Lubrication and Maintenance of Petroleum Drilling Machinery and Equipment

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.

How to choose and buy truck-mounted drilling rig

For the preparation of materials in advance, you need to show your ID card, residence booklet, marriage certificate (single person can go to the local public security bureau to issue a certificate of unmarried), proof of funds (if you really don't have it, you can consider raising the down payment), proof of personal income (if you really don't have it, you can make an ideal way to buy a house). If you buy a house in full, you only need to show your ID card and residence booklet;

Method for maintenance of drilling machine by drilling personnel

The drilling machine must do an all-round maintenance work every month. The actual practice is to fully carry out all the inspection items of daily maintenance. Remove the printer ink cartridge, clean the slips and slips, and replace them immediately if there is any damage. Clean the filter device and replace the gear oil to prevent mildew. Check the detailed key components. If the long-term damage is serious, replace new spare parts immediately. Summary of the problems found by drilling industrial equipment that month, immediately contact the factory professional and technical personnel to develop a relative maintenance plan. If the drilling equipment has not been used for a period of time, the appearance of the hood and pipe should be coated with salt-free butter or anti-rust oil.

Hydraulic drilling machine drill pipe users how to maintain

There are four "forbidden" standards in the case of maintenance of hydraulic water well drilling rigs: 1. Drill pipes and drill bits are only used for drilling pile holes, and it is forbidden to use them in the same work as the migration, transportation or construction site consolidation of the soil layer. Never allow the drill bit to penetrate into the liquid concrete. And only when the drill bit touches the bottom of the hole can the actual operation just start drilling.

Rotary drilling rig maintenance

Maintenance of rotary drilling machine Today, I led everyone to master the maintenance of rotary worktable of rotary drilling machine. I think everyone knows the person responsible for the rights of the rotary drilling rig and should also know its efficacy. Rotary table output great torque and working pressure, but it also bear the load, vibration, impact, so the rotary table is a rotary excavator. The core component is also the most problematic component. So, let's revisit today's topic of discussion.

Basic requirements for management and maintenance of petroleum drilling machinery and equipment

Doing a good job in the mandatory maintenance of oil drilling industrial equipment is the most basic regulation to ensure the normal operation of all machinery and equipment, which requires the relevant workers to improve the normal maintenance range of machinery and equipment to ensure that there will be no abnormalities in machinery and equipment. Relevant workers should carry out inspection on the machinery and equipment on time, and keep a good record of the details of the machinery and equipment. They should immediately report some abnormal machinery and equipment, and consider solving them according to the abnormal level. They should be forced to replace some machinery and equipment that have exceeded the service life, so as to reduce the common fault problems of the machinery and equipment from the source. In addition, in the oil drilling industry equipment mandatory maintenance work to use excellent non-destructive testing technology, do a good job of common failure of machinery and equipment in advance of the operation, the common failure of machinery and equipment damage to minimize, for the company to save economic development assets.

Brief introduction of petroleum popular science oil drilling rig

The derrick and base are used to support and install various drilling equipment and tools and provide drilling operation site. The derrick is used to install the overhead crane, suspension traveling machine, hook, faucet and drilling tool, bear the drilling load and discharge the stand; the base is used to install the power unit, winch, rotary table and support the derrick, and the rotary table is used to suspend the drilling tool to provide a high space between the rotary table and the ground to install necessary BOP and facilitate mud circulation.

Measures for Improving Drilling Speed of Drilling Rig

From the point of view of rotary drilling, in order to improve the drilling speed, we should mainly increase the rock breaking energy of the drill bit at the bottom of the rock, and improve the two factors of weight on bit and speed. Because the technical improvement of bit pressure and speed will be limited by many factors, the technical ability at this stage is mainly to improve the speed. There are two main ways to increase the rotation speed: on the one hand, increasing the rotation speed of the rotary table or using the top drive device, and on the other hand, using the compound drilling technology of downhole power drilling tools and low-speed rotating drill string. However, the first method is limited by the strength of the drilling tool and the energy of the drilling rig, and the speed increase is limited. The composite drilling technology of PDC downhole power drilling tool can give full play to the characteristics of PDC bit suitable for high speed shearing formation, greatly improve the PDC bit speed and mechanical rock breaking energy, so as to improve the mechanical drilling speed.

Common problems and treatment methods of drilling rig

It is determined to include small formation inclination force and formation inclination force, scoop angle, weight on bit, formation inclination angle, drilling machine bit anisotropy index, formation anisotropy index, well bore orientation and fire angle of formation inclination orientation. The formation coclinotectic force may be a build-up force or a down-slope force, and the formation azimuthal change force may be an increasing azimuthal force or a decreasing azimuthal force. In general, the formation deviation force makes the drill bit trajectory close to the formation normal direction, and the formation change azimuth force makes the borehole azimuth close to the formation inclination azimuth. When the borehole azimuth of the drilling machine is consistent with the formation inclination azimuth, the formation variable azimuth force is zero.

Factors Affecting the Speed of Drilling Machinery in Drilling Engineering

In deeper formations, the drillability is poor due to the greater hardness of the rock layer. With the increase of depth, the drillability level is higher, and the drillability also changes according to the different geological structure of each layer. In deeper well sections, due to high temperature and pressure, the level of drillability will increase. In the strata containing mudstone and argillaceous sandstone, due to the change of elasticity, plasticity and brittleness, the difficulty of crushing is increased. In the sand-mudstone interbedding and containing gravel layer, the phenomenon of drilling will also occur, which will reduce the service life of drilling tools and affect the speed of drilling machinery.
