The history of barite development you don't know
In the vicinity of volcanoes, there is often a powder-gray barite, which is not conspicuous, non-magnetic, non-toxic, does not react with most substances, and does not dissolve at all in water. Its specific gravity is very large, reaching about 4.3, so it is often used as a weighting agent for drilling mud.
In 1949, New China was founded, and everything was waiting for prosperity. In order to completely get rid of the humiliating modern history of China, China urgently needs to realize industrialization and change from an agricultural country to an industrial country. Oil is the blood of industry, and nature is particularly important. Fortunately, the Daqing Oilfield was discovered on the Songnen Plain in 1959. The oil workers rolled up their sleeves and worked hard, striving to extract the underground black treasures as soon as possible to help the industrialization of New China. Among them, the most famous oil workers is the "iron man" Wang Jinxi.
In March 1960, Wang Jinxi led a team to Daqing Oilfield. When the second well was drilled, a blowout occurred. At that time, there was no barite powder and cement could only be used instead. However, the effect of cement was limited after all and needed mixing. Under the conditions at that time, where there was a mixer, Wang Jinxi took the lead in jumping into the mud pool to stir with his body. Other workers also jumped into the pool one by one. After some hard work, he finally subdued the blowout.
The specific gravity of mud and clay is low, only 2.5. In the process of oil exploitation, sometimes their weight can not be balanced with the underground oil and gas pressure, which is easy to cause blowout accidents. In this case, adding barite powder to the mud can increase the mud weight, which is a good way to avoid blowout.
barite powder for oil field exploitation
According to the prediction of the oil department, by the end of the 20th century, 1.4 to 1.5 million tons of barite powder would be needed every year for onshore oil drilling.
There is another magic in this humble barite. Some barite with better crystal structure will glow in the dark after being exposed to the sun, sometimes even for several years. This phosphorescent effect was first discovered by Cassiolaos in Bologna, Italy in 1602, so barite is also called "Bologna stone". (Polarite)
Natural barite and water zincite symbiosis, blue phosphorescence from barite.
In 1774, Scheler obtained a white powder by heating barite, which is similar to the properties of bitter earth (magnesium oxide) and lime (calcium oxide). Later this white powder was called heavy earth and was included in the first element table by Lavoisier.
In the end, Humphrey David, who used the same method as the discovery of magnesium, calcium and strontium, heated heavy soil to melt, then used mercury as a cathode, and electrolyzed amalgam of new elements. By heating and steaming off the mercury, the impure new element is obtained. He named the new element after the Greek heavy "barys": Barium, which translates to "barium" in Chinese ".
Like magnesium, calcium and strontium, barium is also an alkaline earth metal, but its chemical properties are more active than magnesium, calcium and strontium. It can be ignited, emitting a green flame and producing barium peroxide. This characteristic flame color reaction of barium also allows it to be used to make beautiful fireworks.

Nowadays, the demand for barite ore in various industries in China has been increasing, and the application prospect of heavy stone is more extensive.
