Embodiment Construction

[0014] The present invention will be further described below in conjunction with example:

[0015] The carbon fiber continuous flexible sucker rod operation equipment of this application includes two arc-shaped plates 11, which are arranged in parallel, and the setting of the two arc-shaped plates 11 determines the trajectory of the carbon fiber sucker rod 17 running on it It is an arc-shaped track, which ensures the smooth transition of the carbon fiber sucker rod 17 from the horizontal direction to the vertical direction. The bottom plate 7 is fixed between the two ends of the arc-shaped plate 11, and the support plate 6 is fixed between the bottom plate 7 and the arc-shaped plate 11. , the bottom plate 7 and the support plate 6 play the role of fixing and supporting the two arc-shaped plates 11, and the rotating shaft 8 is evenly spaced between the two arc-shaped plates 11, and the outer wall of the rotating shaft 8 is covered with a rubber sleeve 9, and the rotating shaft ...

Abstract

The invention provides carbon fiber flexible continuous sucker rod operation equipment which comprises two arc-shaped plates arranged in parallel. A bottom plate is fixed between the two ends of each arc-shaped plate, supporting plates are fixed between each bottom plate and the corresponding arc-shaped plate, and rotating shafts are evenly arranged between the two arc-shaped plates at intervals. The outer walls of the rotating shafts are sleeved with rubber sleeves with the arc-shaped surfaces. A support is hinged to one ends of the two arc-shaped plates, and adjusting screws are connected to the lower ends of two supporting rods of the support correspondingly. The other ends of the two arc-shaped plates are fixedly connected with an operation frame which is inserted into a rotating base, and the rotating base is mounted on the well mouth. By means of the operation equipment, it can be guaranteed that a carbon fiber flexible continuous sucker rod can be smoothly taken off, stress concentration caused by mechanical abrasion on the carbon fiber flexible continuous sucker rod operation equipment is avoided, and the service life of the equipment is prolonged; and by the adoption of the equipment, the carbon fiber flexible continuous sucker rod is protected against plastic deformation during operation, and normal use of the carbon fiber flexible continuous sucker rod operation equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oil production in oil fields, and in particular relates to a carbon fiber continuous flexible sucker rod operation equipment. Background technique [0002] The sucker rod is a kind of equipment commonly used in the oil production process. During oil production, the pump rod of the downhole oil pump is driven to reciprocate up and down by the sucker rod, so as to pump the oil and other liquids in the formation to the ground. During use, it is usually necessary to connect the sucker rod to thousands of meters. In this case, the sucker rod has to bear its own suspension weight and the load of the oil pump, so it bears a relatively large pulling force. Carbon fiber continuous sucker rod, this kind of sucker rod is made of carbon fiber with light weight, good toughness, high tensile strength and other superior physical properties, and this sucker rod has torque resistance and wear resistance. Therefore, when ...
