Abstract
The utility model relates to a christmas tree for a rotary oil sucking well. A well mouth joint is arranged in a rotary pipe, and the upper part of the rotary pipe is connected with a gland. An inner hole of the upper part of the gland is sheathed on the outer part of the well mouth joint, and the sealing filler, which is impacted by a seal cap, is arranged between the upper part of the rotary pipe and the well mouth joint. The outer part of the rotary pipe is provided with a bearing cap, a bearing, a bearing seat, a hanging head, a shielding sleeve from top to bottom. The christmas tree for the rotary oil sucking well can cause oil pipes to rotate, cause the entire circumference of the oil pipe to attend the abrasion, enhance the service life of the oil pipes, avoid the oil well operation after the oil pipe is locally abraded, increase the production time of the oil well and reduce the consumption cost of the oil pipe.
Description
The utility model belongs to the extracting device of oil of oil exploitation with pumpingh well, particularly a kind of rotation Production tree for pumping well.
In sucker-rod pumping system, no matter be straight well or inclined shaft, R a T all is relative motion in contact, exists inevitable wearing and tearing between sucker rod and the oil pipe.Existing Production tree for pumping well and down-hole oil tube are fixedly connected, and production tree connects with sleeve pipe again, and therefore, the position of R a T on circumference is motionless, cause oil pipe to have only the position of a side to be worn on circumference, just the eccentric wear problem.Can not use after eccentric wear is worn the oil pipe part and cause the oil well operation, increase operating cost, increase the oil pipe consumption costs, the oil well off-time is many, has reduced crude output.
The purpose of this utility model is a kind of rotation Production tree for pumping well of design, and pumpingh well oil pipe when producing can be rotated, and allows the oil pipe whole circumference all participate in wearing and tearing, avoids the oil pipe eccentric wear, thus prolongation oil pipe wearing-in period at double, the application life of improving oil pipe.
The purpose of this utility model is achieved in that it is made up of well head joint, gland, seal pressure cap, airtight and watertight padding, swivelling pipe, bearing cover, bearing, bearing support, hanging head, interstage sleeve.The well head joint is installed in the swivelling pipe, and swivelling pipe top connects with gland, and gland top inner hole sleeve is contained on the well head joint outside.In swivelling pipe top and between the well head joint airtight and watertight padding is arranged, airtight and watertight padding is compressed by seal pressure cap.The swivelling pipe outside is bearing cover, bearing, bearing support, hanging head, interstage sleeve from top to bottom.When this covering device is installed in well head, well head joint top connects the fuel-displaced mouth of pipe, and the swivelling pipe bottom connects oil pipe, and the weight of oil pipe acts on the swivelling pipe, act on then on bearing cover, bearing, bearing support, the hanging head, hanging head is installed in four-way junction of casing or the sleeve pipe threeway.When oil well production after a period of time, rotate swivelling pipe, make the oil pipe rotation, allow the abration position of oil pipe and sucker rod change, avoid oil pipe eccentric wear to occur.
Rotation Production tree for pumping well of the present utility model, pumpingh well oil pipe when producing can be rotated, allow the oil pipe whole circumference all participate in wearing and tearing, avoid the oil pipe eccentric wear, improve the application life of oil pipe, can not use the oil well operation that causes after avoiding eccentric wear that the oil pipe part is worn, reduce operating cost and oil pipe consumption costs, increase the oil well production time, increase crude output.
Accompanying drawing is the structure chart of the utility model rotation Production tree for pumping well.
Below in conjunction with accompanying drawing the utility model is described further.
In the drawings: the 1st, well head joint, the 2nd, gland, the 3rd, seal pressure cap, the 4th, airtight and watertight padding, the 5th, swivelling pipe, the 6th, bearing cover, the 7th, bearing, the 8th, bearing support, the 9th, hanging head, the 10th, interstage sleeve.Be that rotation Production tree for pumping well of the present utility model is made up of well head joint 1, gland 2, seal pressure cap 3, airtight and watertight padding 4, swivelling pipe 5, bearing cover 6, bearing 7, bearing support 8, hanging head 9, interstage sleeve 10.Well head joint 1 is installed in the swivelling pipe 5, and swivelling pipe 5 tops connect with gland 2, and gland 2 top inner hole sleeves are contained on the well head joint 1 outside.In swivelling pipe 5 tops and between the well head joint 1 airtight and watertight padding 4 is arranged, airtight and watertight padding 4 is compressed by seal pressure cap 3.Swivelling pipe 5 outsides are bearing cover 6, bearing 7, bearing support 8, hanging head 9, interstage sleeve 10 from top to bottom.When this covering device is installed in well head, well head joint 1 top connects the fuel-displaced mouth of pipe, and swivelling pipe 5 bottoms connect oil pipe, and the weight of oil pipe acts on the swivelling pipe 5, act on then on bearing cover 6, bearing 7, bearing support 8, the hanging head 9, hanging head 9 is installed in four-way junction of casing or the sleeve pipe threeway.When oil well production after a period of time, rotate swivelling pipe 5, make the oil pipe rotation, allow the abration position of oil pipe and sucker rod change, avoid oil pipe eccentric wear to occur.
