Abstract
The utility model relates to an integrated Y junction which is characterized by comprising an integrated Y junction body made of metal material; a blanking plug locating step is arranged inside the junction body; and the junction body is also internally provided with a lower main pipe channel, a lower side pipe channel, a cable channel and a pressure meter cable channel. The utility model has the advantages that a plurality of functions are integrated into a whole, when other operations are needed in operation, only the junction is used for directly performing various operations without mounting other special tools, thus the connection of the used tools can be omitted, the operation routines is simplified, the production efficiency is improved, and the production cost can be also reduced.
Description
Technical field
The utility model belongs to the oilfield well completion technical field, particularly relates to a kind of monolithic Y joint.
Background technology
In present known completion practice, for the electric submersible pumping flow string, in order to carry out the separate zone production operation, must in tubing string, be lowered to the Y joint, traditional Y joint upper outlet connects flow string, and following side pipe connects ball-and-seat and electric pump unit, and the following person in charge connects the test side pipe.The last seating nipple of test side pipe generally all with the blanking plug of unidirectional (upwards opening), pressurizes to the liquid of pump lifting and oil pipe and to play ponding when setting the electric pump packer when completion is constructed, and can not cause and pump the liquid reflux cycle; When being lowered to the Y joint, must be lowered to and be shaped on the seating nipple that blanking plug is located step in it, can cause the multi-link excessively of instrument like this, and increase operating risk.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of be used for the oilfield well completion work production simple in structure, be convenient to operate, safe and reliable and monolithic Y joint with multiple function.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: monolithic Y joint, it is characterized in that: comprise the monolithic Y joint body of making by metal material, be shaped on a blanking plug in joint body inside and be located step, in joint body, also be shaped on and be responsible for passage, downside tube passage, cable passage and pressure gauge cable passage down.
The utility model can also adopt following technical scheme:
Described monolithic Y joint body is all made one by metal material, guarantees mechanical strength and pressure integrity.
The described passage internal diameter of being responsible for down is not for waiting gauge structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly in monolithic Y joint body, be provided with blanking plug and be located step, be responsible for outside passage and the downside tube passage down, also be shaped on cable passage and pressure gauge cable passage.The utility model gathers multi-function in integral whole, when needing in the operation to carry out other operation, need not to install other special tool realizes again, can directly carry out various operations by this joint, not only can save the connection of the instrument that is lowered to like this, simplify operation procedure, improved production efficiency, also can reduce production costs simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is A-A sectional view of Fig. 1;
Fig. 3 is B-B sectional view of Fig. 2.
Among the figure: 1, be responsible for passage down; 2, downside tube passage; 3, pressure gauge cable passage; 4, joint body; 5, blanking plug is located step; 6, cable passage.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, monolithic Y joint, comprise the monolithic Y joint body of making by metal material 4, be shaped on a blanking plug in joint body 4 inside and be located step 5, in joint body, also be shaped on and be responsible for passage 1 and downside tube passage 2 down, the described internal diameter of being responsible for down passage 1 is for waiting gauge structure, main cause under directly be shaped on blanking plug in person in charge's passage and be located step 5.For protecting cable and carrying out the bottom pressure monitoring, in joint body, also be shaped on cable passage 6 and pressure gauge cable passage 3.
Operating principle of the present utility model is: the carrier that the utility model uses is monolithic Y joint, and its upper outlet connects flow string, and downside tube passage 2 connects the electric submersible pump unit, and following person in charge's passage 1 connects the test side pipe.When being lowered to monolithic Y joint, electric submersible pump electric pump cable is connected to well head by cable passage.When needs used ground directly-reading formula electronic pressure gauge to carry out formation pressure monitoring, the pressure gauge cable can be by the pressure gauge passage continuously to well head.
Claims (3)
1. monolithic Y joint, it is characterized in that: comprise the monolithic Y joint body of making by metal material, be shaped on a blanking plug in joint body inside and be located step, in joint body, also be shaped on and be responsible for passage, downside tube passage, cable passage and pressure gauge cable passage down.
2. monolithic Y joint according to claim 1 is characterized in that: described monolithic Y joint body is all made one by metal material.
3. monolithic Y joint according to claim 1 is characterized in that: the described passage internal diameter of being responsible for down is not for waiting gauge structure.
