磷石膏作缓凝剂对油井水泥性能的影响
Influence of Phosphogypsum as Retarder on Performance of Oil-well Cement
摘要
Abstract
By using industrial scrap phosphogypsum instead of natural gypsum as retarder of oil-well cement, the influence of the dosage of phosphogypsum and the clinker fineness on the properties of the oil-well cement including compressive strength and sulphate resistance was studied in this paper. The results show that the compressive strength of cement block increases with the clinker fineness of the oil-well cement. When the fineness is above 400m /kg,the strength of cement is relatively high. The compressive strength of cement block increases slowly with the content of phosphogypsum. Phosphogypsum instead of natural gypsum has little effect upon the compressive strength and the sulfate resistance properties of oil-well cement.关键词
