Abstract
The utility model relates to a flexible connector, which is used for drilling tools conveying in the well logging construction, and belongs to the technical field of geophysical well logging process in oil-gas exploration. The flexible connector is provided with a steel pipe with a straight hole, seven S-shaped texture holes are cut on the pipe wall of the steel pipe by lines at equal intervals, and threaded binding heads are arranged at two ends of the steel pipe. Through the design, the connector has properties of being flexible, pliable and telescopic. In construction, the flexible connector is assembled between abutting tools, so that the flexibility of the abutting tools is increased, and the abutting tools can change along with the well curvature, therefore, the problems of falling and breaking of the abutting tools during the conventional drilling tool conveying in the well logging construction can be solved.
Description
Technical field
The utility model relates to used flexible connector in a kind of well logging construction at inclined shaft, horizontal well (using the drilling tool conveying well measuring that bonding tool is docked with the downhole logging instrument device), belongs to geophysical log technology field in the oil-gas exploration.
Background technology
At present the drilling tool conveying well measuring used to whole hard connection of bonding tool growing (5 meters), when construction operation enters big gradient and net horizontal section, bonding tool is subjected to the influence of heterodyne in drill string vibration, down-hole pressure and the drilling tool, will cause bonding tool is come off or loses.And bonding tool is come off and loses, will cause the male and female contact pin ground connection sparking of wet joint, burn out insulating layer, the well logging construction can't be continued, have only trip-out, change the wet joint assembly again and, cause drilling tool conveying well measuring time lengthening and cost of production to increase bonding tool.
Summary of the invention
Bonding tool is come off and lose problem in order to solve drilling tool conveying well measuring instrument, the utility model has designed flexible connector.Its technical scheme is: designed flexible connector has the steel pipe that straight hole is arranged in, uniformly-spaced cuts out 7 " S " type pits with line on the steel pipe tube wall, and the steel pipe two ends are threaded connector.Implement in the structure, with external diameter is φ 43mm, and internal diameter is that the steel pipe of φ 15mm cuts out 7 " S " type pits with line, makes steel pipe can be arbitrarily crooked (according to the flexibility requirement thereby reach, can increase or reduce " S " line bar number) purpose, can reach simultaneously flexible and flexible purpose.When construction this flexible connector connect between bonding tool, because of flexible connector can be crooked arbitrarily, so have the performance that is flexible coupling, can make bonding tool can be changed with the variation of hole curvature in well, so just solved the drilling tool conveying well measuring effectively to bonding tool coming off and lose problem in big gradient and horizontal well well section, shorten the well logging engineering time and reduced cost of production, improved the one-time success rate that inclined shaft, horizontal wellbore logging are constructed.
Description of drawings:
Fig. 1: the structural representation of flexible connector described in the utility model.
Fig. 2: the schematic diagram of " S " type pit on the steel pipe tube wall.
The specific embodiment
Referring to accompanying drawing, this flexible connector has the steel pipe that straight hole is arranged in, uniformly-spaced cuts out 7 " S " type pits with line on the steel pipe tube wall, and the steel pipe two ends are threaded connector.The external diameter of steel pipe is that φ 43mm, internal diameter are φ 15mm.In the real work, with flexible connector and make bonding tool is connected firmly, connect weighted lever according to the horizontal well hole curvature again, the weighted lever overall weight is pressed on the bonding tool; Finish connect go into the well after, can change with hole curvature bonding tool, solved effectively bonding tool come off or loses problem.
