Drilling process
Introduction
Drilling is a key process employed in oil and gas exploration and production. It is a complex procedure that involves several specialized techniques to successfully drill an oil or gas well. The drilling process can be divided into three main phases: surface drilling, intermediate dri......
rock breaking
Rock is one of the most versatile materials on the planet. From large boulders to sand, each grain has its own unique composition and properties that make it suitable for a variety of applications. But often, rocks are simply pulverized for use as an aggregate in construction projects and for othe......
Tank type hot stuffy metallurgical steel slag treatment technology
Introduction
Steel slag is a by-product of iron and steel production. It is a solid waste generated by the steel industry, including iron and steel-making, sintering, and coking. Steel slag contains components such as calcium, iron, silicon, aluminum, sulfur, manganese, and trace elements. The co......
Production Technology of High Strength Phenolic Resin for Foundry Coated Sand
Production Technology of High Strength Phenolic Resin Casting Coating Sand
High strength Phenolic Resin Casting Coating Sand has been widely used in precision casting. Because of its high strength and high temperature resistance, it is more suitable for the production and manufacturing of parts w......
Well Guanji is being cemented
The mechanical casing process, or “cementing” is an important step in the oil and gas drilling process that involves running steel or fiberglass casing into the drilled hole. The purpose of this process is to provide stability to the well, to help prevent the sides of the hole from collapsing as......
Steelmaking slag
Steel Slag Introduction
Steel slag is a byproduct of the steel-making process, providing a valuable resource and throughout the 20th century has been used in a variety of applications. Those applications range from construction materials, fertilizer and soil conditioner to abrasive and filtration......
Mechanism of Liming
The Mechanism of Lime Slag-making
Lime slag-making is a process which involves the chemical decomposition of lime with the help of silicon. In this process, limestone or chalk-containing compounds are heated to very high temperatures, usually around 1000 degrees Celsius. The resulting reaction is......
