Abstract
The utility model provides a direction adjusting sub for a combination logging, which comprises a body. A first joint and a second joint are respectively arranged at two ends of the body, a first joint as a male joint is connected with a first instrument in a matching manner, a locking nut used for locking the first instrument is further connected onto the first joint, the locking nut is rotatably arranged on the body, the second joint is a female joint, one end of the second joint is connected with a second instrument in a matching manner while the other end is rotatably arranged on the body, and a fixing ring fixing the second joint onto the body is further arranged on the second joint. The direction adjusting sub realizes adjustment and determination of the angle and position relationship of the first instrument and the second instrument by adopting the first joint and the second joint to be respectively connected with the first instrument and the second instrument and fixing the first joint and the second joint respectively via the locking nut and the fixing ring, also improves angle and position overlap ration of a pushing arm in the combination logging, and accordingly greatly enhances quality of the combination logging.
Description
Technical field
The utility model relates to a kind of tuning pipe nipple that is used for combination logging.
Background technology
When downhole probe carries out combination logging, because many instruments that have backup arm are not thought association, be easy to make a plurality of backup arms can produce the position difference, backup arm and borehole wall loose contact are good when causing combination logging.Backup arm contacts effect with the borehole wall and is affected, and influences work such as setting of instrument, will produce worse influence to the quality that obtains well-log information.
At present, instruments such as density commonly used and microballoon carry out combination logging, because instruments such as density and microballoon lack the location adjusting in the process of going into the well, thereby inconsistent phenomenon take place, and finally cause some gap of obtained curve and ideal curve.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can improve combined instrument backup arm angle position registration, thereby improves the device of combination logging quality.
In order to address the above problem, the utility model provides a kind of tuning pipe nipple that is used for combination logging, comprising:
Body, described body two ends are respectively arranged with first joint and second joint;
First joint, described first joint is male joint, is connected with first instrument, also is connected with the locking nut that is used to lock described first instrument on described first joint, described locking nut is rotatable to be arranged on the described body;
Second joint, described second joint is female joint, and described second joint, one end and second instrument are connected, and the other end is rotatable to be arranged on the described body, also is provided with on described second joint described second joint is fixed on retainer ring on the described body.
Further, between described second joint and the described body by being threaded.
Further, described first joint and described body are integrally formed.
Further, described body, first joint, second joint, locking nut and retainer ring are titanium alloy material.
The utlity model has following advantage:
1, adopt first joint to be connected first instrument and second instrument respectively in the utility model with second joint, and fix first joint, second joint by locking nut and retainer ring respectively, concern thereby realize adjusting with determining first instrument and the second instrument angle position, also just improve backup arm angle position registration in the combination logging, thereby improved the quality of combination logging greatly.
2, in the utility model, body, first joint, second joint, locking nut and retainer ring are titanium alloy material, utilize titanium alloy can bear the performance of HTHP, improve pressure bearing and seal performance of the present utility model greatly, thereby improve the reliability of the utility model in the combination logging process.
3, the utility model is simple in structure, reliable, highly versatile, the cheap and handled easily use of the utility model cost of manufacture.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 shows a kind of tuning pipe nipple structural representation that is used for combination logging of the utility model;
Fig. 2 shows a kind of tuning pipe nipple user mode schematic diagram that is used for combination logging of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises body 1, first joint 2 and second joint 3.Wherein, body 1 is a main body of the present utility model, is cylindrical-shaped structure.Be respectively arranged with first joint 2 and second joint 3 at the two ends of body 1.
Adopt first joint 2 to be connected first instrument 6 and second instrument 7 respectively in the utility model with second joint 3, and fix first joint 2, second joint 3 by locking nut 4 and retainer ring 5 respectively, concern thereby realize adjusting with determining first instrument 6 and second instrument, 7 angle positions, also just improve backup arm angle position registration in the combination logging, thereby improved the quality of combination logging greatly.
In the utility model, between second joint 3 and the body 1 by being threaded.Rotate this screw thread and just can regulate angle position relation between second joint 3 and the body 1, because second joint 3 fixedlys connected with second instrument 7, thereby by this screw thread of rotation, the position of adjusting easily between second instrument 7 and the body 1 concerns.
In the utility model, first joint 2 is integrally formed with body 1.Adopt this form, convenient making moulding of the present utility model.
In the utility model, body 1, first joint 2, second joint 3, locking nut 4 are titanium alloy material with retainer ring 5.Body 1, first joint 2, second joint 3, locking nut 4 are titanium alloy material with retainer ring 5, utilize titanium alloy can bear the performance of HTHP, improve pressure bearing and seal performance of the present utility model greatly, thereby improve the reliability of the utility model in the combination logging process.
The utility model is simple in structure, reliable, highly versatile, the cheap and handled easily use of the utility model cost of manufacture.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
