Abstract
The utility model relates to a fixing nipple for a generator flow test. The fixing nipple comprises a drill collar. The upper end of the drill collar is connected with an upper joint, and the lower end of the drill collar is connected with a lower joint. The fixing nipple is characterized in that a fixing joint is fixedly connected on the drill collar to thread a connector lug terminal of a generator and is sealed with the connector lug terminal of the generator; the fixing joint is connected with the generator via fixing pins in a circumferential fixing manner; a lead-wire upper joint is mounted on the fixing joint and is connected with a lead-wire lower joint on the sidewall of the lower joint via a bent pipe; and an output lead wire of the generator passes through the bent pipe. The fixing nipple is advantageous in that the output lead wire of the generator is led out of the drill collar so as to allow real-time dynamic supervision of generator output parameters, not only solving the problem in fixing inside the drill collar during the generator test process, but also solving the problem in leading out the output lead wire of the generator during the fluid test process; in addition, the fixing nipple has a simple structure and is convenient to maintain and operate and easy to mount.
Description
Technical field
The utility model belongs to the oilfield exploitation technical field, particularly relates to fixedly pipe nipple of a kind of generator flow test test.
Background technology
In present petroleum drilling technology field, oil field, the test of down-hole turbine generator all is to utilize the motor traction, for testing generator provides fixed rotating speed, voltage, the frequency values of test generator, thus obtain and fixed rotating speed between relation.Then, perhaps do turbine flow test, the relation between calculated flow rate and the rotating speed separately through the turbine shape.At last, obtain the voltage of flow and generator, the relation of frequency.
Because said process is the relation of measuring respectively between flow and generator speed, generator speed and voltage, the frequency, caused the link of measurement to increase, not only wasted Measuring Time, can't obtain the relation between flow and the electric current and voltage timely; And, will significantly enlarge cumulative errors through twice measurement so because each measurement links all can produce certain error.
Therefore; The development be used for installing and fixing the down-hole turbine generator and can connect the ground flow pump simultaneously with generator draw be used for the measurement; Can realize utilizing the control fluid flow directly to act on impulse turbine; Measure output voltage, the frequency of generator constantly, directly obtain the relation between fluid flow and generator voltage, the frequency, fixedly pipe nipple is extremely urgent in the generator flow test test of the accuracy of assurance measurement relation.
Summary of the invention
The utility model provides fixedly pipe nipple of a kind of generator flow test test for solving the technical problem that exists in the known technology, and this pipe nipple can realize measuring immediately the function of generator flow and electric current and voltage.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of generator flow test test is pipe nipple fixedly; Comprise the drill collar body; Drill collar body upper end is connected with top connection, and drill collar body lower end is connected with lower contact, it is characterized in that: be fixedly connected on the drill collar body and be useful on the anchor tip that installs generator wiring head end and seal with generator wiring head end; Anchor tip is connected with circumferentially fixing mode with generator through steady pin; The lead-in wire top connection also is installed on anchor tip, and the lead-in wire top connection links to each other with lead-in wire lower contact on being installed in the lower contact sidewall through bend pipe, is installed with the generator output lead in the bend pipe.
Advantage and the good effect that the utlity model has are:
After the utility model has adopted above technical scheme, generator is installed among the drill collar body, can be in the process that does not influence fluid test; The output lead of generator is drawn the drill collar body exterior; Can real-time dynamic monitoring generator output parameter, not only solve in the generator test process in the inner fixation problem of drill collar, can solve in doing the process of fluid test simultaneously; With the problem that the generator output lead is drawn, this pipe nipple is simple in structure, maintenance is easy to operate, be easy to installation.

The specific embodiment
For further understanding utility model content, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1,
A kind of generator flow test test is pipe nipple fixedly; Comprise drill collar body 2, drill collar body upper end is connected with top connection 1, and drill collar body lower end is connected with lower contact 8; Be fixedly connected on the drill collar body and be useful on the anchor tip that installs generator wiring head end 13 and seal with generator wiring head end; Its sealing is that the O RunddichtringO and the anchor tip endoporus that utilize generator wiring head end to have are realized, anchor tip 4 is connected with circumferentially fixing mode with generator 3 through steady pin 12, has two pin-and-holes on the anchor tip; Align with the notch of generator; Steady pin can insert lock-joint, and generator connector lug and anchor tip can not relatively rotate when fixing generator, and the two becomes one.
Lead-in wire top connection 7 also is installed on anchor tip; The lead-in wire top connection links to each other with lead-in wire lower contact 11 on being installed in the lower contact sidewall through bend pipe; Be installed with generator output lead 14 in the bend pipe, guarantee to flow through generator impeller at fluid, and in the process of the test of test generator each item signal of telecommunication; The sealing of generator electrical system realizes that the generator lead-in wire is present in the environment of a sealing.Bend pipe is a curved rubber hose 9 in the present embodiment, can also adopt the bend pipe of other materials as required.
Realize the circumferential location of anchor tip between said fixing joint and the drill collar body through key 5, realize the axial location of anchor tip through being installed in jump ring 6 (circlip for hole) on the drill collar inner body wall.Thereby guaranteed anchor tip do not take place axial float and and the drill collar body between relatively rotate.
The bottom of lower contact is through the outer helmet 10 that has been threaded.
The operating principle of the utility model is:
Generator is installed among the drill collar body; Can in the process that does not influence fluid test, the output lead of generator be drawn the drill collar body exterior, constantly dynamic monitoring generator output parameter; Not only solve in the generator test process in the inner fixation problem of drill collar; Can solve in doing the process of fluid test simultaneously, the problem that the generator output lead is drawn, and simple in structure, maintenance is easy to operate, be easy to install.
