Abstract
The utility model relates to a flexible rotary combined instrument for logging well in the oil field, which is composed of an upper joint, a rotary outer cylinder, a rotary ring, a rotary joint, a flexible rotary outer cylinder, a flexible short pitch outer cylinder, a flexible seal joint, and a lower joint; the combined instrument is added with the flexible rotary joint and the improved flexible seal joint basing on the flexible short pitch and the rotary short pitch so as to form a whole; the upper joint is thread-connected with the rotary outer cylinder, the rotary ring is arranged in the rotary outer cylinder and sleeved on the shaft of the rotary joint, the rotary joint is thread-connected with the flexible rotary outer cylinder, the flexible rotary outer cylinder and the flexible rotary conversion joint. The flexible seal joint is sleeved into the flexible short pitch outer cylinder, the flexible short pitch outer cylinder is thread-connected with the lower joint. The combined instrument solves the problem that the two instruments existed in the prior art can not be connected together so as to bring great installation difficulty due to climate and environmental limitation. The utility model can be widely applied for well logging operations in oil field.
Description
Technical field:
The utility model relates to the flexibility rotation combination instrument that a kind of oil reservoir logging is used.
Background technology:
The difficult problem of oil reservoir logging technology existence at present is that logger is long, and particularly one runs into the corner frangibility.Introduced flexible pipe nipple and rotating short-knot from the U.S., these two kinds of appliance requires are installed at the scene for this reason, owing to be subjected to weather and environmental limit, have brought very big difficulty to installation.We have carried out improving on two kinds of pipe nipple bases of introducing and have been developed into flexible rotation combination instrument, and it is by new component the two organically to be connected into integral body to have solved problems of the prior art.This combination instrument meets in the process of going into the well that flecition can be played in the corner in order to avoid the crooked ambassador of mistake logging instrument fractures.
The utility model content:
The purpose of this utility model is to provide a kind of flexible rotation combination instrument, and it has solved two kinds of instruments that exist in the prior art can not be connected in one owing to be subjected to weather and environmental limitations to bring the problem of very big difficulty to installation.
The technical scheme that novel its technical problem of solution of this reality is adopted is: flexible rotation combination instrument is made up of top connection, rotation urceolus, rotating ring, swivel joint, flexible rotation urceolus, flexible rotation crossover sub, flexible pipe nipple urceolus, flexible sealing joint, lower contact; This combination instrument has been set up flexible rotation crossover sub and has been constituted one with improving the flexible sealing joint on flexible pipe nipple and rotating short-knot basis; Top connection is threaded with the rotation urceolus, with rotating ring be installed in the rotation urceolus in and with its be enclosed within swivel joint the axle on, swivel joint is with flexible rotation crossover sub with flexible rotation urceolus, flexible rotation urceolus and is threaded, the flexible sealing joint is packed in the flexible pipe nipple urceolus, and flexible pipe nipple urceolus is threaded with lower contact.
The beneficial effects of the utility model are, flexible pipe nipple and rotating short-knot link into an integrated entity and have two kinds of instrumental functions, and structure is simpler, and it is convenient to reduce the tool interface system site operation, has improved the instrument security performance.
