A good deep well is an important part of well cleaning. The same groundwater production, well washing and non washing are * different. The water quality of deep wells is close to that of the sea, and the well water is mainly saltwater. In general, engineering dewatering well equipment can be used for drilling shallow water wells, but when faced with the need to drill water wells hundreds of meters or more, it is necessary to use air compressors. Generally speaking, small drilling rigs are primarily used for developing groundwater resources, including daily water use, agricultural water use, and industrial water use. It is also applied in hydrogeological exploration, construction engineering, bridge foundation drilling, and other fields. In large-scale oilfield engineering, professional drilling equipment is used.

The breakthrough and innovation of ultra deep well cementing technology in different geological environments, efficient sealing of lost formations, and high hydrogen sulfide content in ultra deep well drilling matching technology. Finding a water source is very important during drilling. Due to the assumption that you cannot find a good water source, you will spend a lot of time and energy drilling. The important homework we do is drilling efficiency. Assuming you have time to drill, it will add to our drilling costs. Therefore, in order to save our costs, it is necessary for us to learn how to find water sources and then carry out drilling operations.

So how can we find a water source? Firstly, it is important to understand and master the rules and characteristics of terrain, water systems, and groundwater distribution to prevent abandoned wells with limited water resources. Groundwater generally exists in aquifers and can be divided into porous aquifer slack rocks, karst aquifer carbonate rocks, weathered aquifer bedrock, and fractured aquifer bedrock according to rock properties. Groundwater can be extracted from these four rocks. Secondly, the amount of water in the well is generally selected based on the storage capacity of the aquifer, which is determined by the rock properties and thickness of the aquifer. Fully tested the technical level and operational experience of drilling engineers. Drilling a well is a huge project. There are many preventive measures before, during, and after drilling. In the process of drilling, it is necessary to pay attention to details, otherwise many problems will arise during the drilling process, directly affecting the progress and effectiveness of the drilling.

Check whether the oil level in each fuel tank meets the requirements, whether the gear oil level meets the requirements, whether the oil quality is normal, whether there is oil leakage, whether the main and auxiliary wire ropes are cracked, and whether the connection is intact and safe. The drilling company will tell you to check whether the elevator is rolling smoothly, whether the internal butter is contaminated, and whether the steel structure has cracks, corrosion, welding and other damages. Drill bits play an important role in drilling, but the quality of the drill bit directly affects the power and quality of drilling. Therefore, when selecting, attention should be paid to the selection and use of drill bits. When operating a drilling rig, it is necessary to pay attention to several aspects in order to achieve better production and operation.

Under the action of atmospheric pressure, the circulating fluid flows from the sedimentation tank through the annular gap of the return ditch to the bottom of the well. The drilling company tells you that the rotary table drives the drill rod and drives the drill bit to drill holes. The negative pressure generated by the mud pump sucks in the debris mud drill rod and then rises to the water. After passing through the sedimentation tank of the mud pump, the circulating fluid continues to flow into the wellbore, and the circulation starts again and again, forming a reverse circulation. Circular drilling.
