Temperature-resistant and salt-resistant channeling-sealing, leakage-stopping and water-plugging plugging agent for plugging oil-water-gas well
In order to solve the problems of leakage plugging, water disaster treatment, casing damage repair, pipe channeling and interlayer channeling plugging, shot hole plugging, abandoned well filling and the like of an oil-gas well, the invention discloses a temperature-resistant salt-resistant channeling-sealing, leaking-stopping and water-plugging plugging agent for plugging an oil-water-gas well. The plugging agent is prepared by fully mixing the following components in percentage by mass: 3-6% of polypropylene fiber with the length of 3mm-5mm, 5-8% of glass fiber with the length of 1mm-2mm, 3-6% of coconut fiber with the length of 1mm-2mm, 3-5% of rubber powder with the particle size of 30-40 meshes, 8-10% of fly ash with the particle size of 600-800 meshes, 15-20% of ardealite powder with the particle size of 600-800 meshes, 5-8% of silica fume with the particle size of 2500 meshes or more and 45-55% of sulphoaluminate cement. The invention provides the temperature-resistant salt-resistant channeling-sealing, leaking-stopping and water-stopping plugging agent for plugging the oil-water-gas well, the plugging agent is formed by compounding a plurality of flexible, rigid and hydraulic cementing materials, and the plugging agent slurry has good residence property, expansibility and strong plugging and channeling-preventing capabilities, so that the plugging slurry can effectively reside in a plugged well section, and effective plugging is implemented.
为解决油气井的漏失封堵、水害治理、套损修复、管外窜和层间窜封堵、炮眼封堵、废弃井填井等问题，本发明公开一种用于油水气井封堵的耐温抗盐封窜堵漏堵水堵剂。该堵剂由长度3mm～5mm聚丙烯纤维3~6%，长度1mm～2mm玻璃纤维5~8%，长度1mm～2mm椰壳纤维3~6%，粒径30～40目橡胶粉3~5%，粒径600～800目粉煤灰8~10%，粒径600～800目磷石膏粉15~20%，粒径2500目以上微硅粉5~8%，硫铝酸盐水泥45~55%，按质量比充分混合而成。本发明提供一种用于油水气井封堵的耐温抗盐封窜堵漏堵水堵剂，由多种韧性、刚性及水硬性胶凝材料复配而成，堵剂浆体具有很好的驻留性、膨胀性以及较强的封堵和防窜能力，确保堵浆在封堵井段能有效驻留，实施有效封堵。
