Abstract
A kind of no-welding type cementing cement head is Cementing technology, it is formed by connecting by cement head cap, body, sealing ring, the first oily ninth of the ten Heavenly Stems, back of the body cap, backing pin, the second oily ninth of the ten Heavenly Stems, the 3rd union, lower contact back of the body cap, lower contact, be threaded on the top of body cement head cap, and centre has sealing ring to seal; Be threaded the first union on the right side of the upper end of body, and back of the body cap thread connected for the first oily ninth of the ten Heavenly Stems, and the second union is by being threaded on the right side of body lower end, and back of the body cap is threaded with the second oil the ninth of the ten Heavenly Stems; The centre of body is threaded with backing pin, and be threaded in the left side of backing pin for the 3rd oily ninth of the ten Heavenly Stems, back of the body cap is connected with the 3rd oil the ninth of the ten Heavenly Stems; Lower contact is threaded with body, and lower contact back of the body cap is threaded with lower contact.
Description
Technical field: the utility model relates to Cementing technology, especially a kind of no-welding type cementing cement head.
Background technology: in existing cementing cement head, all fluid issuings all adopt the mode of welding to be connected with main body, but this form all can cause brokenly ring to cementing head body, materials microstructure after welding around meeting butt welded seam damages, the Stability Analysis of Structures that impact is overall, cannot realize changing if the accessory of each outlet damages, there is potential safety hazard in poor reliability.
Summary of the invention: the purpose of this utility model is to provide a kind of no-welding type cementing cement head, which overcome the shortcoming that other technology exists, the purpose of this utility model realizes like this, it is formed by connecting by cement head cap, body, sealing ring, the first oily ninth of the ten Heavenly Stems, back of the body cap, backing pin, the second oily ninth of the ten Heavenly Stems, the 3rd union, lower contact back of the body cap, lower contact, be threaded on the top of body 2 cement head cap, and centre has sealing ring to seal.Be threaded the first union on the right side of the upper end of body, and back of the body cap thread connected for the first oily ninth of the ten Heavenly Stems, and the second union is by being threaded on the right side of body lower end, and back of the body cap is threaded with the second oil the ninth of the ten Heavenly Stems.The centre of body is threaded with backing pin, and be threaded in the left side of backing pin for the 3rd oily ninth of the ten Heavenly Stems, back of the body cap is connected with the 3rd oil the ninth of the ten Heavenly Stems.Lower contact is threaded with body, and lower contact back of the body cap is threaded with lower contact.
During application, cement head cap is opened, plug is loaded under in cementing head and slide on backing pin.Tighten cement head cap, the first oil is connected waterflood-transmission line the ninth of the ten Heavenly Stems, the second oil connects cementing pipeline the ninth of the ten Heavenly Stems.When well cementation starts, cement injects cement by the second oil the ninth of the ten Heavenly Stems.After cement has been noted, it is descending that clear water injects promotion cement by the first oil mouth in the ninth of the ten Heavenly Stems.
The beneficial effects of the utility model are: 1. structure is simple, safe and reliable; 2. can change the component of each outlet, improve product application life; 3. the mode be threaded can be applied to the well cementation mode of hyperpressure; 4. not broken ring cementing head bulk strength.
Accompanying drawing illustrates: Fig. 1 is a kind of structural representation of no-welding type cementing cement head, in figure 1, cement head cap 2, body 3, sealing ring 4, first oil ninth of the ten Heavenly Stems 5, back of the body cap 6. backing pin 7, second oil ninth of the ten Heavenly Stems 8, the 3rd oil ninth of the ten Heavenly Stems 9, lower contact back of the body cap 10, lower contact.
Detailed description of the invention: embodiment 1, the utility model are carried on the back cap 9, lower contact 10 be formed by connecting by cement head cap 1, body 2, sealing ring 3, first oil ninth of the ten Heavenly Stems 4, back of the body cap 5, backing pin 6, second oil ninth of the ten Heavenly Stems 7, the 3rd union 8, joint, be threaded on the top of body 2 cement head cap 1, and centre has sealing ring 3 to seal.
Embodiment 2, be threaded the first union 4 on the right side of the upper end of body 2, and back of the body cap 5 is threaded the first oil union 7 in the ninth of the ten Heavenly Stems 4, second by being threaded on the right side of body 2 lower end, and back of the body cap was threaded with the second oily ninth of the ten Heavenly Stems 7.
The centre of embodiment 3, body 2 is threaded with backing pin 6, and be threaded in the left side of backing pin 6 for the 3rd oily ninth of the ten Heavenly Stems 8, back of the body cap is connected with the 3rd oil the ninth of the ten Heavenly Stems 8.
Embodiment 4, lower contact 10 are threaded with body 2, and lower contact back of the body cap 9 is threaded with lower contact 10.
