Abstract This paper designed a comprehensive experiment of green drilling fluid additive preparation using discarded fruit peel, and evaluated the effects of the additives on the drilling fluid performance. This experiment integrates the basic theories, experimental techniques and the field practice of oilfield chemistry, which can improve students' professional experimental skills and abilities of analysis and problem-solving. Using discarded peels as experimental materials can improve students' awareness of environmental protection, and help to put ideas of environmental protection into oil production in the future.
