Detailed Explanation of the Entire Drilling Rig Construction Process: A Clear Guide from Start to Acceptance

Step 1: Preparation (Laying the Foundation)

Before construction begins, the following preparations need to be made:

* Check if the drilling site is level and remove obstacles.

* Determine the location of the water source and underground pipelines.

* Prepare the necessary materials and tools.

* Set up safety warning signs and fencing.

Step 2: Equipment Installation (Building the Drilling Platform)

* Install the drilling rig: Transport the drilling rig to the site, fix the supports, and ensure the machine is stable.

* Connect auxiliary equipment: Install mud pumps, water pipes, cables, and other auxiliary equipment.

* Debugging and Inspection: Start-up test. Is the equipment operating normally?

Step 3: Start Drilling (Advance into the Ground)

Opening the Hole: Start drilling from the surface, initially at a slow and steady pace.

Continuous Drilling: Adjust drilling speed and pressure according to soil conditions.

Adding Protective Casing: Install casing in sections prone to collapse to prevent borehole wall collapse.

Recording Data: Record soil conditions and drilling parameters at different depths.

Step 4: Installing Well Casing and Filter Layer (Building the Well's "Skeleton")

Selecting Well Casing: Choose suitable well casing material based on well depth and water quality.

Installing Well Casing: Lower the well casing into the hole in sections and connect them securely.

Adding Filter Layer: Apply a filter layer around the well casing. Fill with appropriately sized sand and gravel to form a natural filter layer.

Step 5: Well Cleaning and Pumping Test (Cleaning and Testing)

Well Cleaning: Remove sediment and sand from the well through repeated pumping and flushing.

Water Output Measurement: Conduct continuous pumping tests, recording water level changes and stable output.

Preliminary Water Quality Observation: Check if the water is clear and free of obvious impurities.

Step 6: Completion Acceptance (Confirming Well Compliance)

Document Submission: Provide drilling records, water quality test reports, and other documents.

On-site Inspection: Acceptance personnel inspect wellhead protection, equipment installation, etc.

Functional Testing: Demonstrate pumping on-site to confirm that the output meets requirements. Requirements

Signed Documents: An acceptance report will be signed after both parties confirm compliance.

Precautions

Safety during construction: Non-staff members should not approach the work area.

Adjust construction methods promptly according to geological changes.

Keep the site clean and clear the area after construction.

Protect the wellhead to prevent debris from falling in.

Common Problems

Slow progress: May indicate encountering hard rock formations, requiring drill bit replacement or method adjustment.

Turbid water: Requires extended well washing time or inspection of the filter layer.

Insufficient water output: May indicate insufficient well depth or improper site selection.

This guide aims to help you understand the basic drilling process. In actual construction, a professional team will adjust the plan according to specific circumstances to ensure reliable well quality and long service life. If you plan to drill, it is recommended to choose an experienced construction team and fully communicate your needs before construction.
