Abstract
The utility model belongs to the technical field of application of oil production engineering, relates to an oil-water wellhead protecting cap, and solves the technical problem that a shaft is blocked by thrown foreign matters after well shutting-in. According to the technical scheme, the oil-water wellhead protecting cap is characterized in that a cap base is connected with a sleeve coupling at the upper end of the shaft in a threaded manner during application, two side shafts penetrate a wall hole of a housing, the side shafts are sleeved with a small spring and a large spring, an isolation block is arranged between the side shafts and fixed to the housing through a positioning pin, exposed parts of the side shafts are pressed into the housing, and the housing, the small spring, the large spring, the isolation block, the side shafts, and the positioning pin are seated in the cap base. The oil-water wellhead protecting cap has the advantages that a wellhead can be covered after underground well shutting-in, no part which is demountable and destructible is left outside the wellhead, the wellhead protecting cap can be extracted with special tools only, and burglar prevention and destruction prevention are good.
Description
Technical field
The utility model belongs to petroleum production engineering applied technical field, and what be specifically related to is a kind of oil-water well well head helmet.
Background technology
In oilfield process, the situation that oil well stops producing is often to occur, as it is longer to stop the well time, will shunt in a well, and use downhole hole-closure device to shunt in a well, and after shut-in well, likely in people Xiang Jing, thrown away foreign material, while having increased deblocking, need carry out the workload of wellbore treatments.
Summary of the invention
After solving shut-in well, do not thrown away this problem of foreign material obstruction pit shaft, the utility model provides a kind of oil-water well well head helmet, after the shut-in well of down-hole, well head can be sealed, and outer wellhead does not stay any component that are disassembled and destroy, only have the special tool of use just can untie the well head helmet of taking-up, there is good anti-theft and anti-damage performance.
The technical scheme in the invention for solving the technical problem is: a kind of oil-water well well head helmet is made up of housing, little spring, big spring, spacing block, side shaft, alignment pin, cap base, cap base at the casing coupling of when application and pit shaft upper end with screwed connection, side shaft is through on the cinclides of housing, little spring and big spring are enclosed within on side shaft, spacing block is clipped between two side shafts, fix with alignment pin and housing, the exposed parts of two side shafts is pressed in housing, and housing, little spring, big spring, spacing block, side shaft, alignment pin are sat and are stuck in cap base.
The beneficial effects of the utility model are, well head can be sealed, and outer wellhead do not stay any component that are disassembled and destroy after the shut-in well of down-hole, only have the special tool of use just can untie the well head helmet of taking-up, have the anti-theft and anti-damage performance of No. zero.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, formed by 1 housing, 2 little springs, 3 big springs, 4 spacing blocks, 5 side shafts, 6 alignment pins, 7 cap bases.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of oil-water well well head helmet is by housing 1, little spring 2, big spring 3, spacing block 4, side shaft 5, alignment pin 6, cap base 7 forms, cap base 7 at the casing coupling of when application and pit shaft upper end with screwed connection, side shaft 5 is through on the cinclides of housing 1, little spring 2 is enclosed within on side shaft 5 with big spring 3, spacing block 4 is clipped between two side shafts 5, fixing with housing 1 with alignment pin 6, the exposed parts of two side shafts 5 is pressed in housing 1, housing 1, little spring 2, big spring 3, spacing block 4, side shaft 5, alignment pin 6 is sat and is stuck in cap base 7.
In the time that needs take out well head helmet, must on casing coupling, fix deblocking rig floor, alignment pin 6 is bored, then the instrument that is lowered to from the hole getting out is pushed spacing block 6 aside, makes it no longer support two side shafts 5, so side shaft 5 is under the effect of little spring 2, be retracted in housing 1, make housing 1 become the cylinder without protuberance, just can in cap base 7, take out, finally lay down cap base 7 with special tool again.
