Drilling rig with intelligent flexible pipe

Abstract

The invention relates to a drilling rig with an intelligent flexible pipe, which mainly comprises a winding drum, the intelligent flexible pipe, a pulley mounting bracket, a pulley, a quick male joint, a quick female joint, a junction box crossover joint, a junction box, a measuring instrument crossover joint, a measuring instrument, a well bottom motor crossover joint, a well bottom motor and a drill bit. The drilling rig is characterized in that the wall of the flexible pipe is internally provided with at least two signal lines and a power line; the quick male joint is provided with a measuring box in which a data acquisition unit is arranged, and the data acquisition unit is correspondingly connected with a data display through the signal lines. The drilling rig is simple in structure, convenient to mount and dismount, easy to maintain, capable of reducing the labor intensity of operating personnel and increasing the efficiency and low drilling cost; and a winch type intelligent flexible pipe drilling technology is realized, and a physical channel for power transmission and information transmission is constructed between a well bottom and the earth surface so as to realize power transmission and signal transmission.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drilling device with an intelligent flexible pipe. Background technique [0002] With the continuous increase of drilling depth, the proportion of drilling and drilling time has increased significantly, and the energy and equipment losses caused by the friction between the drill pipe and the hole wall are also increasing. The information is unpredictable, so that accidents in the hole occur frequently. [0003] For flexible pipe technology, foreign countries have developed and put into production flexible pipe drilling rigs, whose power is mud circulating fluid; for intelligent drill pipes, Yuan Pengbin of Shanghai Hilong Petroleum Pipe Research Institute published an article in 2010, saying that it has successfully trial-produced two 101.6mm×9.14m intelligent drill pipe, which achieves the goal of transmitting power to the bottom of the hole, but does not realize the winch-type intelligen...
