80% of the problems of workover machinery and equipment occur during the opening of the workover operation. Due to the problems caused by the wear of parts, the workover operation procedure is complicated, and fine cooperation between various parts is required to proceed smoothly. Only a problem with one part in the workover operation can prevent the workover operation from opening smoothly. Therefore, in the selection of parts to choose regular manufacturers and safety assurance information, in the selection of machinery to have advanced production technology and planning scientific and reasonable machinery. In addition, there is a need to ensure smooth machinery and careful operation of workover personnel. First of all, to ensure that the machinery is reasonably smooth. One of the reasons for the problem of workover machinery is the problem caused by wear and tear, and the other is caused by unreasonable smoothness. To ensure the smooth implementation of workover machinery requires not only the fine cooperation of various parts, but also reasonable smoothness. Smoothness can prevent some dust from entering the inside of the machinery and damaging the parts, and can also keep the temperature of the parts within the normal scale and ensure the normal operation clearance of the parts.
Therefore, the rational use of smoothing agent has a significant effect on the smooth implementation of workover operations. Relevant personnel in the selection of smooth agent, according to the actual workover machinery structure, operating environment, season reasonable selection of smooth agent model, must not change the model and purchase no safety guarantee of fake and inferior products: together with carefully check the quantity of smooth agent in the warehouse, in order to make up for in time. Secondly, the need for workover personnel scientific operation of machinery. Workover personnel only scientific operation, to be able to reduce the mechanical problems caused by man-made reasons. Before performing workover operations, carefully check whether the coolant and oil of the machine are sufficient. To ensure that the machine enters the low-speed preheating stage, and the machine can only start operation after the coolant and oil reach the specified temperature. During the operation of the workover rig, the operator should check the value of the mechanical thermometer at any time. It is strictly forbidden to overload the machine at low temperature. Once the problem is found, it should be solved in time to reduce the wear of the machine and reduce the occurrence of problems.
Emergency methods for defects in workover rig
The workover rig is at the pioneer site of the oil field. Due to the difficulties of accessories, materials and hoisting equipment, the repairers are required to fully demonstrate their intelligence and skills to eliminate the defects of oil drilling machinery and equipment as soon as possible. The on-site emergency repair methods of workover rig include: 1) parts repair method: machine processing, welding, grinding and other methods are used to quickly modify damaged parts.
2) Replacement of parts with or instead of patching method Replace the damaged parts with spare parts without defects, which can be selected during overhaul and on-site repair. Together, the materials around can be used to replace the damaged parts and components. The parts placement method throws away the parts that have been blocked, and the workover rig tries to connect the pipelines or circuits to quickly regulate the production of drilling machinery and equipment.
