Multifunctional full-automatic coiled tubing drilling rig

Abstract

The invention discloses a multifunctional full-automatic coiled tubing drilling rig, which comprises a main vehicle unit and an auxiliary vehicle unit, wherein the main vehicle unit comprises a vehicular chassis, a vehicular power system, a combination type derrick system and a main vehicle vehicular operation and control system; the auxiliary vehicle unit comprises a semi-mounted vehicular chassis, a drill pipe racking and moving system tubing racking part, a coiled tubing discharging and injecting system and an auxiliary vehicle vehicular operation and control system; the combination type derrick system comprises a drilling rig platform, a drill floor supporting leg, a main bracket, an auxiliary bracket, a derrick amplitude varying and posture adjusting system, a well head tubular column fastener processing system, a well head protecting system, a pinion-and-rack hoisting system, a coiled tubing injecting system and a drill pipe racking and moving system tubing moving part; the main vehicle unit can independently complete conventional single drill pipe drilling, super single drill pipe drilling and slant and vertical well drilling work; the auxiliary vehicle unit is combined with the main vehicle unit to be capable of completing a coiled tubing drilling work; the main vehicle unit cooperates with the auxiliary vehicle unit to realize single drill pipe drilling, slant and vertical well drilling and coiled tubing drilling work.

Description

technical field [0001] The present invention relates to a multifunctional fully automatic coiled tubing drilling rig, specifically a multifunctional fully automatic integrated drilling and repairing machine that can be applied to conventional single drilling, super single drilling, coiled tubing drilling, deviated well drilling and well repairing. A well device belongs to the field of petroleum equipment. Background technique [0002] According to the traditional drilling operation method, different types of drilling methods need to choose different drilling rigs to complete. For example, conventional drilling rigs are generally selected for deep vertical well drilling operations, rack and pinion drilling rigs are generally selected for horizontal well drilling operations, underbalanced drilling and old well reentry Coiled tubing drilling rigs are generally selected for operations, and professional inclined well drilling rigs are required for drilling operations in inclined ...

Problems solved by technology

[0002] According to the traditional drilling operation method, different types of drilling methods need to choose different drilling rigs to complete. For example, conventional drilling rigs are generally selected for deep vertical well drilling operations, rack and pinion drilling rigs are generally selected for horizontal well drilling operations, underbalanced drilling and old well reentry Coiled tubing drilling rigs are generally selected for operations, and professional inclined well drilling rigs are required for drilling operations in inclined and vertical wells. The frequent use of a large number of single-function drilling rigs not only increases the amount of work, wastes a lot of manpower, material and financial resources, but also the performance of the drilling rig itself cannot be obtained. Full play leads to low cost performance and increased cost. With the vigorous development of the oilfield drilling and workover equipment industry, small oil drilling rigs are developing in the direction of diversification and multi-functionality. Super single drilling rigs, inclined vertical drilling rigs and continuous Tubing drilling rigs become the future development direction of the drilling rig industry
