高铁铝土矿制备石油压裂支撑剂的造粒过程研究

重点研究云南特有高铁铝土矿制备石油压裂支撑剂的造粒工艺。通过对造粒过程中水分、时间、圆盘转速和膨润土添加量各参数的有效控制,获得最佳成球率及最低破碎率的各参数指标为:水分含量控制为总量的12%,造球时间为8 h,圆盘转速为40 r/min,原料粒度d97=0.038 mm,膨润土添加量3%。此研究为高铁铝土矿制备石油压裂支撑剂提供了有力的技术支撑。

Study on pelletizing process of oil fracturing proppant preparation by monohydrallite with high iron content

The pelletizing of oil fracturing proppant was studied in this paper when monohydrallite with high iron content was used as raw materials. The best process conditions which were measured by the high pelletizing ratio and low breakage ratio were obtained by studying the water content, time,Srotary speedsSofSdisc,Sadding contents of bentonite clay and so on. It found that the best process conditions were shown as follows: water content was 12%, pelletizing time was 8h, rotary speeds of disc was 40r/min, adding contents of bentonite clay was 3%, and particles size of raw materials wasSsatisfiedSwith d97=0.038mm. This study provided technical support for the preparation of oil fracturing proppant using monohydrallite with high iron content.
