Abstract
The utility model relates to a cored flexible nipple for horizontal well logging, which consists of an upper casing, a lower casing, an inserting hole, an upper sealed protective segment, a lower sealed protective segment, a male connector, a female connector, a core wire and an insert pin. The upper sealed protective segment and the lower sealed protective segment are respectively arranged in the upper casing and the lower casing, the male connector and the female connector are arranged between the upper sealed protective segment and the lower sealed protective segment, the upper sealed protective segment and the lower sealed protective segment are integrally connected by the male connector and the female connector, the core wire is disposed in the upper sealed protective segment and the lower sealed protective segment, the inserting hole is arranged at the upper end of the core wire, and the insert pin is arranged at the lower end thereof. The flexible nipple is novel in structure and reliable in operation, can be utilized to resolve actual production problems in highly-deviated well tests for casings, increases testing success ratio and facilitates normal work of centered instruments.
Description
Technical field:
The utility model relates to a kind of sleeve in oil field well performance that is used for and tests the particularly downhole testing instrument fastening means of high angle hole, horizontal well dynamic test.
Background technology:
Flexible pipe nipple is used for the downhole tool that the logger polyphone connects when being oil field high angle hole, horizontal well dynamic test.At present, the on-the-spot flexible pipe nipple that adopts usually is rubbing property of the ￠ 38mm pipe nipple that did not have core, its link position has limitation, can't realize the power supply and the signal transmission of each instrument in the tester string, inapplicable cable real-time Transmission test, and multi-parameter dynamic tester string is made up of many ￠ 38mm instruments and weighted lever, and length greatly and employing is hard between the instrument connects, and pliability is poor.When carrying out the cased well dynamic test, sleeve pipe or tubing string often exist reducing or distortion, the tester string is by reducing, distortion place the time, take place easily the instrument string can't by or be stuck in phenomenon such as somewhere, cause the test success rate lower, so that engineering accident takes place, simultaneously when carrying out the high angle hole dynamic test, because the tester string is heavier, be unfavorable for the tester string is set upright between two parties, for when testing, setting upright difficulty placed in the middle, influence the precision of test data at the instrument of center condition work.
The utility model content:
The purpose of this utility model is to provide a kind of can solve the problem not having the flexible pipe nipple of core and exist when the cased well dynamic test, guarantee the cased well dynamic test particularly the high angle hole dynamic test carry out smoothly and the horizontal wellbore logging of the data testing accuracy flexible pipe nipple of core.
The utility model is to realize like this.The flexible pipe nipple of this kind is made up of upper and lower casing, upper and lower seal protection section, connection male and female head, mistake heart yearn, contact pin, jack; its structure, assembled relation are as follows: be respectively equipped with upper and lower seal protection section in the upper and lower casing; being provided with connection male and female head between the upper and lower seal protection section connects as one the two; be provided with heart yearn in the upper and lower seal protection section; cross the heart yearn upper end and be provided with jack, the lower end is provided with contact pin.During test, should pass through on it by the flexibility pipe nipple, on on the lower house, lower contact is connected the optional position in the tester string, the lower contact of top tester is connected with the top connection of flexible pipe nipple, the contact pin of instrument is inserted jack, the lower contact of flexible pipe nipple is connected with below tester top connection, and the contact pin of flexible pipe nipple is inserted the jack of instrument, particularly high angle hole of cased well can carried out, improve the pliability of tester during the horizontal well dynamic test, reduce effectively the tester string in the process of removing can't by or be stuck in the probability in somewhere, improve the test success rate, avoid contingent engineering accident, also can help the operate as normal of instrument placed in the middle simultaneously with requiring the weight of tester placed in the middle front and back instrument to share.The flexible pipe nipple of this kind is free deflection 12 degree axially, crossing heart yearn is communicated with jack with contact pin, make the instrument of upper/lower terminal can carry out communication, can be connected optional position in the tester, do not influence the power supply and the signal transmission of each instrument in the tester string, help carrying out smoothly of logging operation.
The utility model novel structure, reliable operation utilizes it can solve production practical problem in the test of cased well and high angle hole, improves the test success rate, and helps the operate as normal of instrument placed in the middle.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
As shown in the figure, the utility model by upper shell 1, lower house 5, jack 3, go up seal protection section 4, lower seal protection section 9, connect male 6, connect female 7, cross heart yearn 8, contact pin 11 is formed.Wherein, upper shell 1, lower house 5 are two pipe bodies that external diameter is identical, and upper shell 1 upper end is provided with tapped top connection 2, and lower house 5 is provided with interconnective connection male 6 and is connected female 7, and the lower end is provided with is with externally threaded lower contact 8.Last seal section 4, lower seal protection section 9 are for being provided with and protecting the double-deck body of heart yearn 8 usefulness.Cross heart yearn 8 for making of high temperature resistant material, have flexible lead, bonding with high temperature resistant special glue and seal protection section, its upper end is provided with jack 3, and the lower end is provided with contact pin 11.
