Oil and Gas drilling is the main Drilling fluids suppliers. Drilling fluids is also called drilling mud, recognized as the blood of oil drilling. But It is also content a lot of drilling waste fluid.
With the development of the oil industry, Pollution from drilling fluids suppliers is more and more serious. In oil field drilling of China,there are more than 90 cubic meters of drilling waste fluid produced each year ( excluding natural gas drilling, coal bed gas mining ). one-third of them is untreated and discharged into environment directly, cause Serious pollution. The pollution is including drilling waste fluids and waste water.
As the main drilling fluids suppliers, In the process of mining and drilling and workover, it can also produce large amounts of drilling waste mud. The mud composition is very complicated. Because there are about 18 kinds of chemical additives added into the mud in the course of drilling. The chemical additives can cause serious pollution for surrounding such as soil, surface water and ground water. For example, If there is a 4000 meter well, we need a drilling rig about weight 150 tons and total power 4,000-kilowatt and a mud pump about 3200 HP power. The mud will be produced 240 cubic meters per hour. So drilling waste management is very important.
At present, In the field of waste mud treatment, Some of the Machinery and Equipment Manufacturers such as Xi’an Brightway Energy Machinery Company. research and development a set drilling mud treatment system according to the characteristic of the mud. The mud system will greatly reduce the pollution to the environment.
