Description

Anomalous character plastic cement injects packing_seal wellhead assembly and method
Technical field
The invention belongs to oil pumping well head sealing device, relate to a kind of Anomalous character type glue specifically and inject packing well-sealing device and method.
Background technology
During oil producing operation, wellhead sealing and eccentric wear directly affect the operating efficiency of oil recovery.The most function singleness of existing well mouth sealing device, packing unreasonable structure, causes packing utilization rate low, and operation process is complicated, and poor stability, the packing replacing cycle is short, and extend maintenance time, production efficiency is low.And traditional well mouth sealing device pellet function is not good, cause waste and cleaning difficulty.
Summary of the invention
In order to solve the problem, the present invention aims to provide a kind of reasonable in design, safety, energy-conserving and environment-protective, operating efficiency is high, packing utilization rate is high, diverse in function, the convenient Anomalous character type glue produced inject packing well-sealing device and method.
Anomalous character plastic cement of the present invention injects packing_seal wellhead assembly, be made up of one section of packing box, two sections of packing boxs, shut-in valve, eccentric mid-game and spray-proof balls adjusted, packing pressure cap is had on the top of one section of packing box, tube wall is established the first plastic cement inlet, the lower end of one section of packing box is connected with the upper end of two sections of packing boxs; The lower end of two sections of packing boxs is connected with sleeve pipe by regulating pressure cap, and the tube wall of sleeve pipe is provided with the second plastic cement inlet, and the lower end of sleeve pipe is connected with shut-in valve; The tube wall of the junction of one section of packing box and two sections of packing boxs has drain tap, and drain tap is connected with receiving flask by short circuit.
Anomalous character plastic cement of the present invention injects the method for packing_seal well head, that glue injection machine is connected with glue inlet, propelling piston pressurizes, latex in glue injection machine enters in one section of packing box or two sections of packing boxs by each glue inlet respectively, and under pressure state, coagulation forming is one section of plasticity packing and two sections of plasticity packings respectively.
Anomalous character plastic cement of the present invention injects packing_seal wellhead assembly and method, packing adopts Dynamic injection, packing box is met and does not stop well filling pellet, packing utilization rate reaches 100%, reach do not stop well filling pellet, facilitate device to safeguard, saved manpower and the time of changing packing, energy consumption is low, safety and environmental protection, has the beneficial effect of energy efficiency and Reduction of Students' Study Load.
Accompanying drawing explanation
Fig. 1 is the structural representation that Anomalous character plastic cement injects packing_seal wellhead assembly.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
Anomalous character plastic cement of the present invention injects packing_seal wellhead assembly, is to be made up of one section of packing box, 1, two sections of packing boxs 2, shut-in valve 3, eccentric mid-game 4 and the spray-proof ball 5 adjusted.There is packing pressure cap 6 on the top of one section of packing box 1, tube wall is established the lower end of the first plastic cement inlet 7, one section of packing box 1 be connected with the upper end of two sections of packing boxs 2; The lower end of two sections of packing boxs 2 is connected with sleeve pipe 9 by regulating pressure cap 8, and the tube wall of sleeve pipe 9 is provided with the second plastic cement inlet 10, and the lower end of sleeve pipe 9 is connected with shut-in valve 3; The tube wall of the junction of one section of packing box 1 and two sections of packing boxs 2 has drain tap 11, and drain tap 11 is connected with receiving flask 13 by short circuit 12.
Anomalous character plastic cement of the present invention injects the method for packing_seal well head, that glue injection machine 14 is connected with the first plastic cement inlet 7 or the second plastic cement inlet 10, propelling piston 15 pressurizes, latex in glue injection machine 14 enters in one section of packing box 1 or two sections of packing boxs 2 by the first plastic cement inlet 7 or the second plastic cement inlet 10 respectively, and under pressure state, coagulation forming is one section of plasticity packing 16 and two sections of plasticity packings 17 respectively.
During use, first glue injection machine is aimed at the first plastic cement inlet 7 and the second plastic cement inlet 10, one section of packing box 1 and two sections of packing boxs 2 are filled, said process directly can be annotated when not stopping well pellet.When sucker rod is twitched, the attachment on sucker rod is through the scraping of one section of plasticity packing 16, and its excess oil and attachment flow in receiving flask 13 through short circuit.When oil well does not use, available plug is by drain tap shutoff.
Packing adopts Dynamic injection, does not stop well filling pellet, facilitates device to safeguard, has saved manpower and the time of changing packing.
