Classification and working principle of water well drilling rig

The vertical reciprocation of the drill bit causes the drill bit to strike the bottom hole to break the rock formation. The structure is simple, but there is no circulating cleaning system, and the removal of chips and drilling machines cannot be carried out at the same time, so the work efficiency is low. The drilling depth is generally within 250 meters, and some can reach 500 to 600 meters. The main types are as follows. A simple percussion drill that uses the weight of the drill bit itself to impact the formation. At the lower end of the drill are some collapsible pointed flaps.

Installation steps of engineering drilling rig

The rotary table drive device of the engineering drilling rig is installed before leaving the factory. During on-site installation, it is only necessary to check whether the surfaces such as the ear plate hole of the rotary table beam, the corresponding connecting hole of the base and the connecting pin shaft are clean. When it is confirmed that there is no adverse factor, hoist the rotary table driving device into the installation position as a whole, insert the connecting pin shaft, insert the pin shaft from the outside of the wellhead to the middle of the wellhead, and lock the pin shaft with a pin respectively.

Routine Maintenance Method of Drilling Rig

Daily maintenance of compact rotary excavator drilling rigs for small drilling rigs: The lifting device using a lifting device is also called "reverse active joint" and "destructive force device". It is an important part of small drilling rig manufacturers in lifting drill pipes and tools. The structure and performance of the main hoisting wire rope and the inductor are connected together 2. a small type drilling rig, and the drill pipe at the top is on top. When the main hoisting wire rope shrinks, the rotary drill pipe and drill bit can be improved. When the power head rotates, the drill bit is drilling the ground and throwing earth. As the drill pipe force changes. After its own rotation, it eliminates the change caused by the rotation of the wire rope due to the rotation of the drill pipe.

Problems needing attention in oil cylinder assembly of workover rig

After the maintenance and assembly of the cylinder of the workover rig is completed, the pressure leakage test must be done before it can be put into use again. The cylinder of workover rig with hydraulic lock shall not be equipped with hydraulic lock during pressure leak test. During the test, the oil cylinder of the workover rig should first move back and forth several times at low pressure to discharge the air in the cylinder, and pay attention to whether the piston assembly moves with any blockage and uneven resistance. During pressure test, increase the pressure slowly and observe carefully whether there is leakage.

Steam flooding high-temperature non-killing well operation is an important stimulation technology in deep heavy oil recovery technology in oilfield, which has been highly valued by oil exploitation. As an important equipment in petroleum machinery, the working condition of workover rig is more complex. In the working process, each system will produce dynamic load, making the mechanism prone to fatigue damage. In order to ensure the safety and reliability of the system, it is necessary to carry out damage estimation and life analysis on the basis of fatigue analysis theory and finite element software. In this paper, virtual prototype simulation technology is used to establish a parametric model of the operating platform system, the pipe column pick-up system, the mechanical boom lifting system and the truss support frame.

Maintenance of drilling rig

Drilling machine is a common drilling equipment. This kind of machinery and equipment will consume a lot because of the difficult problem of working natural environment and time. Therefore, maintenance and maintenance must be carried out frequently. The benefit of doing so is that it can reduce the frequency of common failures of machinery and equipment and increase the service life of machinery and equipment.

Classification of oil drilling rigs

With the continuous development of drilling production, the use conditions of drilling rigs are becoming more and more diversified, and various types of drilling rigs have appeared accordingly. The factors that affect the type and composition of drilling rig include drilling method, drilling depth, hole size and drilling tool size, drilling area conditions (such as power or fuel, transportation, meteorological conditions), etc. The following is the classification of drilling by Wanglian Machinery.

What are the working systems of truck-mounted drilling rigs?

The work of the truck-mounted drilling rig is huge, and the working conditions and characteristics of each unit are different. According to the working characteristics of the truck-mounted drilling rig, we can divide the working system of the truck-mounted drilling rig into three parts, one is the rotating system, the lifting system and the circulation system, and the whole truck-mounted drilling rig is composed of eight major systems and equipment.

Precautions for safe operation of truck-mounted drilling rig

Before use, check the flexibility of the air motor rotation, remove obstacles within the working range of the 150m truck-mounted drilling rig and walking road, and check the passing capacity of the road. Drilling tools, propulsion mechanisms, electrical systems, pressure systems, piping and dust protection devices.
