The composite curing agent is selected by indoors experiments which is composed of 7-8% cement,45-46% fly ash,35% lime,6% poly-aluminum chloride,2% aluminum sulfate and 4-5% inorganic curing agent A.It is tested for curing processing of waste drilling fluid of Well T6-2211 in Henan Oilfield.The results show that the waste drilling fluid can be effectively solidified and achieve higher compressive strength by this agent.The leaching liquid of the solidified body which is soaked in clean water for 5 days meets the secondary standard of GB8978-1996.
