Drilling machinery and equipment in the application of the whole process, must be affected by a variety of factors to produce a variety of failures. The purpose of maintenance of drilling machinery and equipment is to reduce its application failure and ensure the normal operation of the equipment. In addition, the maintenance of drilling machinery and equipment also has another practical significance, it is to ensure the company's long-term development trend of a key project investment personal behavior. The following key analysis of the general failure of drilling machinery and equipment, and the adverse effects of this failure, and the purpose of clearly put forward several aspects of preventive measures to reduce equipment failure, for reference only.
General drilling machinery and equipment failure
The failure of drilling machine in the production and manufacture is mainly the failure of drilling machinery and equipment. According to the analysis of the construction failure of drilling machinery and equipment on the spot, the key of common mechanical equipment failure is loose type, destruction type, imbalance type, decline type and infiltration type. First, destructive faults, such as cracking, burning, cracking, contusion and crevice corrosion, etc.; Second, blocking and water leakage faults, such as water seepage, steam leakage and oil leakage, etc.; Third, characteristic fading fault modes, such as characteristic fading and overtemperature, etc.; Fourth, unbalanced faults, such as unbalanced stroke arrangement, intervention and excessive clearance, etc.; Fifth, recession faults: for example, shedding, embrittlement, and abnormal damage; six is a loose type of fault, such as loose and fall.

Adverse Effects Caused by Failure of Oil Drilling Machinery and Equipment
(I) green ecological adverse effects
In our country, the ecological environment problem is very serious. Our country's key control and manipulation of each company to avoid its production and manufacturing personal behavior that is harmful to the natural environment, so as to continue to develop in that environment. Crude oil can only ensure that machinery and equipment do not malfunction. As everyone knows, in the whole process of dealing with the problem of mechanical equipment failure in China's crude oil companies, there are certain difficulties, so that this equipment can not operate normally, resulting in serious damage to today's ecological environment protection. it is not conducive to the development of a green and environment-friendly society in our country.
(II) privacy adverse effects
Hidden faults, to put it bluntly, are equipment faults that are not easily detected. Such faults have no abnormalities in the early stage, or there are minor abnormalities that are difficult to detect. Usually, changes in time will cause indirect negative effects on mechanical equipment. For example, the equipment will be seriously damaged, the equipment will not be able to be used normally, and the serious accidents will be caused.
Adverse effects of (III) application
Applied faults are different from hidden faults. They are generally very easy to be detected. After the faults occur, there will be obvious abnormal characteristics. They can distinguish whether there are faults according to the quality, production volume and application consumption of electric energy. Such faults generally cause the equipment to be unable to be used normally, causing great confusion to the production and manufacturing of crude oil companies and other thematic activities.
Root cause of drilling machinery and equipment failure
The root cause of failure involves structural analysis, structural characterization, detection analysis, and its various courses of expertise. Therefore, under normal circumstances, the key to fault analysis is to identify the fault according to a series of steps such as on-the-spot investigation (collection of data information and application standards on the time, natural environment, sequence, etc. of the fault), analysis and clarification of the fault cause and fault principle (inspection and analysis of high-quality detection of fault parts, characteristic experiments, macroeconomic and external economic inspection of fracture surfaces, etc.) and its analysis results. In terms of drilling machinery and equipment failures, its final purpose is to identify the characteristics of the failure, search for the cause of the failure, basically identify a clear fault principle, in order to clearly put forward reasonable corrective measures. In the fault analysis, we should pay attention to the design scheme of the equipment, the selection of raw materials, the production, processing, manufacturing, installation and adjustment, application and maintenance and other countermeasures, and inquire whether there are any shortcomings.

Basic regulations on management methods and maintenance of petroleum drilling machinery and equipment
(I) Application Lubricating Fluid
Although some drilling equipment failures are inevitable, many failures can be manipulated based on the application of lubricating fluids. According to specific research, it is found that the failure of more than half of the drilling equipment is due to the failure to do a good job of moistening. Therefore, to ensure the normal application of the equipment, it is necessary to use lubricating fluid reasonably. In the whole process of the application of lubricating fluid, it must be noted that: different types of mechanical equipment, the lubricating fluid is not the same, which must be related to the staff according to the equipment structure and natural conditions, the selection of suitable lubricating fluid. In addition, it is necessary to select lubricating fluid with very good wetting effect, and to ensure that the supply of lubricating fluid can take into account the requirements of equipment maintenance and emergency treatment at ordinary times, so as to ensure that the equipment is not damaged.
(II) do a good job in the mandatory maintenance of oil drilling machinery and equipment
In the compulsory maintenance of oil drilling machinery and equipment, it is the most basic regulation to ensure the normal operation of the equipment, which requires the relevant staff to improve the normal maintenance range of the equipment to ensure that the equipment will not be abnormal. Relevant workers shall inspect the equipment on time, record the details of the equipment, immediately report some abnormal equipment, and consider solving them according to the abnormal level as appropriate. For some equipment that exceeds the service life, they shall be forcibly replaced to reduce the equipment failure problem from the source. In addition, in the mandatory maintenance of oil drilling machinery and equipment to use excellent non-destructive testing technology, do a good job of equipment failure in advance of the operation, the equipment failure damage to a minimum, for the company to save economic development assets.

(III) development of sound management practices programme
The development of a sound management method program is the same as one of the basic provisions of oil drilling machinery and equipment management methods and maintenance. The relevant staff shall formulate an effective management system according to the specific situation of the company's production and manufacturing, and the plan and scheme shall be formulated to ensure the rationalization and rationality of the management methods and methods, so as to ensure the orderly and orderly operation of the equipment during the maintenance work. For example: in the management method period of equipment oil drilling machinery and equipment spare parts warehouse, once found to have large and medium-sized machinery and equipment failure problems, it is necessary to immediately dismantle and replace parts, to prevent the oil drilling machinery and equipment shutdown rectification situation, thereby reducing the company due to maintenance damage. In addition, under the condition that the mechanical equipment components are not damaged, the technicians should disassemble and replace the mechanical equipment components in advance according to the application deadline of the components, so as to improve the quality of management.
