During the operation of the equipment, a qualitative change in the state of parts and assemblies occurs, caused by the wear of interconnected working surfaces. It is impossible to completely avoid equipment wear. However, the correct operation of drilling equipment, the use of high-quality lubricants and maintenance systems helps to extend the overhaul period of the equipment.
The system of maintenance and scheduled repair of drilling equipment provides for a number of regulated operations contained in GOST 18322-78.
Maintenance- a set of operations or an operation to maintain the operability or serviceability of the product when used for its intended purpose, waiting, storing and transporting. It contains operations regulated in the design documentation to maintain the operability or serviceability of the product during its service life. Maintenance may include washing the product, monitoring its technical condition, cleaning, lubricating, fixing bolted joints, replacing some components, and adjusting.
Repair - a set of operations to restore the serviceability or performance of products and restore the resources of products or their components. Repair may include disassembly, control of the technical condition of the product, restoration of parts, assembly, etc. the content of some repair operations may coincide with the content of some maintenance operations. Repair of any kind must be accompanied by the issuance of certain guarantees for the subsequent period of operation.
The basis for carrying out high-quality and timely repairs is the maintenance and repair system. (maintenance and scheduled repairs). This system consists of the following main sections: the system of maintenance and scheduled repairs, the structure and duration of repair cycles and the overhaul period, the organization of operational and technical accounting and reporting. Maintenance and repair of equipment is carried out after determining the period of its operation. The alternation and frequency of maintenance and repair are determined by the duration of the overhaul period of each unit that is part of the installation.
The maintenance and repair system establishes the fundamental foundations for organizing them, which creates the necessary prerequisites for more efficient use of equipment, an increase in the overhaul period, a decrease in the intensity of wear of mating parts, and provides the possibility of more thorough preparation repair work, carrying them out in the shortest possible time and at a high technical level. Planning, preparation and organization of maintenance and repair work are aimed at carrying them out as soon as possible and at minimal cost. Technological preparation consists in the development of technical conditions for overhaul, technological processes for disassembly, assembly, restoration and compilation of defective statements.
The organization of repair work includes the planning of repair work, the technical preparation of production, the use of advanced repair technologies, the mechanization of locksmith and assembly work, the development of repair specialization by type of equipment, the expansion of the scope of the aggregate and in-line repair method, and the provision of repair documentation.
The maintenance and repair system for drilling equipment operating in the oil industry provides for maintenance (TO), current repairs (TR), overhaul (CR).
Maintenance (TO)- is divided into two types - periodic and seasonal. Periodic maintenance is carried out after the values of operating time or time interval established in the operational documentation (for example, TO 1, TO 2, TO 3). Seasonal maintenance includes operations to replace seasonal oils, install or remove insulation, preheating units, etc. Maintenance of the equipment is carried out by the operating personnel of the drilling rig or by the repair team. The results of maintenance are recorded in the journal. The maintenance complex is regulated by the instructions of the manufacturers.
Maintenance (TR) carried out during operation in order to ensure the guaranteed operation of the equipment. During TR, partial disassembly of equipment, repair of individual components or replacement of worn parts, adjustment and testing in accordance with the operating instructions are carried out. Faulty parts and assemblies are repaired in workshops. TR is carried out by repair teams with the involvement of maintenance personnel in accordance with the plans.
Capital repairs (KR) carried out in order to restore the operability and resource of the equipment. The complete disassembly of the equipment, washing and defectoscopy of parts, repair, adjustment, assembly, load testing and painting are carried out during the KR. KR is carried out in accordance with the repair schedule at specialized plants equipped with the appropriate technological equipment. The order of delivery for repair, testing and acceptance after repair are determined by the technical conditions for the overhaul of equipment.
The organization of maintenance and repair is carried out under the methodological and technical guidance of the chief mechanic service. Practical implementation is assigned to the production service bases, centralized repair plants.
Thus, the current system of maintenance and repair of equipment provides for a set of preventive measures aimed at maintaining equipment in constant operational readiness and ensuring the highest performance and high quality drilling operations, increase overhaul periods of service, reduce the cost of repair and operation of equipment, improve the quality of repair work.
The list of operations performed during the passage of Technical Maintenance in the "RSV service":
