Abstract

The invention relates to a bubble breaking type mixing power transmission submersible pump impeller. The bubble breaking type mixing power transmission submersible pump impeller comprises a front cover plate, a shaft sleeve, a rear cover plate and a blade; the blade is a segmented blade, and a bubble breaking jet fracture opening breaks in the unfolding direction of the segmented blade and forms abubble breaking jet seam; a front blade is arranged in front of the bubble breaking jet seam, a rear blade is arranged behind the bubble breaking jet seam, and the shape of the bubble breaking jet seam is matched with the gap between the tail edge of the front blade and the front edge of the rear blade; the rear cover plate is provided with a plurality of gas breaking jet hole sets, each gas breaking jet hole set is composed of a plurality of round holes, the gas breaking jet hole set located at the front blade is a front jet hole set, and the gas breaking jet hole set located at the rear blade is a rear jet hole set. The bubble breaking type mixing power transmission submersible pump impeller can avoid gas locking under the condition that the gas content reaches 70% and normally jack gas-liquid mixed liquid.

Description

[0001] Technical field: [0002] The invention relates to a centrifugal impeller used for conveying a two-phase flow product liquid with high gas content in an oil extraction system of an electric submersible pump, in particular to an impeller of a bubble crushing hybrid transmission submersible pump. [0003] Background technique: [0004] With the development of the economy, people's demand for oil is increasing day by day, and the oil industry plays an increasingly important role in the entire national economy. As oil exploitation enters the middle and late stage, the formation energy is gradually consumed, and the extraction method is changed from the initial use of formation energy to lift crude oil to the ground to artificial lift. Artificial lift has become the main way of oilfield exploitation. Commonly used artificial lift methods are divided into: rod pump oil production and rodless pump oil production. Rod pump oil production is divided into beam pumping unit oil p...
