Problems solved by technology

[0004] The purpose of the present invention is to provide a coiled tubing roller device to overcome the problems of the existing technology that the coiled tubing capacity is small and the transmission torque is small or the transmission is not stable when the size requirements of the transportation operation are met. Under the premise of transportation operation requirements, the coiled tubing winding amount can be increased while the transmission torque is large and the low speed is stable

Abstract

The present invention discloses a coiled tubing reel device and a coiled tubing vehicle. The coiled tubing reel device comprises a reel body assembly (1) configured to wind a coiled tubing and a driving component (2) configured to drive the reel body assembly (1), wherein, the reel body assembly (1) comprises a reel body (11), a reel shaft (12), a transmission gear (13), and a first bearing block(14) and a second bearing block (15) that are oppositely arranged and spaced from each other, wherein the reel body (11) is fixedly fitted on the reel shaft (12), and the two ends of the reel shaft (12) are rotatably arranged on the first bearing block (14) and the second bearing block (15) respectively. The coiled tubing reel device and coiled tubing vehicle provided in the present invention canincrease the coiled tubing winding capacity, provide high transmission torque, and operate smoothly and steadily at a low speed, while meeting the requirement for transportation dimension.

Description

technical field [0001] The invention relates to the field of oil exploitation equipment, in particular to a coiled tubing drum device and a coiled tubing operation vehicle. Background technique [0002] With the continuous development of coiled tubing technology, the application of coiled tubing technology to solve the operation needs of deep wells and ultra-deep wells is becoming more and more urgent and more and more. Halliburton has used variable outer diameter coiled tubing technology to increase the maximum vertical operating depth to over 10,000m; Schlumberger and other companies have a large number of successful cases of coiled tubing deep wells and ultra-deep wells with operating depths exceeding 6,000m. However, the large-diameter coiled tubing drums used by these companies are super large, super wide, and super high. For example, the coiled tubing drum with an outer diameter of 2″ and a capacity of 7,600 m can reach 4.5 m, which cannot meet the conditions of limite...
