Abstract
The utility model belongs to the technical field of logging-while-drilling tools, and relates to a suspended drill collar unit device for test of a three-parameter logging-while-drilling tool. An inner cavity of one end of a suspended drill collar is connected with a pressure plate and a tensioning ring, the other ends of the pressure plate and the tension ring are connected with a bearing seat which is connected with a connecting sleeve and a transition taper, the other end of the transition taper is connected with a power nipper, and the other end of the power nipple is connected with a flexible connector. The suspended drill collar unit device has the advantages that use of a pulse generator and MWD (measurement whiling drilling) needed during testing is reduced, test and maintenance are facilitated, reliability in measurement of the tool is guaranteed, and production, research and development costs of the while-drilling tool are saved.
Description
Technical field
The utility model relates to a kind of three parameter logging while drilling apparatus tests and hangs drill collar cell arrangement, belongs to logging while drilling apparatus technical field.
Background technology
At present, in the development process of three parameter logging while drilling apparatuses, when needs field trial, be all generally to adopt three parameter logging while drilling apparatuses and mud pulse generator, MWD to be connected into the mode of a system, so that the directional data in drilling process and geologic data are uploaded in real time.Accident and mud pulse generator, the fault of MWD and the fault that connects of three parameter logging while drilling apparatuses that this connecting mode can mud pulse generator, MWD occur in process of the test are taken in the test of three parameter logging while drilling apparatuses, thereby affect the result of the test of three parameter logging while drilling apparatuses.
When three parameter logging while drilling apparatuses are tested, be mainly to test for the function of instrument itself, do not need real-time Transmission geologic parameter data, the data of surveying temporarily poke in instrument, after pulling out of hole, instrument is taken out, sense data is analyzed.Three parameter logging while drilling apparatus tests are hung drill collar unit and can normally be connected with drilling rod in the part near drill bit, and measurement result adopts the mode of storage.Thereby the impact of the connection fault of having avoided impulse generator, MWD fault and their threes on measurement result.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of three parameter logging while drilling apparatus tests to hang drill collar cell arrangement.
Drill collar cell arrangement is hung in a kind of three parameter logging while drilling apparatus tests, one end inner chamber that hangs drill collar connects platen and tensioning ring, the other end connecting axle bearing of platen and tensioning ring, bearing support is connected with excessive cone with adapter sleeve, excessively the other end of cone connects power supply pipe nipple, and the other end of power supply pipe nipple connects flexible connector.
The utility model has the advantages that impulse generator required while having reduced test, the use of MWD, be convenient to test and safeguard, guaranteed the reliability of apparatus measures, saved with the R&D and production cost that bores instrument.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, drill collar cell arrangement is hung in a kind of three parameter logging while drilling apparatus tests, one end inner chamber that hangs drill collar 1 connects platen 2 and tensioning ring 3, the other end connecting axle bearing 4 of platen 2 and tensioning ring 3, bearing support 4 is connected with excessive cone 6 with adapter sleeve 5, excessively the other end of cone 6 connects power supply pipe nipple 7, and the other end of power supply pipe nipple 7 connects flexible connector 8.
For solve three parameter logging while drilling apparatuses when testing due to the impact on measurement result of impulse generator, MWD fault and their threes' connection fault, unit indoor design location, mud overcurrent, suspension, power supply, the structure such as flexibly connect, the utility model top can be connected easily with drilling rod or drill collar, the utility model bottom can with three parameter logging while drilling apparatuses of various structures and size fast, connect reliably.
Through with boring instrument in the medium many-sided test of practical logging operation process, verified that the utility model both simplified the structure of downhole instrument, be convenient to dismounting and safeguard, met again the instructions for use under the adverse circumstances of down-hole, guaranteed the reliability of instrument.
Use at the scene Shi，Xian ground that assembly of the present utility model is assembled in order, then first suspension drill collar is hung to raised platform around a well and connect with three parameter logging instruments suspension drill collars.Next the utility model assembly being connected is lifted into and hangs drill collar top, then slowly from hanging drill collar, put into, finally instrument suspension assembly is held out against and hanging drill collar sidewall.After connecing whole connections, instrument just can normally have been gone into the well.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
