Description
Technical Field
The invention relates to the technical field of casing drilling, in particular to a torque ring group for improving the torsional property of casing threads, a mounting method of the torque ring and an assembly tool.
Background
The casing in the drilling engineering widely uses threaded connection, and threaded connection has good leakproofness, convenient and fast's assemblability and can guarantee certain intensity. However, the threaded connection part is always the weakest link of the whole pipe column part for the casing pipe column, and the screw thread failure is the main cause of most oilfield casing accidents. The damage to the tubing string due to thread failure is about 80% of the total casing failure. The casing threaded connection in casing drilling is used as a main weak link for casing string failure, alternating axial load is born while torque is transmitted, relative displacement is generated between buckling teeth, particularly in a curved well section, the casing threaded connection is subjected to the action of bending load, the separation of joint sealing surfaces of a male joint and a female joint is very easy to occur, the reduction of engagement degree is caused, the drilling accidents such as joint puncture, expansion buckle, sticking buckle and the like are caused, after drilling and completion, the casing also seals a stratum with well cementation, and high requirements are also put forward on the sealing performance of the casing threaded connection.
The rock characteristics of the drilling section are roughly cleared through a logging technology before drilling operation is implemented, the bearing torque of the casing in the drilling process is analyzed, and if the required torque is too large, the casing torque increasing measure is further considered. The torque performance of the casing string is typically improved by applying torque shoulders inside the collar, changing the thread engagement structure, and the like. The methods are relatively high in cost and not universal, a standard cannot be formed under various drilling working conditions, and an API standard oil casing is not sealed and torsion-resistant at a threaded connection part, so that most foreign casing drilling manufacturers design a special threaded connection scheme according to actual drilling working conditions. Therefore, in order to improve the exploitation effect of deep well oil field resources, the oil casing pipe meeting the API standard should not be used for a long time.
Therefore, the simple, convenient, cost-reducing and efficiency-increasing torque ring is added at the sleeve connecting part, is equivalent to the enhanced API sleeve threaded connection, and has very important practical significance in the future development of the sleeve drilling industry.

The torque ring group is correspondingly provided with a red torque ring, a yellow torque ring, a blue torque ring and a green torque ring, the length of the red torque ring is equal to the distance from the red scale belt to the standard belt, the length of the yellow torque ring is equal to the distance from the yellow scale belt to the standard belt, the length of the blue torque ring is equal to the distance from the blue scale belt to the standard belt, and the length of the green torque ring is equal to the distance from the green scale belt to the standard belt;
The sleeve is buckled to a preset position of one end in the coupling through a buckling machine, the gauge selector is penetrated into the coupling along the central axis direction of the coupling until the gauge selector abuts against the end face of the sleeve, the end face of the coupling is aligned with one of four color scale bands, and a torque ring with the same color is selected.
3. The method for installing a torque ring for improving the torsional property of a casing thread according to claim 2, wherein the preliminary installation of the torque ring specifically comprises the following steps:
The method comprises the steps of selecting a coupling for fastening a sleeve to a preset position in the coupling, and placing the selected torque ring in the coupling along the central axis direction of the coupling until the selected torque ring abuts against the end face of the sleeve, so that the selected torque ring can be initially installed.
4. A method of installing a torque ring for improving the torsional properties of a box thread according to claim 3, wherein the torque ring is further assembled by an assembly tool, comprising:
The external thread of the thread flange is in threaded connection with the internal thread of the coupling, so that the telescopic assembly is fixed on the coupling, the output end of the telescopic assembly pushes the push plate, and the push plate pushes the preliminarily installed torque ring to be abutted against the sleeve, so that the installation of the torque ring is completed.
5. The method for installing a torque ring for improving the torsional property of a casing thread according to claim 4, wherein the verifying the installation effect of the torque ring by the gauge selector comprises the following steps:
The output end of the telescopic component is retracted, the assembling tool is taken out, the gauge selector is penetrated into the coupling along the central axis direction of the coupling again to be abutted against the end face of the torque ring, and when the end face of the coupling is aligned with the standard belt, the torque ring can be confirmed to be accurately installed.
