Compensative connector for drilling fluid pulse generator for intelligent well drilling system

Abstract

The invention discloses a compensative connector for a drilling fluid pulse generator for an intelligent well drilling system. The compensative connector comprises a connector seat, a coaxial connector, a slide sleeve, a slide rod, a spring, a spring barrel and a conversion sleeve. The connector seat is mounted at the upper end of a mud power generator and matched with the lower end of the springbarrel, and the coaxial connector is mounted in the connector seat. The lower end of the coaxial connector is connected with a pulse control driving circuit system in the mud power generator through awire. The slide rod is mounted between the spring barrel and the slide sleeve, the spring is mounted between the slide rod and the slide sleeve, and a socket of the coaxial connector is mounted in the lower end of the slide rod. In butt joint, the slide rod is capable of sliding retractably according to relative positions of the connector seat and the spring barrel to realize compensative connection. The electronic connector is protected in butt joint, disconnection and unfirm connection due to size errors are avoided, and communication connection between the pulse generator and the driving circuit system is guaranteed while reliability of the intelligent well drilling system is guaranteed. The whole compensative connector is compact in structure and convenient and simple in assembly.

Description

technical field [0001] The invention relates to the field of oil drilling equipment, in particular to a compensation connector used for a drilling fluid pulse generator of an intelligent drilling system. Background technique [0002] The drilling fluid pulse generator is an important part of the intelligent drilling system, which plays an important role in transmitting well deviation data and working parameters to the ground. The service life of the drilling fluid pulse generator is directly related to the service life of the intelligent drilling system. During the construction of the upper large-sized wellbore, the drilling fluid displacement is large, the pump pressure is high, and the sand content is high. Blockage, resulting in its inability to operate, resulting in failure of the pulse generator, which seriously affects the service life of the intelligent drilling system. Therefore, a drilling fluid pulse generator with a wide range of displacement, high signal strengt...

AI Technical Summary

Problems solved by technology

When the pulse generator sends a pulse, the main valve moves downward, and its action direction is opposite to that of the pulse generator main valve of the traditional intelligent drilling system, and the driving end of the pulse generator is located above it, while the pulse control of the current intelligent drilling system The drive circuit system is integrated in the mud generator, and its interface is also upward. In addition, due to the processing errors in the manufacturing of the mud generator, there are also assembly errors between the components of the mud generator during installation. It is difficult to ensure that each set The length of the mud generator is consistent
