Description
Technical Field
The invention belongs to the technical field of nondestructive testing of gas storage wells, and particularly relates to a cable winding and unwinding device of a gas storage well detection system and a control method.
Background
At present, CNG gas stations mainly provide gas sources for urban public transportation and are built in densely populated cities. The gas storage well is a tubular facility which is vertically buried underground, is sealed by cement slurry between a shaft and a well wall and is used for storing compressed gas, and belongs to the category of fixed pressure containers and the variety of high pressure containers. The gas storage well consists of a shaft, a wellhead device and a well bottom device. The gas storage well works in a cyclic inflation and deflation process, mainly bears alternating internal pressure load, the pressure range is generally between 10 and 25MPa, the pressure fluctuation is more than 20%, and the total number of designed pressure cycles is generally 25000. The nominal pressure of the gas storage well is generally 25MPa (gauge pressure), the nominal volume of the gas storage well is 1-10 m 3, and the inner diameter of the shaft is 177.8mm and 244.48 mm.
The gas storage well is made of high-strength steel and has threaded connection and section change, so fatigue analysis is adopted in design. Although the gas storage well is deeply buried in the ground, the gas storage well has the advantages of high safety and small explosion risk, the gas storage well still has the damage tendency including instability, fatigue, corrosion (including medium corrosion and environment corrosion), rigidity failure (screw sealing failure) and the like, and serious accidents of bursting the well shaft and flushing out the ground can also occur. Because the gas storage well of the gas station has the characteristics of large reserves, high pressure, high frequency, large pressure change and the like, the method is very important for the periodical inspection of the gas storage well of the CNG gas station.
The main equipment for periodic inspection is a well bore wall thickness corrosion detection system which comprises an operable controller, a cable drum winch, a ground pulley, a crown block, a wellhead frame and an ultrasonic probe which are designed in a split mode. During detection, the cable reel winch, the ground pulley and the wellhead frame are fixed first, the crown block is arranged at the upper end of the wellhead frame, the cable is wound on the reel, one end of the cable is wound around the crown block and then enters the gas storage well, so that the wellhead section cable is in a vertical state, the wellhead section cable is located at the axis position of the gas storage well, and the accuracy of a detection result is ensured. Every time, the installation position of the wellhead frame is required to be adjusted according to the position of the gas storage well and the diameter size of the wellhead, then the gas storage well is fastened, meanwhile, the relative positions of the cable drum winch, the ground pulley, the crown block and the wellhead frame are required to be ensured to be stable in the detection process, the gas storage well cannot move, and otherwise the detection accuracy is influenced. Such operations are complex, cumbersome, inefficient, costly, and have relatively low detection accuracy. Therefore, a cable winding and unwinding device of the gas storage well detection system with simple structure and convenient operation needs to be designed.
