Abstract
The invention relates to a multifunctional pressure releasing adjustor that is made up of water faucet sealing ring, water faucet, and water faucet pressure thread, water faucet base sealing ring, water faucet base, and bulkhead sealing ring, bulkhead, joint, thread protector, and case. The invention has good adjusting effect to the pressure and relief flow rate in the water injection well pressure releasing process. It adds well mouth interface and has cut-off function.
Description
One, technical field: the invention belongs to petroleum gas petroleum production engineering device, especially multifunction pressure releasing regulator for water injection well
Two, background technology: the well head water injection pressure is called as high-pressure water injection well greater than the water injection well of 25Mpa, and at present the ratio of Zhongyuan Oil Field high-pressure water injection well surpasses 50%, part well well head water injection pressure even be higher than 40Mpa.Because workover treatment is generally carried out under passive state, therefore, high-pressure water injection well all will experience the pressure process of putting before workover treatment, and indivedual wells were put the pressure time above 3 months.Pressure is too quickly to damage stratum, down-hole string and ground sewage recovery line for fear of putting, and water injection well is put and all adopted the control of well head gate to put pressure when pressing, and its harm mainly contains three aspects: the one, and pressure reduction is big before and after the gate, easily stings bad gate board; The 2nd, can't accurately regulate and control; The 3rd, in case out of control, will cause serious consequence.
Three, summary of the invention: the purpose of this invention is to provide and strengthen water injection well and put pressure and spillway discharge regulation and control in the pressure process, it is too quickly to the stratum to avoid putting pressure, down-hole string and ground sewage recovery line damage, expand the multifunction pressure releasing regulator for water injection well of water injection well function simultaneously, it has solved the problem that present other technology exists, the object of the present invention is achieved like this, it is by the water nozzle sealing ring, water nozzle, the water nozzle silk pressing, water nozzle seat sealing ring, the water nozzle seat, the plug sealing ring, plug, joint, thread protector, housing is formed by connecting, overlapping water nozzle sealing ring and integral body on the water nozzle is embedded in the water nozzle seat, there is the water nozzle silk pressing water nozzle back, and water nozzle silk pressing and water nozzle seat are by screwed connection; Water nozzle seat and housing are by screwed connection, and there is the sealing of water nozzle seat sealing ring at water nozzle seat rear portion; Housing and joint weld together; Thread protector is enclosed within the afterbody of housing and by screwed connection; The plug sealing ring is enclosed within on the plug, and the afterbody of plug and housing is by screwed connection.
Pressure and spillway discharge that the present invention is put in the pressure process water injection well have played regulating action preferably, have increased the well head interface simultaneously, and have had by function, and on-the-spot result of use is obvious.
Four, description of drawings: Fig. 1 is the structural representation of multifunction pressure releasing regulator for water injection well, among the figure 1, water nozzle sealing ring 2, water nozzle 3, water nozzle silk pressing 4, water nozzle seat sealing ring 5, water nozzle seat 6, plug sealing ring 7, plug 8, joint 9, thread protector 10, housing
Five, the specific embodiment: in Fig. 1, overlapping water nozzle sealing ring 1 and integral body on the water nozzle 2 and be embedded in the water nozzle seat 5, there is water nozzle silk pressing 3 water nozzle 2 back, and water nozzle silk pressing 3 and water nozzle seat 5 are by screwed connection; Water nozzle seat 5 and housing 10 are by screwed connection, and there are 4 sealings of water nozzle seat sealing ring at water nozzle seat 5 rear portions; Housing 10 welds together with joint 8; Thread protector 9 is enclosed within the afterbody of housing 10 and by screwed connection; Plug sealing ring 6 is enclosed within on the plug 7, and the afterbody of plug 7 and housing 10 is by screwed connection.
