Abstract
The utility model relates to an electric sand sinking device for an electric pump oil well, composed of a tubing collar, a retaining joint, a sand sinking tube, a plugging joint and an oil pipe. The upper part of the sand sinking pipe is provided with a communicating groove, the lower part thereof is plugged by the plugging joint and is connected to the retaining joint and is suspended in the tube by the retaining joint to form a liquid flow channel between the tube and the sand sinking tube. When the electric pump oil well stops pumping, the separated sands in the tube on the pump fall into the sand sinking tube instead of the electric pump, thus to prevent the electric pump from being plugged by sands and prevent the liquid flow channel from being blocked by sands, therefore the electric pump oil well stops production for less times and the production time of the electric pump oil is prolonged.
Description
One, technical field
Electric pump sand setting device belongs to a cover mechanical device of oil field oil recovery industrial technology.
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, and drops on the electric pump, the problem of sand card electric pump and sand plug plug fluid course occurs, and oil well can not drive a well, and causes heavy economic losses.
Three, summary of the invention
The purpose of this utility model provides a cover electric pump sand setting device; this covering device is connected in electric pump top; after stop pumping for some reason; sand in the well liquid separates the back and sinks; drop in this device, can not drop on the electric pump, play 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 it is made up of tubing coupling, retaining joint, sand sediment pipe, stifled joint, oil pipe.Sand sediment pipe top has UNICOM's groove, to keep off joint, sand sediment pipe, block up and put into oil pipe after joint is connected into one, because the top external diameter of retaining joint is greater than pipe aperture, therefore sand sediment pipe is suspended in the oil pipe, make oil pipe and sand sediment pipe form circulation channel, well liquid is through this circulation channel, go into the top oil pipe of electric pump sand setting device again through UNICOM's concentrated flow of sand sediment pipe, when oil well for some reason after the stop pumping, sand in the well liquid separates the back and sinks, drop in the sand sediment pipe, the joint that is blocked is blocked in the sand sediment pipe, so sand can not drop on the electric pump again.
The utility model is installed on electric pump top, the sand that sinks after the stop pumping for some reason can be collected in the sand sediment pipe, and 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.
Among the figure: the 1st, tubing coupling, 2 retaining joints, 3 sand sediment pipes, 4 stifled joints, the 5th, oil pipe.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is described further below:
This device is installed on the electric pump upper end.Sand sediment pipe (3) is connected under the retaining joint (2), and is in the oil pipe (5), stifled joint (4) is connected under the sand sediment pipe (3), and retaining joint (2) is suspended on oil pipe (5) upper end.Retaining joint (2) top external diameter is greater than the internal diameter of oil pipe (5), therefore, sand sediment pipe (3) and stifled joint (4) are suspended in the oil pipe (5), make oil pipe (5) and sand sediment pipe (3) form circulation channel B, the liquid circulation channel B that flows through flows through and enters oil pipe on the pump behind the groove A of UNICOM on sand sediment pipe (3) top, and oil pipe is connected in the tubing coupling (1) on the pump.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 sediment pipe (3), and the joint that is blocked (4) is blocked in the sand sediment pipe (3), so sand can not drop on the electricity again.
Claims (2)
1, the electric pump sand setting device used of a kind of electric pump oil well, form by tubing coupling (1), retaining joint (2), sand sediment pipe (3), stifled joint (4), oil pipe (5), it is characterized in that sand sediment pipe (3) is connected under the retaining joint (2), and be in the oil pipe (5), stifled joint (4) is connected under the sand sediment pipe (3), and retaining joint (2) is suspended on oil pipe (5) upper end.
2, electric pump sand setting device according to claim 1 is characterized in that sand sediment pipe (3) top has the groove A of UNICOM.
