Abstract

The invention provides a high-stability injector for oilfield downhole, and relates to the technical field of oilfield downhole equipment. The distributor for oil wells based on high stability includes: a main fixing structure, which realizes the combination and fixing of all structures; a control structure, which realizes the control of the distributor on the distribution flow Control; fastening structure, said fastening structure realizes the increased tightness of the dispenser body in operation. By starting the driving motor installed on one side of the fixed cylinder, the motor drives the fixed pinion of the output shaft to rotate, the rotation of the pinion drives the gear ring meshing with it to rotate, and the connecting rod fixed evenly at the bottom drives the inner threaded ring in the fixed Rotation inside the cylinder drives the air pipe to move upwards, opening up all the multi-stage through holes evenly distributed in the longitudinal direction inside the dispensing head, increasing the output flow of steam, and the air pipe can be blocked in turn by reversing the gear ring. Through-hole, it is worth vigorously promoting.

Description

technical field [0001] The invention relates to the technical field of oilfield downhole equipment, in particular to a high-stability oilfield downhole distributor. Background technique [0002] In oil field production, thermal recovery wells used for heavy oil recovery need to inject steam downhole to reduce the viscosity of crude oil, so the injector can be used to inject steam into the crude oil to reduce the viscosity. The injector is commonly used in the tertiary oil recovery process of the oil field It is a downhole tool whose function is to adjust the polymer injection rate of each reservoir to better achieve the purpose of production stimulation. [0003] Referring to the description of Chinese patent document CN103603641A, when distributing steam, the general dispenser is often unable to control the steam flow, which makes it difficult to control the viscosity of crude oil. If the flow is too much or too fast, it will If the viscosity is too low and the flow rate i...
