Abstract
The utility model a pressure test device used at a well head, which comprises a lifting coupling, a lifting sleeve, an upper central tube, a lower central tube and a pipe plug. The utility model is characterized in that a guide shoe is connected between the lifting sleeve and the upper central tube, the periphery of the guide shoe is a sealing face, and the guide shoe is provided with a water hole. The upper central tube and the lower central tube are connected through a connecting sleeve; the upper central tube and the lower central tube are respectively fixedly provided with sealed leather buckets. The utility model has the advantages that the pressure test and leak hunting can be acted on the well head components such as a blowout preventer, a contact flange, a well head flange, etc., thereby ensuring the safety when repairing the well, and reducing the environment pollution.
Description
Technical field
The utility model belongs to the corollary equipment of a kind of oil field well workover, particularly a kind of pressure testing device at well mouth.
Background technology
When the pumpingh well workover treatment, wellhead component preventer, adpting flange, wellhead flange etc. happen occasionally because installation causes leakage accidentally, exist job safety hidden danger to reach environment is polluted.
The utility model content
The purpose of this utility model provides a kind of pressure testing device at well mouth, can guarantee the safety of well workover to pressure test leak-detectings such as wellhead component preventer, adpting flange, wellhead flanges, reduces environment pollution.
The purpose of this utility model is achieved by the following technical solution: it comprises the lifting box cupling, promotes sleeve pipe, upper and lower central tube and plug, it is characterized in that: between lifting sleeve pipe and upper center tube, connect guide shoe, the guide shoe periphery is a sealing surface, have the limbers on the guide shoe, upper and lower central tube connects by adapter sleeve, fixedly installs sealing skin bucket on upper and lower central tube respectively.
Above-mentioned sealing skin bucket upper end is provided with the expansion annular groove.
The excircle of above-mentioned upper and lower central tube is provided with and seals the taper seat that the skin bucket matches.
At upper center tube and adapter sleeve junction sealing ring is set, sealing ring is set at lower center tube and plug junction.
The utility model has the advantages that: can guarantee the safety of well workover to pressure test leak-detectings such as wellhead component preventer, adpting flange, wellhead flanges, reduce environment pollution.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
See Fig. 1, the utility model concrete structure is as follows: the upper end that promotes sleeve pipe 2 is threaded and promotes box cupling 1, is promoting connection guide shoe 4 between sleeve pipe 2 and the upper center tube 6.1, and guide shoe 4 peripheries are sealing surface, have limbers 18 on the guide shoe 4.Upper and lower central tube 6.1,6.2 connects by adapter sleeve 12.Fixedly install sealing skin bucket 7 on upper and lower central tube 6.1,6.2 respectively, the excircle of upper and lower central tube 6.1,6.2 is provided with and seals the taper seat that skin bucket 7 matches.Sealing skin bucket 7 upper ends are provided with expansion annular groove 15, and the lower end is assembled in sealing by seal receptacle 8 and pushes away on the bowl 9, pushes away the bottom assembled washer 10 of bowl 9 in sealing.End thread at lower center tube 6.2 connects plug 13.In upper center tube 6.1 and adapter sleeve 12 junctions sealing ring 11 is set, sealing ring 11 is set in lower center tube 6.2 and plug 13 junctions.
Operating principle: the utility model is suspended on the well head, with high-pressure pump or pump truck by pressure testing pipe 5 in big four 17 is squeezed into press water wellhead flange 16 and sleeve pipe 14 annular spaces, seal skin bucket 7 and just the sleeve portion at pressure testing device place is sealed under hydraulic action this moment.The sealing skin bucket 7 of the utility model bottom is done the sealing of second road.Press water enters preventer 3 and adpting flange inner chamber by the limbers 18 of guide shoe, and just carry out pressure testing and leak detection to associated components and junction this moment.
