Abstract
The utility model discloses an oil well annular pipe gas vertical drain device. An oil pipe screw thread is arranged inside a suspending device and an up-and-down communicated hole whose upper end is provided with an annular pipe with gas drain pipe inside is disposed between the oil pipe screw thread and its outer surface. A valve ball is arranged under the gas drain pipe. The oil pipe is connected under the suspending device whose outer conical face is provided on the annular pipe to separate the oil pipe and the annular pipe into two air-tight pressure spaces when the oil well is in use. The outlet opening of the annular pipe is closed while pumping the oil thereby burglar can not access the gas through the annular pipe. The crude oil flow upward towards the oil pipe line inside the suspending device and won't enter the annular pipe through the communicated hole on the suspending device under the action of the valve ball. When the natural gas separated from the annular pipe accumulates and the pressure is above the oil pipe line pressure, the valve ball opens and the natural gas inside the annular pipe directly enters the oil pipe line, thereby recycling the natural gas, preventing burglar and the negative influence on the pumping effects caused by the gas drain block after the pressure increases inside the annular pipe.
Description
One, technical field
The utility model is the device of using on the oil well, is the in line device of a kind of well casing gas, belongs to engineering goods.
Two, background technology
In oil field pumping well, all to isolate natural gas in the sleeve pipe, natural gas easy stolen molecule in sleeve pipe connects away with simple and easy pipeline, causes the wasting of resources, also occurs security incident easily.If sleeve pipe is shut, the natural gas in the sleeve pipe is not drained, and can influence the pump efficiency of oil well pump, even can cause the oil well pump gas lock and can't normally pump, and makes oil well not fuel-displaced.
Three, summary of the invention
The purpose of this utility model is the in line device of a kind of well casing gas of design, and it can be drained into the sleeve pipe gas of pumpingh well on the flow line, avoids natural gas stolen, avoids the gas influence oil well pump pump efficiency in the sleeve pipe.
The purpose of this utility model is achieved in that by stack, valve ball, sleeve, hanger to be formed, there is tubing round thread hanger inside, the hole that UNICOM about in the of is arranged between the tubing round thread of hanger and the external surface, the axis in hole is parallel with the tubing round thread axis, upper end installing sleeve in the hole, stack is installed in the sleeve, is placed valve ball under the stack.Mounting spring between valve ball and the stack.Seal groove and copper ring groove are arranged on the hanger outer cone surface.
The beneficial effects of the utility model are: when the utility model is used for oil-pumping well sheath collection natural gas, can directly be drained into the sleeve pipe gas of pumpingh well on the flow line, make natural gas obtain recycling, can be not stolen, avoid the gas influence oil well pump pump efficiency in the sleeve pipe.
Four, description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Among the figure: the 1st, stack, the 2nd, spring, the 3rd, valve ball, the 4th, sleeve, the 5th, hanger.Be that the utility model is made up of stack 1, spring 2, valve ball 3, sleeve 4, hanger 5, there is tubing round thread hanger 5 inside, the hole that UNICOM about in the of is arranged between tubing round thread and the external surface, the axis in hole is parallel with the tubing round thread axis, upper end installing sleeve 4 in the hole, stack 1 is installed in the sleeve 4, is placed valve ball 3 under the stack 1.Mounting spring between valve ball and the stack.Seal groove and copper ring groove are arranged on hanger 5 outer cone surfaces.
During the oil well operation, oil pipe is connected under the hanger 5, the male cone (strobilus masculinus) of hanger 5 is located on the sleeve pipe big four and makes oil pipe, bobbin seal becomes two pressure spaces, during oil pumping, shut the sleeve pipe outlet, thief can't connect gas from sleeve pipe, and crude oil upwards flow to flow line in the hanger 5, under valve ball 3 effects, can not flow in the sleeve pipe by the linked hole on hanger, isolated natural gas increases in sleeve pipe, and when pressure was higher than flow line pressure, valve ball 3 was opened, natural gas straight in the sleeve pipe connects and is drained in the flow line, thereby make natural gas obtain recycling, can be not stolen, can not discharge after avoiding natural gas in the sleeve pipe to raise influences the oil well pump pump efficiency.
Claims (3)
1, the in line device of a kind of well casing gas, it is characterized in that: form by stack (1), valve ball (3), sleeve (4), hanger (5), there is tubing round thread hanger (5) inside, the hole that UNICOM about in the of is arranged between the tubing round thread of hanger (5) and the external surface, the axis in hole is parallel with the tubing round thread axis, upper end installing sleeve (4) in the hole is installed stack (1) in the sleeve (4), place valve ball (3) under the stack (1).
2, the in line device of well casing gas according to claim 1 is characterized in that: mounting spring (2) between valve ball (3) and the stack (1).
