Description

Pumpingh well lifting flow-aiding device

Technical field

This utility model relates to the device of a kind of oil field machinery oil, is a kind of pumpingh well lifting flow-aiding device.

Background technology

During heavy oil wells oil pumping, produce friction between viscous crude and sucker rod and make the descending difficulty of sucker rod so that it is can not normally pump.One of the way solving this kind of well oil pumping difficulty well-flushing, squeezes into hot water in sleeve pipe, after mixing with well liquid heats well liquid under pump so that it is fall is glutinous, increase mobility.This way is not suitable for using on the oil well of formation leakage, because during well-flushing, the head of liquid in pit shaft increases, when stressor layer above Ground, well-flushing water will not return out from well head, not reaching the purpose of well-flushing, the well-flushing water in pit shaft will drain to stratum, pollute stratum from pit shaft, reduce oil well output, even kill oil reservoir, make oil well the most fuel-displaced, produce heavy economic losses.In order to solve this problem; formation protection; oil field have developed the Flushing tubular column on protection stratum; this tubing string does not help and takes out function, although well-flushing water will not enter stratum, but well-flushing water can push down well liquid; during well-flushing, oil well pump thereon can only extract well-flushing water out; during can not taking out well liquid, well-flushing, oil well is the most fuel-displaced, affects oil well production.

Summary of the invention

The purpose of this utility model is design a kind of pumpingh well lifting flow-aiding device, can form well-flushing passage, and well-flushing water will not enter oil reservoir, and formation protection makes it not be contaminated, and has to help and take out function, improves oil well output.

nullThe purpose of this utility model is achieved in that a kind of pumpingh well lifting flow-aiding device，Including ball-and-seat、Packer，Ball-and-seat is connected with packer，Ball-and-seat only allows liquid stream to flow from bottom to top，Blocking-up liquid stream flows downward，Packer can be with the sleeve pipe fitted seal of oil well，The liquid stream in sleeve pipe is stoped to flow downwardly into stratum，Also include jet-sub、Top connection、Anemostat、Nozzle、Tap，Lateral import is had on tap、UNICOM's chamber、Vertical groove，UNICOM's chamber pierces from the middle part of tap upper end，Lateral import is squeezed into from the side of tap and chamber UNICOM of UNICOM，Vertical groove is in the side within tap，The described bottom of vertical groove communicates with the bottom of tap，The upper surface of tap is led on the top of vertical groove，The top of nozzle is connected to the bottom of jet-sub，Anemostat is connected to the top of jet-sub，Hybrid chamber is had between anemostat and nozzle in jet-sub，There is linked hole at the middle part of jet-sub，Described linked hole is between anemostat and nozzle，Described linked hole communicates with described hybrid chamber，Top connection is sleeved on outside jet-sub，The bottom of top connection is connected with the top of tap，The bottom of top connection forms feed liquor annular chamber after being connected with the top of tap in top connection，Described feed liquor annular chamber is communicated with hybrid chamber by described linked hole，Described feed liquor annular chamber is on tap，Described vertical groove is made to communicate with described feed liquor annular chamber，The bottom of tap is connected with the top of ball-and-seat.

The beneficial effects of the utility model are: after well-flushing water squeezes into well-flushing water in sleeve pipe, at ball-and-seat, under the effect of packer, well-flushing water cannot flow into stratum, when reaching the anti-stick purpose of well-flushing, stratum can also be protected the most contaminated, well-flushing water can only enter from lateral import and make to be formed hybrid chamber low-pressure area through nozzle ejection, attract the well liquid come from ground laminar flow, well liquid sprays from anemostat after mixing with well-flushing water in hybrid chamber low-pressure area, therefore, can normally pump during this utility model well-flushing, and owing to defining low-pressure area, oil well output can also be added, there is significant economic benefit.
