Abstract
The utility model relates to an electric pump sand-settling apparatus, which is used for an electric pump oil-production well. The electric pump sand-settling apparatus is composed of an upper joint, an outer pipe, a sand accumulating pipe and a bulkhead, wherein the lower part of the upper joint is connected with the upper part of the outer pipe and the sand accumulating pipe is hung on the upper part in the outer pipe. The bulkhead is connected to the lower part of the sand accumulating pipe and a communicating hole A is arranged on the sand accumulating pipe. The lower part of the outer pipe is connected with a check valve and a circulating flow passage is formed by the outer pipe and the sand accumulating pipe. Well liquid passes through the circulating flow passage and flows into an oil pipe on the upper part of the electric pump sand-settling apparatus through the communicating hole A of the sand accumulating pipe. When the electric pump oil well is stopped pumping, sand in the well liquid is subsided after separation and is fallen in the sand accumulating pipe. The sand is blocked in the sand accumulating pipe by the bulkhead, and thus the sand can not be fallen on the electric pump. Thus the electric pump can not be clamped by the sand, a flow passage can not be plugged by the sand, the stop production of the electric pump oil well can be reduced and the production time of the electric pump oil well can be prolonged.
Description
One, technical field
The utility model is a cover mechanical device of oil field oil recovery industrial technology, the electric pump sand-settling device that particularly a kind of electric pump oil-producing well is used.Belong to engineering goods.
Two, background technology
Present electric pump pipe column is blank tubing more than electric pump, and after stop pumping for some reason, the sand in the well liquid separates the back and sinks, drop on the electric pump, the problem of sand card electric pump and sand plugging fluid circulation road occurs, the electric pump oil well can not be driven a well, damage electric pump, operation inspection pump causes heavy economic losses again.
Three, summary of the invention
The purpose of this utility model provides a kind of electric pump sand-settling device, is connected in electric pump top, after stop pumping for some reason; sand in the well liquid separates the back and sinks, and can not drop on the electric pump, plays the effect of protection electric pump; avoid sand card electric pump and sand plug plug fluid course, can drive a well again smoothly after making stop pumping for some reason.
The utility model is achieved in that by top connection, outer tube, sand deposition tube, plug to be formed, and the top connection bottom connects with outer tube top, and sand deposition tube is suspended on outer tube top and is in the outer tube, and plug is connected in the bottom of sand deposition tube, and linked hole A is arranged on the sand deposition tube.The outer tube bottom connects with ball-and-seat.
The utility model is installed on electric pump top, outer tube and sand deposition tube form circulation channel, well liquid is through this circulation channel, flow into the top oil pipe of electric pump sand-settling device again through the linked hole A of sand deposition tube, when oil well for some reason after the stop pumping, the sand in the well liquid separates the back and sinks, and drops in the sand deposition tube, be blocked in the sand deposition tube by plug, so sand can not drop on the electric pump again.
The beneficial effects of the utility model are: the sand that sinks after the stop pumping for some reason can be collected in the sand deposition tube, sand can not drop on the electric pump, thereby avoids sand card electric pump and sand plug plug fluid course, can reduce the electric pump oil well and stop production, and prolongs the electric pump oil well production time.
Four, description of drawings
Accompanying drawing is the structure half sectional view of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is described further below:
Be made up of top connection 1, outer tube 2, sand deposition tube 3, plug 4, top connection 1 bottom connects with outer tube 2 tops, and sand deposition tube 3 is suspended on outer tube 2 tops and is in the outer tube 2, and plug 4 is connected in the bottom of sand deposition tube 3, and linked hole A is arranged on the sand deposition tube 3.Outer tube 2 bottoms connect with ball-and-seat 5.
