After the completion of the well, it is necessary to pump water to check the results. Under normal circumstances, it is only necessary to pump water once. The stable duration of the water level shall not be less than 8 hours. At the same time, the outlet flow of the dynamic water level of the well shall be measured. For large wells with water inflow at the bottom of the well, the thickness of the inverted filter layer and the particle size of the filter material shall be constructed in accordance with the design requirements. The mud and sediment at the bottom of the well must be removed before the inverted filter layer is laid. The filter material shall be sieved to remove mud and measured for standby.

Attention to water exploration and discharge of full hydraulic tunnel drilling rig

When the drilling rig is close to the old empty hole and it is expected that there may be gas or other harmful gas gushing out, there must be a gas inspector or mine rescue team on duty to check the air composition. If the gas or other harmful gases exceed the relevant provisions of the "Coal Mine Safety Regulations", the drilling rig must be stopped immediately, the power supply must be cut off, the personnel must be withdrawn, and the mine dispatching room must be reported to take measures to deal with it in time.

Precautions for Operation of Small Water Well Drilling Rig

After drilling the drill bit of the agricultural drilling machine, it is necessary to replace the central drilling tool in time. First, you need to clean the bottom of the hole, and then blow off the residue at the bottom of the hole. After the drill bit stops rotating, the drill bit in the agricultural drilling machine is drilled out. With a gentle upward lift, it is suitable when the lifting force is just enough to lift the drill bit.

Inspection Items of Drilling Rig_Oil Drilling Rig Manufacturer

Drilling rig is a complex machine, which consists of machines, units and institutions. Drilling rig is in the exploration or mineral resources (including solid ore, liquid ore, gas ore, etc.) development, drive the drilling tool to drill underground, access to physical geological data of mechanical equipment. Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole and lower or raise the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc. to explore underground geology and mineral resources.

Advantages of Anti-well Drilling Rig Application_Oil Drilling Rig Manufacturer

According to the design requirements of the hole, the pillar is firmly erected. The upper and lower ends of the pillars shall be covered with planks. The horizontal shaft and snap ring are installed on the pillar according to a certain height and direction. Lift the machine through a manual winch, fix it on the pillar at the desired angle, and then adjust the hole of the drill bit.

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.
