Drilling mud does not fall through the process

Drilling waste mud is one of the main sources of pollution in the oil and gas industry. Due to engineering requirements, oil drilling mud is mixed with oil, water, organic clay and other materials; in the past two years, the drilling team has oil-based mud, water-based mud and composite mud. The use of this is growing, and the resulting cost increases and environmental pollution problems are getting worse.

The emergence of mud non-floor treatment system successfully solved the problem that drilling waste can not be treated efficiently and environmentally friendly. The main treatment process of mud non-dumping treatment system means that the drilling waste returned from the wellhead will be harmless while drilling. The grounding treatment can also dilute the waste mud in the waste mud pool and then classify and use it to realize the dressing of the drilling environmental protection device. The mud which has been effectively and harmlessly treated can be reused repeatedly, and the friction resistance is effectively reduced and reduced. The accident rate increases the quality of the well.

Different from the traditional way, the mud non-landing system changes the waste mud from “end treatment” to “full process control”, and the waste mud is diluted-floccated and separated into three parts: cuttings, mud cake and water. The solid matter is treated by water washing, flocculation separation and chemical reaction, so that the cuttings and mud cake reach the discharge standard, the harmful substances in the mud and the chloride ions are precipitated into the water, and then dehydrated by vacuum adsorption or extrusion to form the mud. The cake is simultaneously concentrated and treated by air flotation, filtration system and reverse osmosis system, and the treated wastewater can be reused for drilling and recycling.

Wastes such as cuttings separated from drilling waste can be reused as concrete base after a series of purification, drying and recovery; the mud water generated by cleaning the cuttings is added, stabilized, flocculated and solidified. After the liquid is separated, a mud cake is formed, which can be blended with clay or shale to burn bricks. The separated filtrate water is subjected to pretreatment processes such as destabilization, flocculation, air flotation, oxidation and adsorption filtration to remove major pollutants, which can be used for oilfield reinjection, recirculation, safe formation or discharge; after the sewage is treated by the sewage treatment system, Achieve compliance emissions.

Zhengdao Energy Mud Non-landing System is a combination of the most advanced mud purification and drying technology at home and abroad. After three years of research and development, many upgrades and upgrades, it is the only one in China that can truly realize the harmless green environmental treatment of drilling mud. Device. After the mud is not used, the solid waste from the well site will not need to be taken away for centralized treatment, which saves the space for the use of freight and treatment, and makes the environmental protection work more in place.
