What is rig drilling？Drilling is the use of mechanical equipment to strata drilled into the cylindrical hole with a certain depth of engineering. According to the rock crushing method and the tool type, it can be divided into a drill and a rotary drill.
In the geological work,using of drilling equipment to drill into a smaller diameter, the depth of the larger cylindrical hole, also known as the drill.The diameter and depth of the drilling depends on the use of the rig drilling and the depth of the mineral.Drilling for oil, natural gas, and ground water are both large in diameter. The main functions are as follows:1. Obtaining the underground material, which is the core, the core, the cutting, the liquid sample, the gas sample and so on. As a geophysical logging channel, obtain the rock mineral various geophysical field data. As an observation of the dynamic condition of the groundwater layer under the artificial channel. As the combination of exploration and mining, exploitation of groundwater, oil gas and geothermal drilling.2 as the geophysical logging channel, obtain the rock mineral various geophysical field data. 3 as the observation of the dynamic condition of the groundwater layer under the artificial channel. 4 used as the exploration and exploitation of underground water, oil and gas, geothermal and other rig drilling.
Rig drilling can be divided into geological reconnaissance and exploration drilling, hydrological and geological drilling, wells or drilling engineering geology, geothermal drilling, oil drilling, coal drilling and field drilling, construction land drilling by use of drilling.
Rig drilling is a systematic project, which is a combination of many kinds of equipment, tools and materials. At the same time, it is a multi program closely connected, continuous operation of multi link chain. The whole process of construction is quite complex.
The completion of each well includes three stages: pre drilling, drilling and completion. Each project stage and a series of construction processes. The main procedures generally include: location of well, road survey and foundation construction, installation derrick, moving, installation of equipment, a open drilling, secondary drilling, drilling, drilling, change a bit, drilling, completion, electrical measurement, casing, cementing operation etc..
