In recent years, although domestic onshore oil and gas regions have devoted great efforts to management of waste generated in well drilling and well completion, the techniques still remain too inefficient to dispose waste thoroughly. Nowadays, domestic and foreign?drilling waste management?solutions differ greatly in technological solutions, supporting equipment and environmental investments. Most domestic oilfields have been directly solidifying the waste in sewage pits after well drilling and well completion.
At present, there are many?drilling waste management methods and devices with different treatment effects. View from the drilling situations of various drilling site at home and abroad, the most important and commonly used drilling waste management devices are vertical centrifuge and?hi-g dryer.
Vertical Cuttings Dryer?is key equipment for drilling cuttings treatment. During drilling process, the customer may use water based mud for former stage operation, and oil base mud may be coming later for deep drilling operation. Some customer may buy two sets on line drilling cuttings treatment?for water based mud and oil based mud separately. Some user want to reduce budget and only prepare one set on line drilling cuttings treatment for water based mud and oil based mud drilling cuttings.
Drilling waste management aims to recover the solid phase which is generated during the drilling process, for the purpose of finally meeting environment protection and discharge standards. In such a way, it can achieve zero discharge of drilling mud, prevent environmental pollution and reduce the drilling costs.
