Well drilling plugging agent with good weather resistance and preparation method thereof
The invention belongs to the technical field of well drilling auxiliaries, and discloses a well drilling plugging agent with good weather resistance and a preparation method of the well drilling plugging agent. Comprising the following raw materials in parts by weight: asphalt particles, urea resin, rosin particles, calcium carbonate particles, high alumina cement, semi-hydrated gypsum, castor oil, white mineral oil, 2-5 parts of ammonium polyphosphate, modified gelled stone, calcium metasilicate, magnetized barium hexaferrite and anhydrous oxalic acid. Comprising the following raw materials: asphalt particles, urea resin, rosin particles, calcium carbonate particles, high alumina cement, semi-hydrated gypsum, castor oil, white mineral oil, ammonium polyphosphate, modified gelled stone, calcium metasilicate, magnetized barium hexaferrite and anhydrous oxalic acid. According to the well drilling plugging agent with the good weather resistance and the preparation method thereof, formation pores and cracks at the well wall can be plugged for a long time when well drilling is suspended, the stable state of the well wall can be kept for a long time, the state storage time is long, and the weather resistance is high.
本发明属于钻井助剂技术领域,公开了一种耐候性好的钻井用封堵剂及其制备方法,包括以下原料:以重量份为单位,包括以下原料:沥青颗粒、脲醛树脂、松香颗粒、碳酸钙颗粒、高矾土水泥、半水石膏、蓖麻油、白矿油、聚磷酸铵2份至5份、改性胶岭石、偏硅酸钙、磁化六铁酸钡、无水草酸,以重量份为单位,包括以下原料:沥青颗粒、脲醛树脂、松香颗粒、碳酸钙颗粒、高矾土水泥、半水石膏、蓖麻油、白矿油、聚磷酸铵、改性胶岭石、偏硅酸钙、磁化六铁酸钡、无水草酸。该耐候性好的钻井用封堵剂及其制备方法,可在暂停钻井时对井壁处地层孔隙和裂缝的长时间封堵,能够长时间的保持井壁的稳定状态,保存状态的时间较长,耐候性较强。
