Abstract
The utility model relates to a vibration oil production device preventing well clean-up pollution, comprising an upper joint, a central tube, a self-sealing bowl, a sand leaking hole, a baffle ring, a check valve joint, a valve cover, a valve ball, a ball seat, a ball seat joint, a vibrating reed joint, a vibrating reed central tube, a vibrating reed, a compact joint and a liquid inlet pipe, wherein the self-sealing bowl is arranged on the central tube provided with the upper joint, and internally provided with a U-shaped cavity; the self-sealing bowl is internally provided with the sand leaking hole communicated with the central tube; the baffle ring is arranged below the self-sealing bowl; the check valve composed of the check valve joint, the valve cover, the valve ball and the ball seat is arranged at one end of the central tube; the lower part of the check valve is connected with the ball seat joint and the vibrating reed joint; the vibrating reed joint is connected with the vibrating reed central tube; the vibrating reed is arranged on the vibrating reed central tube; and the liquid inlet pipe is connected with one end of the central tube through the compact joint. The device has the advantages of preventing the well cleaning liquid from entering the oil layer to pollute the oil layer, being capable of generating vibration waves and negative pressure chimney effect to eliminate the oil layer near-well zone blocking, improving the hot washing efficiency, and improving the oil well yield and the like.
Description
Technical field
The utility model relates to a kind of extracting device of oil, a kind ofly specifically prevents that flushing fluid from entering oil reservoir and causing oil layer pollution, produces vibration wave and negative pressure swabbing action simultaneously and removes the anti-well-flushing that stops up the oil reservoir near wellbore zone and pollute the vibrating oil production device.
Technical background
The oil field was for solving the method that the oil well paraffinication problem adopts the high-temp liquid well-flushing usually in the past, and there are many drawbacks in above-mentioned pumping and washing process, is in particular in, this method unavoidably makes flushing fluid enter oil reservoir and causes oil layer pollution in wax removal; In addition, oil well drilling mud, colloid, asphalitine, mechanical admixture, well killing fluid etc. in process of production forms pollution to oil reservoir and stops up, and causes oil well output to descend, and influences the performance of oil well productivity.
Summary of the invention
The purpose of this utility model is to solve problems such as oil well flushing fluid polluted reservoir and near wellbore zone obstruction for the oil field a kind of anti-well-flushing pollution vibrating oil production device that heat is washed efficient, improved oil well output that improves is provided.
The purpose of this utility model is achieved through the following technical solutions: this extracting device of oil comprises by top connection, central tube, from the sealing bowl, leak sand hole, baffle ring, the one way valve joint, valve bonnet, valve ball, ball seat, ball joint, the vibrating reed joint, the vibrating reed central tube, vibrating reed, pressed joint, feed tube, describedly be arranged on the central tube that has top connection from the sealing bowl, in the sealing bowl, be provided with the U die cavity, in the sealing bowl, have the leakage sand hole that is communicated with central tube, baffle ring is arranged on below the sealing bowl, by the one way valve joint, valve bonnet, valve ball, the one way valve that ball seat constitutes is arranged on an end of central tube, the one way valve bottom is connected with ball joint and vibrating reed joint, be connected with the vibrating reed central tube on the vibrating reed joint, vibrating reed is arranged on the vibrating reed central tube, and feed tube is connected an end of central tube by pressed joint.
The utility model reasonable in design, easy to process, complete function, easy operating, can extensively be useful in the oil well and the oil reservoir that need anti-flushing well exists in the oil well that stops up, this device can prevent that not only the flushing fluid polluted reservoir from causing oil well output to descend, the minimizing flushing fluid returns row influences produce oil, improve heat and wash efficient, can remove the pollution and the obstruction of adjacent to oil well area again, improve oil well output.

The specific embodiment
Shown in accompanying drawing 1: this extracting device of oil comprises by top connection 1, central tube 2, from sealing bowl 3, leaks sand hole 4, baffle ring 5, one way valve joint 6, valve bonnet 7, valve ball 8, ball seat 9, ball joint 10, vibrating reed joint 11, vibrating reed central tube 12, vibrating reed 13, pressed joint 14, feed tube 15, describedly be arranged on the central tube 2 that has top connection 1 from sealing bowl 3, in sealing bowl 3, be provided with U die cavity 16, by the bloated envelope of oil sets annular space pump intake pressure, stop flushing fluid to enter glue lower part of bowl oil sets annular space; In sealing bowl 3, have the leakage sand hole 4 that is communicated with central tube 2, baffle ring 5 is arranged on below sealing bowl 3, the one way valve that is made of one way valve joint 6, valve bonnet 7, valve ball 8, ball seat 9 is arranged on an end of central tube 2, the one way valve bottom is connected with ball joint 10 and vibrating reed joint 11, be connected with vibrating reed central tube 12 on the vibrating reed joint 11, vibrating reed 13 is arranged on the vibrating reed central tube 12, and feed tube 15 is connected an end of central tube 12 by pressed joint 14.
Using method and operating principle are: top connection 1 is connect under the oil well pump floral tube, go into the well with the oil well operation.By the bloated envelope of oil sets annular space pump intake pressure, stop flushing fluid to enter glue lower part of bowl oil sets annular space from sealing bowl 3; One way valve stops flushing fluid to enter oil reservoir through central tube; Flushing fluid enters oil well pump through floral tube during well-flushing, prevents that flushing fluid from entering oil reservoir.Vibrating reed 13 produces vibration wave by oil pipe elastic telescopic energy, produces negative pressure suction and percussion from 3 pairs of oil reservoirs of sealing bowl, makes the pollution of oil reservoir near wellbore zone and stops up loosening and come off, and discharges with produced liquid in oil well.
