Equipment and method for preparing high-temperature low-density well cementing material
The invention discloses high-temperature low-density well cementation material preparation equipment and method, and relates to the technical field of well cementation material preparation, and the method specifically comprises the following steps: S1, mixing high-early-strength oil well cement raw materials; s2, grinding and screening the high-early-strength oil well cement raw materials; s3, heating and calcining the high-early-strength oil well cement raw material; s4, preparing the high-early-strength oil well cement; s5, preparing a high-temperature low-density well cementing material; according to the preparation equipment and method of the high-temperature low-density well cementation material, the coal gangue is added into the cement raw material, and the coal gangue has a certain calorific value, the coal consumption is reduced, the coal gangue is stable in component and small in silica-alumina ratio fluctuation, so that the C3A content of clinker can be further increased, the C3A hydration is relatively fast, and the development of the early strength of the well cementation material is facilitated; and the multiple stirring tanks share the same driving source, material stirring is achieved, through the sweeping mechanisms in the stirring tanks, the materials drifting away and adhering to the inner walls in the stirring process are swept downwards, the preparation weight of the well cementation materials is more accurate, and cleanliness of the interiors of the stirring tanks is guaranteed.
本发明公开了高温低密度固井材料制备设备及方法，本发明涉及固井材料制备技术领域，具体包括以下步骤：S1、高早强油井水泥原料混合；S2、高早强油井水泥原料粉磨筛选；S3、高早强油井水泥生料加热煅烧；S4、高早强油井水泥制备；S5、高温低密度固井材料制备；该高温低密度固井材料制备设备及方法，通过此水泥原料中添加煤矸石，因其本身具有一定的发热量，减少煤用量，煤矸石成分稳定，硅铝比波动小，能进一步提升熟料C3A含量，C3A水化较快，有助于固井材料早期强度的发挥，且多个搅拌罐使用同一个驱动源，实现物料搅拌，且通过搅拌罐内部的清扫机构，将搅拌过程中飘散粘连在内壁的物料向下清扫，固井材料制备重量更加精确，保障搅拌罐内部的整洁。
