Drilling a 200-meter deep water well is a relatively complex engineering task that requires specific equipment to complete. Below is a list of necessary equipment compiled based on the provided search results:
Drilling equipment
Drilling Rig: Track-type engineering drilling rig or fully hydraulic drive power head type drilling rig, suitable for large tonnage pre-stressed anchor holes or drainage hole construction in rock and soil engineering such as hydropower stations, railway, highway slopes, etc., as well as ground source heat pump hole construction, etc. For example, Binzhou BZCCD350ZY type drilling rig and BW850/2A mud pump.
Drilling Tools: including a Φ393.7mm rotary bit and a Φ159×4.5m drill collar for the first-stage hole formation; a Φ593.7mm rotary bit and a Φ159×4.5m drill collar for the second-stage hole enlargement.
Filter Sleeve: Bridge-type filter sleeve, durable with large porosity, size Φ273mm × 6mm, bridge hole gap 0.75~1mm.
Filter Media: 5-7 mm pebbles.
Boring Tools for Opening Holes: This includes the opening drill bit and drilling mud, ensuring that the hole is drilled vertically without collapse. Initially, low drilling pressure, low rotation speed, and medium pump volume are used for drilling. Once the process is normal, conventional drilling parameters are adopted, with high drilling pressure, medium rotation speed, and large pump volume.
Installation and maintenance of equipment
Installation of Submersible Pumps: After the drilling and well-making processes are completed, submersible pumps need to be installed to extract groundwater.
Mud Control System: This includes a mud storage tank and a mud pump, which are used to control and discharge the mud.
Text: Venue Decoration and Auxiliary Equipment
Site Layout: There needs to be sufficient space to accommodate the drilling rig and other equipment, as well as the setup of a circulation system, a secondary pit, and a mud reserve pit.
Auxiliary Equipment: This includes water wheels and cranes, which are used for transporting materials and equipment, as well as for other auxiliary tasks in site management and construction work.
The above equipment is compiled based on the specific content mentioned in the search results. For detailed information about the device models and supplier information, further consultation with professional construction units or equipment providers may be required. It should also be noted that in practical operations, adjustments to the selection and configuration of equipment may need to be made according to geological conditions and engineering requirements.
