Protecting the environment ecology of drilling mud additives
Drilling fluid often contains crude oil, diesel, various oils, a large amount of chemical treatment agents. To prevent the potential impact of drilling fluid on the environment ecology, it is required to use harmless non-toxic drilling fluid.
Mud has many functions, mainly carrying rock debris the bottom of the well to the surface. With the rapid progress of oilfield technology, drilling fluids have evolved only meeting the needs of drill bits to meeting various drilling needs.
1. Clean the bottom of the well, suspend carry rock debris, keep the wellbore clean.
2. Balance formation pressure, stabilize wellbore, prevent wellbore collapse, blowout, leakage.
3. Transmit water power to help drill bits break rocks.
4. Transfer power to downhole power drilling tools,
5. Cool down the drill bit drilling tools.
6. Use drilling fluid for geological gas logging.
7. Offshore oil drilling completion engineering, including geology, exploration, cementing, casing, logging, logging, all require the cooperation of mud to complete the operation.
