional energy industry has already started. With the strengthening of policy support, there will be large...
