Abstract
The utility model relates to a pumping well wellhead device. A controlling body is arranged in a hanging body which is connected downward with big thread of the upper portion of a diverting connector, small thread of the upper portion of a diverting connector is connected with the lower portion of a dividing pressure pipe which is arranged in the hanging body, the combination between the upper portion of the dividing pressure pipe has the sealing effect, the lower portion of the dividing pressure pipe and the hanging body form a ring space, small thread of the lower portion of the diverting connector is connected with a pump cylinder, big thread of the lower portion of the diverting connector is connected with an oil tube, side of the diverting connector is provided with a one-way valve, the upper portion of a plunger piston is connected with a polish rod and the plunger piston, the polish rod are arranged in a pump cylinder and the combination between the plunger piston and the pump cylinder has the sealing effect. When the utility model is used for pumping oil, the pressure of the lower portion of the plunger piston is the borehole pressure, and the pressure of the upper portion of the plunger piston is the tube pressure which is often the atmospheric pressure, therefore a polish rod sealer is not arranged on the top of the pumping well wellhead device, which leaves the operation of fastening polish rod sealer out, thereby preventing the thieves from stealing oil from the polish rod sealer and preventing environmental pollution.
Description
One, technical field
The utility model belongs to the mouth of pumped oil well device that oil field machinery oil is used.
Two, background technology
Present mouth of pumped oil well device need be installed polished rod sealer, the bearing capacity of polished rod sealer is limited, when thief closes dead delivery valve behind the door, oil pumper is still in oil pumping, and the oil pipe internal pressure raises, the polished rod sealer pressure-bearing increases, be easy to surpass the operating pressure of polished rod sealer, make the leakage of oil of pumpingh well well head, cause the crude oil loss on the one hand, cause environment dirt seven on the other hand, bring very big economic loss to the oil field.The patent No. is 00256059.3 guard against theft oil wellhead assembly, can play the effect of certain guard against theft oil, but it needs also the light sealer is installed, need the continuous fastening polished rod sealer of oil recovery worker could guarantee that well head is oil-proof, oil recovery workman maintenance workload is big, for outlying well management inconvenience.
Three, summary of the invention
The purpose of this utility model is a kind of mouth of pumped oil well device of design, makes its mouth of pumped oil well device not need to install polished rod sealer, removes the work of the fastening polished rod sealer of oil recovery workman, and the molecule that avoids theft also can prevent the pollution of the environment from the polished rod sealer stolen.
The purpose of this utility model is achieved in that the control volume bottom connects with sleeve pipe, suspension body is installed in control volume, suspension body lower link tap top major thread, tap top minor thread with connect every the pressure pipe bottom, in pressure pipe is in suspension body, cooperate with suspension body every pressure pipe top and to seal, between pressure pipe bottom and suspension body, form an annular space, tap bottom minor thread connects pump barrel, tap bottom major thread connects oil pipe, ball-and-seat is installed in the tap side, plunger upper part connects polished rod, polished rod, plunger is in the pump barrel, and plunger cooperates with pump barrel and seals, plunger and pump barrel can adopt metallic seal or nonmetal sealing, and the plunger bottom connects sucker rod.Plunger and polished rod can be made of one, and when plunger and polished rod were made of one, pump barrel was a short pump barrel.Plunger and polished rod can be hollow, satisfy the requirement of hollow rod oil pumping.Two downsides of control volume export the oil casing annular space UNICOM with oil well, the upper side outlet of control volume and the annular space UNICOM between oil pipe and the pump barrel.In order further to prevent stolen, the anti-theft type valve is installed in the outlet of control volume.
During oil pumping, plunger bottom pressure is borehole pressure, plunger upper part pressure is casing pressure, and casing pressure is generally atmospheric pressure, so, liquid comes out the back just in ball-and-seat inflow sleeve pipe from the pump barrel and the gap leaking loss between the stake plug of oil well pump in the well, making on its mouth of pumped oil well device does not need to install polished rod sealer, even thief has been closed outlet valve, because oil well pump can bear very high pressure, so the well head place can leakage of oil yet, can effectively prevent stolen and environment pollution.
The beneficial effects of the utility model are, do not need to install polished rod sealer on the mouth of pumped oil well device, have removed the work of the fastening polished rod sealer of oil recovery workman, and the molecule that can avoid theft also can prevent the pollution of the environment from the polished rod sealer stolen.

Fig. 1 is the assembling drawing of first kind of embodiment of the utility model.
Fig. 2 is the assembling drawing of second kind of embodiment of the utility model.
Fig. 3 is the assembling drawing of the third embodiment of the utility model.
Five, the specific embodiment
Below in conjunction with Fig. 1 first kind of embodiment of the utility model described.
Among Fig. 1: the 1st, polished rod, the 2nd, control volume, the 3rd, every pressure pipe, the 4th, suspension body, the 5th, ball-and-seat, the 6th, tap, the 7th, oil pipe, the 8th, pump barrel, the 9th, plunger.Be that the utility model is by light 1 bar, control volume 2, form every pressure pipe 3, suspension body 4, ball-and-seat 5, tap 6, oil pipe 7, pump barrel 8, plunger 9.Control volume 2 bottoms connect with sleeve pipe, suspension body 4 is installed in control volume 2, suspension body 4 lower link taps 6 top major threads, tap 6 top minor threads with connect every pressure pipe 3 bottoms, in pressure pipe 3 is in suspension body 4, cooperate with suspension body 4 every pressure pipe 3 tops and to seal, between pressure pipe 3 bottoms and suspension body 4, form an annular space, tap 6 bottom minor threads connect pump barrel 8, tap 6 bottom major threads connect oil pipe 7, ball-and-seat 5 is installed in tap 6 sides, plunger 9 tops connect polished rod 1, polished rod 1, plunger 9 is in the pump barrel 8, and plunger 9 cooperates with pump barrel 8 and seals, plunger 9 can adopt metallic seal or nonmetal sealing with pump barrel 8, and plunger 9 bottoms connect sucker rod.Two downsides of control volume 2 export the oil casing annular space UNICOM with oil well, the upper side outlet of control volume 2 and the annular space UNICOM between oil pipe 7 and the pump barrel.In order further to prevent stolen, the anti-theft type valve is installed in the outlet of control volume 2.During oil pumping, plunger 9 bottom pressure are borehole pressure, plunger 9 upper pressure are casing pressure, and casing pressure is generally atmospheric pressure, so, liquid comes out the back just in ball-and-seat inflow sleeve pipe from the pump barrel and the gap leaking loss between the stake plug of oil well pump in the well, making on its mouth of pumped oil well device does not need to install polished rod sealer, even thief has been closed outlet valve, because oil well pump can bear very high pressure, so the well head place can leakage of oil yet, can effectively prevent stolen and environment pollution.
