Coiled tubing drilling machine roller transport vehicle

Abstract

The invention discloses a coiled tubing drilling machine roller transport vehicle and relates to the field of oil and gas field self-propelled coiled tubing drilling equipment. The coiled tubing drilling machine roller transport vehicle comprises a vehicle frame, a coiled tubing roller, a power system, a transmission system, a rear axle, a cab and a front axle, wherein the vehicle frame comprisesa first vehicle frame section, a second vehicle frame section in a rectangular frame shape and a third vehicle frame section, the second vehicle frame section is located between the first vehicle frame section and the third vehicle frame section and comprises a first crossbeam, a second crossbeam, a first vertical beam and a second vertical beam, the first vertical beam and the second vertical beam are connected between the two ends of the first crossbeam and the two ends of the second crossbeam, the first vehicle frame section is connected with the first vertical beam, and the second vehicleframe section is connected with the second vertical beam; the coiled tubing roller is arranged on the second vehicle frame section; the power system, the transmission system and the rear axle are arranged on the third vehicle frame section, and the power system is used for driving the rear axle and a hydraulic pump of the coiled tubing roller; and the cab and the front axle are arranged on the first vehicle frame section. The coiled tubing drilling machine roller transport vehicle can solve the problems that existing roller twined coiled tubing is insufficient in capacity and poor in road passing performance.

Description

technical field [0001] The invention relates to the field of self-propelled coiled tubing drilling equipment in oil and gas fields, in particular to a roller transport vehicle for coiled tubing drilling rigs. Background technique [0002] The coiled tubing machine is called a universal machine, and it is widely used in field operations in oil and gas fields. With the continuous development of coiled tubing operation technology, coiled tubing drilling technology has gradually matured. Coiled tubing drilling requires large-diameter and long-sized coiled tubing, which leads to continuous increase in the size of coiled tubing rig drums and makes transportation of coiled tubing rig drums difficult. [0003] At present, the conventional second-class chassis vehicles, the engine is basically the front, and the power is transmitted to the rear axle through the transmission shaft. Due to the existence of the transmission shaft, the sinking of the drum is affected, and the capacity o...

Coiled tubing drilling requires large-diameter and long-sized coiled tubing, which leads to the continuous increase in the size of the coiled tubing rig drum, making it difficult to transport the coiled tubing rig drum

[0003] At present, the conventional second-class chassis vehicles, the engine is basically the front, and the power is transmitted to the rear axle through the transmission shaft. Due to the existence of the transmission shaft, the sinking of the drum is affected, and the capacity of the drum cannot be increased; while the semi-trailer is used to transport the drum , although the capacity of the drum can be increased as much as possible, but due to the self-limitation of the climbing performance and turning radius of the semi-trailer, it is often difficult to meet the conditions of the oil field roads in hilly and mountainous areas.
