Application of cement system for deep well with high temperature to xuwen X1 well

In order to effectively improve quality of well cementation,selected new high temperature fluid loss control agent TW110L as cement for xuwen X1 well,its adequate to 90-150 ℃ wells.Tested compatibility of TW110L and retarder TW302L with water,cement and silica flour in field,shows that TW110L’s performance well at high temperature and it also has those characteristics,such as easy to adjust density time,short transit time,high compressive resistance and etc.and it has obtain success in xuwen X1 well’s cement.It solve the problem of high temperature well’s cement.
