Long ago, drilling mud additives were commonly used to search for water sources rather than oil. In fact, they were very upset when they accidentally discovered oil because it polluted the water! Drilling is to obtain fresh water seawater, the former used for drinking, washing, irrigation; The latter is used as a raw material for salt production. It was until the early 19th century that the demand for petroleum products increased due to industrialization that drilling oil production drilling fluid gas separators gradually became popular.
The recorded drilling can be traced back to China in the third century BC. They used a technique called rope drilling, which involves first dropping a huge metal drilling tool then collecting rock fragments in a tubular container. The Chinese are relatively advanced in this technology, China is also recognized as the first country to intentionally use fluids during the drilling process.
The fluid referred to here refers to water. It can soften the rock, making it easier for drilling tools to penetrate the rock, while also helping to remove rock fragments called drill cuttings. It is very important to remove drilling debris the borehole, as only in this way can the drill continue to drill deep without any obstacles.
In 1833, a French engineer named Frauweller observed a drilling operation with a rope drill. During the operation, the drilling equipment drilled out water. At this moment, he realized that the sprayed water would be very effective in lifting drilling cuttings out of the well. The principle of using flowing liquid to remove drilling cuttings the borehole is established accordingly. He envisioned a device that would pump water along the inner side of the drill pipe into the borehole, when the water returned to the surface through the gap between the drill pipe the borehole wall, it would carry out the drilling cuttings together. This operating program is still in use today.
In 1900, during the drilling of an oil well in Deltope, Texas, drilling workers drove a herd of cows through a well filled with water. Mud forms in the water pit that is crossed by cows, which is a viscous, mud like mixture of water soil, is pumped into the borehole by drilling workers. Drilling fluid is still known as mud, but engineers no longer rely solely on water soil as raw materials for drilling fluid. They carefully mix the ingredients of the mixture to meet the specific needs under various drilling conditions. Modern drilling fluid is indeed the lifeblood of oil wells. Without them today, it would be impossible to drill deep wells.
Rotary drilling has basically replaced rope drilling. When using this technique, the drill bit is located at the end of the rotating rock pipe. The drilling process is similar to the process of using a handheld electric drill screw drill to drill into a piece of wood. Unlike drilling a few inches centimeters into wood, modern oil wells can reach depths of several thousand feet meters underground. When drilling wood, the drilling debris is carried out along the spiral groove of the borehole. This method is effective for drilling shallow holes, but suitable for drilling deep wells. When drilling deep wells, the drilling cuttings are carried to the surface along with the circulating mud. The deeper the oil well is drilled, the greater the importance of drilling fluid. It has a wide range of uses can solve various problems, these problems vary greatly place to place.
