Basic classification and common problems of drilling rigs_oil drilling rig manufacturers

Drilling rig is a mechanical equipment for drilling holes on the surface. It can be a large outdoor water well, oil well, natural gas well drilling equipment, or a single mobile small equipment, called an auger. Drilling rigs can be used to sample underground deposits or to install underground production equipment, such as underground machines, instruments, pipelines and hoistways. It can be mobile equipment mounted on trucks, trailers, tracks, or more fixed installations on land or offshore structures (such as drilling platforms, commonly referred to as "offshore oil rigs", although they are not designed to contain rigs). The term "drilling rig" generally refers to equipment that drills through the Earth's crust.

Basic parameters of oil drilling rigs_oil drilling rig manufacturers

Oil drilling rigs generally have eight major systems (lifting system, rotating system, drilling fluid circulation system, transmission system, control system and monitoring and display instrument, power drive system, drilling rig substructure, drilling rig auxiliary equipment system), and shall have tripping capacity, rotary drilling capacity and circulating flushing capacity. Its main equipment includes: derrick, overhead crane, winch, traveling block, hook, rotary table, faucet (power faucet) and drilling pump (the site is customarily called eight parts of drilling rig), power machine (diesel engine, electric motor, gas turbine), linkage machine, solid control equipment, well control equipment, etc.

Workover operation method, system and process_workover rig manufacturer

After the oil well is put into production, the casing in the oil well may be blocked and the inner diameter becomes smaller, which will cause some production tools to be unable to be lowered into the oil well through the casing, thus causing the oil well to fail to produce normally. In this case, it is necessary to carry out a workover operation, that is, to repair the well casing. In the workover operation, it is necessary to use the drilling tool to mill the casing to remove the casing blockage and expand the inner diameter of the casing, so as to ensure that the production tool can be lowered into the oil well through the casing.

How does the drilling machine work during drilling?

Under the effect of atmospheric pressure, the circulating liquid flows from the accumulation tank to the bottom of the well hole along the annular gap of the well hole through the backwater ditch. Since the rotary table at this moment drives the drill pipe and drives the drill bit to rotate for drilling, the negative pressure established by the mud pump sucks the debris mud into the inner cavity of the drill pipe, then rises to the tap and discharges into the accumulation tank through the mud pump. The accumulated circulating liquid continues to flow into the well hole.

Selection method of down-the-hole drilling rig_oil drilling rig

The selection of the down-the-hole drilling rig mainly considers several factors: the aperture, depth, direction, angle and drilling accuracy of the engineering hole, the rock condition, the condition of the construction site, the construction period, etc. Then according to these requirements to match the appropriate drilling rig, and supporting its corresponding air compressor. At present, large, medium, type, high, medium and low wind pressure, crawler walking and rubber wheel walking are widely used in the domestic market. The driving power includes diesel engines, electric motors, wind motors and other models.

Maintenance of Drilling Rig Pneumatic Control System_Oil Drilling Rig Manufacturer

The pneumatic valve body has another feature: it has been working well during continuous use, but it suddenly failed after a few days of use. This situation is more likely to occur on dual-use relays. This is because the valve cavity will produce rust during the deactivation period, which will increase the assistance of the valve movement department, and cause air leakage due to work failure. Only the spool repeated activities several times can be normal work. If the leakage continues, the valve must be opened instead to check the reason. When the drilling rig after a well or after a certain period of time (the longest should not exceed 3 months), the entire gas control system should be a maintenance, a comprehensive inspection of the wearing parts, so that timely replacement after cleaning, to avoid the valve in an abnormal state of work.

Classification of oil drilling

Oil drilling is divided into exploration wells and production wells according to the purpose of drilling. According to the well trajectory can be divided into vertical wells and directional wells. According to the environmental conditions of drilling operations, it is divided into onshore drilling and offshore drilling. According to the well depth, it can be divided into shallow well, medium-deep well, deep well, ultra-deep well, ultra-deep well and so on.

Integrated Design and Application of Truck-mounted Drilling Rig

The truck-mounted drilling rig integrates the power system, drawworks, derrick, traveling system and transmission system into the self-propelled chassis, and relies on its own power to realize the lifting, lowering and recovery of the derrick, and uses the same set of power system to realize the chassis driving after the drilling is completed. By optimizing the design of the components of the truck-mounted drilling rig, the supporting equipment is integrated into the car platform, which greatly reduces the number of transport vehicles and the workload of installation and disassembly in the relocation process, greatly improves the relocation efficiency of the drilling rig, while reducing transportation costs and increasing the reliability of the drilling rig.

Maintenance of Drilling Rig Pneumatic Control System_Oil Drilling Rig Manufacturer

The normal operation of the gas control system must ensure the supply of a certain amount and pressure of compressed air, otherwise there will be an accident of insufficient output due to wrong action. Therefore, there may be air leakage sound. After shutdown, engage all clutches, and the pipeline pressure drop shall be within the allowable range. For ZJ130-3 drilling rig, when the compressed air pressure is not lower than 9 atm, the pressure drop shall not exceed 1 atm for 30min.

What is the difference between workover rig and truck-mounted drilling rig_workover rig manufacturer

Drilling rig is mainly used for drilling; workover rig is mainly used for oil, water, gas wells for a variety of maintenance operations. Of course, the function of the equipment is not very clear, because the drilling rig can also be used for workover operations, especially for deep wells and ultra-deep wells. Some workover rigs equipped with drill discs can also be used for drilling operations. Of course, due to the limited lifting load and power, only some relatively shallow wells can be drilled.
