Abstract

The invention relates to a throwing and fishing injection dispenser, in particular to a differential pressure flow meter-type smart adjustable throwing and fishing injection dispenser, and aims to solve the problems that the eccentric injection dispenser used by the current oilfield polymer injection well cannot continuously adjust injection amount, cannot achieve precise injection and has relatively poor sealing performance. The differential pressure flow meter-type smart adjustable throwing and fishing injection dispenser comprises an upper connector body, an upper cable body, a pin body, a pin bridging component, a pin locking nut, a motor housing, a bearing housing, a connecting body, an upper casing body, a lower connector body, a central tube, a bearing set ejecting wire, a rigid coupling, an anti-rotating body, a middle cable connector assembly, an upper cable connector assembly, a shaft connecting rod, a vehicle-type seal installing frame, a bearing assembly, a vehicle-type seal, a pressure sensor, a motor, a plugger and a cable connector body. The differential pressure flow meter-type smart adjustable throwing and fishing injection dispenser is applied to oilfields.

Description

Technical field [0001] The invention relates to an injection and fishing dispenser, in particular to a differential pressure flow meter type intelligent adjustable casting and fishing dispenser. Background technique [0002] Energy is the lifeblood of the country’s economic development and the original driving force for the country’s economic development. Petroleum, as the core energy component, has its strategic significance and economic value self-evident. At present, my country's oilfield exploration and development have gone through half a century of development. The main production areas of national oil-Daqing, Shengli and other oilfields have gradually entered the stage of high water cut, and some water cuts have reached more than 90%. Therefore, the secondary oil recovery technology centered on water injection and oil recovery has gradually come to an end, and its impact on oil recovery has gradually weakened. In order to ensure the national strategic material, energy res...
