Abstract
The utility model relates to a beam -pumping unit stops sucker rod linkage for well belongs to mechanical oil extraction technical field. The device includes that upper portion promotes the short circuit and makes up linkage as an organic whole with lower part with it, and the promotion short circuit is the solid, linkage be equipped with with sucker rod external screw thread assorted counter bore formula internal thread and the external screw thread be connected with tubing coupling, it has axial pressure release hole, the pipe wall intercommunicating pore that feeds through with outer pipe wall to open on its lower extreme annular pipe wall. During closing well or braised well are scurried to the beam -pumping unit gas well gas, overpressure or emergence self -blowing, oil gas can pass through the utility model discloses lower part axial pressure release hole, flow the production tree in, carry the gathering and transferring process through the decompression of glib device, play and prevent the effect of spouting to mitigate the round trip, reached the well head pressure purpose that to bear different pressure rating.
Description
Technical field
The utility model is related to a kind of oil pumper to stop well sucker rod suspension device, especially carbon dioxide flooding rod-pumped well
Sucker rod suspension device when stewing well or gassed-out well closing well, belongs to technical field of mechanical oil extraction.
Background technology
With going deep into for oil field development, it is one of important technical of raising oil recovery factor to implement carbon dioxide flooding.
Carbon dioxide flooding be exactly using gas injection equipment, by pipe network, gas injection well carbon dioxide injection oil reservoir, it is swollen by carbon dioxide
The mechanism such as swollen, viscosity reduction increase field output, improve recovery ratio.The matter solution formulation of carbon dioxide flooding oil well base area drives a well or boils in a covered pot over a slow fire well
Working system, during oil well has channeling closing well or stewing well, oil jacket pressure is raised, and wellhead assembly has the leakage of superpressure thorn, the risk of blowout.
The wellhead assembly mainly oil-extractor polish-rod threeway wellhead assembly that current oil pumper is used, the device is using packing and polished rod in well
Mouthful place sealing gathering system, exist stress levels it is low, it is easy thorn leak defect.To prevent blowout, operation need to be implemented, rise complete in well
Portion's pipe, bar, pump, install stress levels oil and gas extraction wellhead device high.When driving a well, need operation again, under enter pipe, bar, pump recovery
Production, complex procedures, high cost.
The content of the invention
The utility model purpose is the low easy thorn leakage of the threeway wellhead assembly stress levels for overcoming above-mentioned prior art to exist, and is needed
Implement round trip, complex procedures, the defect of high cost, there is provided a kind of oil pumper stops well sucker rod suspension device.
The utility model body includes the suspension arrangement that top lifts short circuit and bottom is combined into one therewith, lifts short circuit
It is solid；Suspension arrangement is provided with the hole countersunk internal thread matched with sucker rod external screw thread and the outer spiral shell being connected with tubing coupling
Line, axial relief hole, the tube wall intercommunicating pore connected with outer tube wall are provided with the annular tube wall of its lower end.
Described body upper part is provided with the Fang Jing for screwing and dismantling sucker rod.
The hole countersunk internal thread matched with sucker rod external screw thread is designed with the lifting short circuit of described body upper part.
Uniform at least two axial relief holes on described body lower end annular tube wall.
Using the utility model, round trip can be reduced or remitted during rod-pumped well has channeling closing well or stewing well, difference can be born
The well head pressure of pressure rating, prevents conventional pumping unit threeway wellhead assembly from piercing leakage, the generation of blowout, it is to avoid petroleum resources breaks
Bad, ground environment pollution, with significant economic benefit.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is Section A-A schematic diagram in Fig. 1；
Fig. 3 is section B-B schematic diagram in Fig. 1.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model body includes that top lifts short circuit 1 and bottom is combined into one therewith
Suspension arrangement 101, lifting short circuit 1 be solid；Suspension arrangement 101 is provided with the hole countersunk matched with sucker rod external screw thread
Screw thread 102 and the external screw thread 104 being connected with tubing coupling, the axial pressure release connected with outer tube wall is provided with the annular tube wall of its lower end
Hole 103, tube wall intercommunicating pore 105.
Described body upper part is provided with the square footpath 106 for screwing and dismantling sucker rod.
The hole countersunk internal thread matched with sucker rod external screw thread is designed with the lifting short circuit 1 of described body upper part
107。
Uniform four axial relief holes 103 on described body lower end annular tube wall.
When has channeling closing well or stewing well need to be carried out to oil well, three on Well-head device of pumping well are removed using crane gear
Logical and upper flange, the internal thread 107 of lifting short circuit 1, erection ＆ lift utility model are connected with sucker rod substitute.Utility model body
Lower end external screw thread 104 is connected by screw thread with boll-weevil hanger top, underground sucker rod and utility model body lower end internal thread
102, by screwed connection, then remove the sucker rod substitute on top lifting short circuit 1, install upper flange and wellhead tree tree portion
Part is assembled into conventional wellhead assembly.By utility model, during rod-pumped well has channeling closing well or stewing well, pressure rises or occurs
Blowing, oil gas can be flowed in production tree, by oil nozzle device reduced pressure delivery by utility model bottom axial direction relief hole 103
To gathering and transferring process, blowout prevention effect is played, so as to reduce or remit round trip, reach the well head pressure that can bear different pressures grade
Purpose.
