Abstract
A wellhead protection device for a paraffin removal oil well by adopting hydrothermal circulation is connected with a hose line connected between a liquid production gate and a back pressure gate of the oil well. And the high-pressure metal hose is connected with the steel pipe coupling and the three-way steel pipe, so that the height compensation of the wellhead is realized. The wellhead compensator for the hydrothermal liquid paraffin removal oil well is characterized in that: the steel pipe coupling is connected with one pipe orifice of the three-way steel pipe, and one end of the high-pressure metal hose is connected with the other pipe orifice of the three-way steel pipe. The other end of the high-pressure metal hose is connected with a hose connector. The hose connector is welded on the flange. The effect is that the hydrothermal paraffin removal oil well wellhead compensator can realize the connection between the liquid production gate and the back pressure gate; because the high-pressure metal hose is arranged in the connecting pipe fitting, the defect of fracture accidents of the connecting pipeline caused by the rise of a wellhead during hot liquid paraffin removal construction can be overcome.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, is a kind of tree-protector that adopts hydrothermal solution circulation wax removal oil well, is a kind of soft pipeline that connects between oil well liquid-producing gate and the back pressure gate that connects specifically.
Background technology
At high content of wax area well recovery, often need safeguard oil well, remove oil well paraffinication.The method of removing wax deposition is a lot, as adding the paraffin removing with chemical method of paraffin remover, thinner, wax-proofing agent in toward oil well; In toward oil well, inject hydrothermal solution, improve the thermal recovery technology of oil temperature.In carrying out hydrothermal solution wax removal process, because the long sleeve pipe expanded by heating of the thousands of rice in down-hole, the cementing quality of adding some well is poor, washes in the process in heat, and well mouth of oil well will raise.Well head raises and causes producing height change between the connected back pressure gate of production fluid gate, the flow process pipeline distortion of connection.When distortional stress meets with stresses above the flow process pipeline, phenomenon of rupture will take place in the pipeline junction, cause the generation of hydrothermal solution wax removal construction accident.For production brings utmost point adverse influence, there is serious potential safety hazard.
The utility model content
The purpose of this utility model is: a kind of hydrothermal solution wax removal well mouth of oil well expansion loop is provided, realizes being connected between production fluid gate and the back pressure gate, cause the deficiency of connecting line fracture accident when overcoming the construction of hydrothermal solution wax removal owing to the well head rising.
The technical solution adopted in the utility model is: utilize the high-pressure metal flexible pipe to be connected with the threeway steel pipe with the steel pipe box cupling, be made into when the well head rising takes place and bear the distortion connection by the high-pressure metal flexible pipe, realize the effect of altimetric compensation.
Hydrothermal solution wax removal well mouth of oil well expansion loop concrete structure is: the steel pipe box cupling connects a mouth of pipe of threeway steel pipe, and high-pressure metal flexible pipe one end connects another mouth of pipe of threeway steel pipe.The other end of high-pressure metal flexible pipe connects hose coupling.Hose coupling is welded on the flange.
Be connected between threeway steel pipe and the high-pressure metal flexible pipe and can adopt high-voltage quick joint.
The nominal diameter of threeway steel pipe, high-pressure metal flexible pipe and flange is the 45-80 millimeter.
The high-pressure metal flexible pipe by sale, is generally selected the high-pressure metal flexible pipe of withstand voltage 10MPa in market.
The beneficial effects of the utility model: adopt hydrothermal solution wax removal well mouth of oil well expansion loop can realize being connected between production fluid gate and the back pressure gate; Owing to the high-pressure metal flexible pipe is arranged in the connecting tube, belong to and flexibly connect, well head raises and causes the deficiency of connecting line fracture accident in the time of overcoming the construction of hydrothermal solution wax removal.
Through oil recovery factory's probationary certificate, hydrothermal solution wax removal well mouth of oil well expansion loop security performance is reliable, do not influence other facility operation of well head after simple installation, the installation, not influencing miscellaneous equipment normally uses, well after the installation has thoroughly been eliminated the accident of well head connecting tube generation fracture when heat is washed, save 33.8 ten thousand yuan of accident treatment costs, be subjected to user's favorable comment.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model structural profile schematic diagram.
Among the figure, 1. steel pipe box cupling, 2. threeway steel pipe, 3. high-voltage quick joint, 4. high-pressure metal flexible pipe, 5. hose coupling, 6. flange.
