Abstract
The utility model relates to a full-sealed anti-theft christmas tree, which is composed of a standard christmas tree and a high intensity protective housing. The protective housing and the christmas tree are assembled into a sealed integral structure through an inner connecting plate. The utility model has the advantages of high strength, breakage prevention, and good performance. Because a flow path crater is arranged on th christmas tree, the installation is convenient, the security of an antitheft door is good, the antitheft door is easy to open, and the normal oil production work is convenient. The utility model is especially suitable for a 250 type christmas tree.
Description
The utility model relates to a kind of total closed type anti-theft oil-production tree that is applicable to that the land production wellhead uses, and particularly is applicable to the 250 model production tree.
Oil, stolen the reaching by the production tree stolen of natural gas production wellhead facility are the serious problems that oil play faces, and it is perplexing the ordinary production of enterprise.Standard 250 model production tree is the widely used a kind of production wellhead of present nonflowing well, its greatest problem be outdoor nobody look after under the environment destroyed easily, and from the destruction stolen, main stolen mode is to turn on plug or back out pressure gauge crude oil is released, and also can drain the oil by valve.The local protection of common employing solves the stolen problem, soon easily turns on partly to be difficult for turning on partly with other to weld.Though this can stop stolen, for operate as normal has been brought difficulty, the well head easily initiation fire of getting angry also simultaneously.Installing the integral protection cover additional for production tree is another kind of theft preventing method, and still, at present scene, the well site technology of production tree that is welded varies the production tree size, and therefore, this has brought difficulty for installing the closed protective cover additional, causes this technology to implement on a large scale.
The purpose of this utility model provides a kind of total closed type anti-theft oil-production tree of uniform specification, and it can prevent stolen effectively, makes things convenient for normal operation simultaneously again.
The purpose of this utility model is achieved in that the total closed type anti-theft oil-production tree is made up of standard production tree and closed theft-proof box, the standard production tree is linked to be by clip and oil pipe short circuit by the connection oil pipe of flange, big four, valve, plug, rubber gate and unified specification, thereby realized neither changing former oil recovery flow process, again the purpose of unified production tree size.Protective housing is made up of preceding casing, rear box, casing shroud, plug cover, rubber valve cover five parts, the convenient security door of opening of one fan is arranged on the preceding casing, security door is by the coded lock locking that is mounted thereon, be assembled on the production tree by Nei Lianka and connecting plate each several part, form a whole closed structure theft-proof box.This makes production tree both have whole theftproof performance, can carry out normal operation by opening security door again simultaneously.
Concrete structure of the present utility model is provided by following examples and accompanying drawing 1-4 thereof.
Fig. 1 is according to the total closed type anti-theft oil-production tree vertical view that the utility model proposes.
Fig. 2 is the sectional drawing along A-A line among Fig. 1.
Fig. 3 is the sectional view along B-B line among Fig. 1.
Fig. 4 is the sectional view along C-C line among Fig. 2.
The label implication is in the accompanying drawing: 1 clip, and 2 connect oil pipe, and 3 rubber valves, 4 big fours reach goes up lower flange, 5 valves, 6 oil pipe short circuits, 7 plugs, 8 reserve the flow process welded pipe, 9 preceding casings, 10 rear box, 11 plug covers, 12 rubber valve covers, 13 sleeve pipe valve bonnets, 14 security doors, 15 Nei Lianka, 16 door-hinges, 17 coded locks, 18 Nei Lianka, 19 connecting bolts.
Total closed type anti-theft oil-production tree of the present utility model comprises standard production tree and protective housing two parts, and wherein the standard production tree reaches last lower flange (4), valve (5), oil pipe short circuit (6), plug (7) by clip (1), connection oil pipe (2), rubber gate (3), big four and reserves flow process welded pipe (8) and form.Big four reaches to go up lower flange (4), valve (5), plug (7), rubber gate (3), connection oil pipe (2) and reserve flow process welded pipe (8) and is assembled into the standard production tree by clip (1) and oil pipe short circuit (6).Protective housing is made up of preceding casing (9), rear box (10), plug cover (11), rubber gate cover (12), sleeve pipe valve bonnet (13) and security door (14).Rear box (10) is connected production tree by Nei Lianka (18) by connecting bolt (19) and connects on the oil pipe (2), preceding casing (9) is connected with rear box (10) by interior connecting plate (15), security door (14) is loaded on the preceding casing (9) by door-hinge (16), coded lock (17) is installed on the security door (14), rubber gate cover (12) sleeve pipe valve bonnet is connected on preceding casing (9) and the rear box (10) by interior connecting plate (15) respectively, after so connecting, production tree is closed by protective housing, and protective housing self constitutes a totally-enclosed case structure.
Standard production tree in the utility model can be the 250 model production tree, and it is modular prefabricated, the thick 5～8mm of the steel plate of each precast segment of protective housing.The following describes the installation and the course of work of the utility model total closed type anti-theft oil-production tree.
The utility model only need be opened security door the lower flange of production tree is connected on the sleeve pipe, will reserve flow process welded pipe (8) and weld with the oil return pipeline and promptly finish installation.The reservation flow process welded pipe of the utility model total closed type anti-theft oil-production tree is convenient installs.Production tree and protective housing are standard component, and interchangeability is strong, the whole good leak tightness of protective housing, and the intensity height, the anti-theft effect ideal, the unlatching coded lock is opened security door and can be carried out routine work.
