Introduction to Deep Well Construction 1. Medium sized deep wells are made of PVC plastic pipes with a diameter of 160 millimeters and a drilling diameter of 300 millimeters. The surrounding area between the holes is filled with yellow sand, with a depth of 40-150 meters and a flow rate of 5-70 tons per hour. 2. Large deep wells are made of high-pressure cement pipes with a diameter of 360 millimeters and a drilling diameter of 600 millimeters. The surrounding area between the holes is filled with quartz sand, with a depth of 100-500 meters and a flow rate of 10-100 tons per hour. Deep wells are widely used in printing and dyeing, electroplating, chemical industry, rubber and plastic industry, mechanical cooling, animal husbandry, and daily drinking. Drilling is a project that involves the joint operation of multiple trades using various equipment, tools, and materials. It is also a continuous operation with multiple programs closely connected and multiple links interlocked. All constructions have considerable complexity. The completion of each well includes three stages: pre drilling engineering, drilling engineering, and completion operation. Each stage of the project involves a series of construction procedures. The main processes generally include: well positioning, road survey, foundation construction, installation of wellhead, moving, equipment installation, primary drilling, secondary drilling, drilling, lifting, drill bit replacement, drilling, completion, electrical measurement, casing installation, cementing operations, etc.

Improper operation and too fast drilling speed can generate significant excitement and pressure. Easy to cause leakage in the formation, and too fast drilling speed can generate significant suction force. Easy to pump out oil and gas reservoirs or collapse structural formations. Especially in the case of drill bits or stabilizers with mud bags, it is serious. Thirdly, drilling equipment malfunctions. Stopping the movement of drilling tools or the circulation of drilling fluid is a common factor in underground accidents. Weakness in work, failure to follow regulations, and failure to read tables (such as weight gauges, pump pressure gauges, and torque gauges).

The cut soil chips fall into the pot and are discharged on the ground, with a simple structure. Low, suitable for general soil layers or sandy gravel soil layers. YZJ-150Y fully automatic hydraulic drilling rig, a 4-hole down the hole vibration rotary drilling rig, is a drilling tool that combines vibration and rotary motion to drill into rock formations. The drilling tool consists of a drill bit, a vibrator, a vibration damper, and a guide cylinder. The excitation force generated by the drilling vibrator causes the entire drilling tool to perform cone pendulum motion to break up the rock formations. Compressed air reverse circulation is used to wash the well, allowing rock debris to pass through the conduit and drill pipe inside and outside the well. There is a severe shortage and imbalance of water resources, and many places are still facing serious water shortages. It has had a significant impact on daily life and production, and some major projects have solved the water shortage problem in some large cities.
