Embodiment Construction
[0020] The tripping control system for workover operation of the present invention includes two parts: a software system and a hardware system.
[0021] Among them, the hardware system includes PLC controller, servo motor, servo motor controller, foot switch, proximity switch and some intermediate relays. Among them, the PLC controller adopts Siemens 224CN plus EM221 expansion module, which has a total of 30 points of input and 10 points of output; the programming software uses Siemens V4.0STEP 7 MicroWIN SP9; the servo motor driver adopts Hyde's H3N-FD, the servo motor model It is ACSM130-G15015LZ; the foot switch adopts the structure of two keys in one, one of which is a working key, and the other is an emergency stop key; the proximity switch adopts PNP type, and its sensing distance is 8mm; the intermediate relay adopts Deli West JQX-13F small relay.
[0022] The software system includes the two functions of tripping and tripping in. Specifically, when tripping, the PLC c...

The invention discloses a tripping control system for workover operation. The tripping control system comprises a mechanical arm arranged at an oil well, and further comprises a foot switch, wherein the mechanical arm is connected with a servo motor and further connected with a PLC controller; a sensor is arranged on the mechanical arm; the PLC controller comprises a rotation control switch for controlling the rotating direction of the mechanical arm, a parameter pointer rotating when an oil pipe is placed, a parameter pointer extending outside when the oil pipe is placed, an oil-pipe placing counter for counting trip-out numbers, clockwise-rotation parameters and counterclockwise-rotation parameters, used for controlling the rotating direction of the mechanical arm while performing trip-in operation, of a trip-in positioned sampling pipe, length parameters of the mechanical arm extending outside when the trip-in positioned sampling pipe clockwise rotates, length parameters of the mechanical arm extending when the trip-in positioned sampling pipe counterclockwise rotates, and the well-mouth center distance for controlling the action position of the mechanical arm when performing trip-in operation. The tripping control system disclosed by the invention is high in degree of automation, so that the automatic trip-out and trip-in operations can be realized, and the working strength and danger of workers are reduced.
Description
technical field [0001] The present invention relates to the technical field of workover equipment, in particular to a tripping control system capable of realizing automatic tripping and tripping, which can use machinery to replace manual operations on oil pipes, greatly reducing the work intensity and dangerous. Background technique [0002] Well workover operation refers to a kind of operation of oil drilling and subsequent oil well maintenance, in order to ensure the smooth use of oil wells, maintenance and maintenance measures are taken. Workover operations are characterized by high engineering difficulty and high technical requirements. Large workover equipment must be equipped with special equipment and tools such as overhaul drill pipes and overhaul turntables to carry out work. In the workover operation in the prior art, the most common work content includes tripping out and tripping in. Drilling, as the name suggests, is to lift the downhole drilling tool (such as ...
