Description
Technical Field
The invention relates to a digital visual operation system based on oil field workover machinery operation.
Background
The minor repair operation of the oil field is the most common well repair operation mode of the oil field in China at present, has high labor intensity, poor safety and severe working environment, and is the hardest operation type of the oil field. In the middle and later periods of oil field development, the number of workover operations is increased year by year, more than 1600 underground operation teams exist in the middle petrochemical industry, and the number of annual operations is more than 13 ten thousand. The minor repair operation of the oil field is divided into minor repair operation and major repair operation, wherein the minor repair operation comprises main operations such as pump inspection, process replacement, sand washing and the like, and is the most operation form of the oil field. Simply, the workover operation which can be completed only by the lifting operation is called minor workover; the work that must be done not only by lifting but also by rotation is referred to as overhaul. At present, the minor repair operation continues a manual operation mode, a series of problems of severe operation environment, high labor intensity and the like exist, the mechanization of the minor repair operation of an oil field is always a key problem for restricting the improvement of the well repair operation efficiency and the development of the whole technology, and the research and development of a wellhead mechanization device suitable for the minor repair operation become necessary requirements of the well repair industry.
The difference of minor repair operation at home and abroad is large, the failure rate of domestic oil wells is high, the adjustment and the participation are frequent, the minor repair operation amount is large, generally accounts for 85 to 90 percent of the total number of the repair wells, and a large amount of minor repair tasks and minor repair operation teams exist. The foreign oil well has low failure rate, less parameter adjustment and small repair workload, and generally uses major repair equipment to complete minor repair tasks, and has excellent well repair equipment, long operation period and good and standard well site conditions. In addition, some foreign enterprises use full hydraulic drilling rigs as well repair equipment. Therefore, the mechanization of the domestic minor repair work is difficult to refer to and refer to foreign experiences. The small workover mechanized operation has been developed for 5 generations from the mechanization of parts of early wellhead operation, to the mechanization mode of a drilling rod based on a large workover rig for major workover, to the mechanization of wellhead oil pipe operation based on small workover equipment, to the further action mechanization mode of a person, and finally to the mechanization mode of a complete wellhead, but the mechanization mode of the complete wellhead is only a rudiment.
Mechanization of sucker rod operations remains a difficult point. The mechanization of the pumping rod is still a difficult point, mainly lies in: the traditional minor repair process still does not get rid of at present, and two actions of elevator suspension lift and slips support and bear are difficult to be taken into account in the operation of sucker rod getting up and down, and two elevator circulation modes are adopted in the operation of traditional sucker rod, but are difficult to realize in mechanized operation, and although some mechanized operation equipment adopts the mechanized equipment of simulation operation personnel, the effect is not good.
