Plugging agent, preparation method and construction method
The invention relates to the technical field of well drilling, in particular to a plugging agent, a preparation method and a construction method. The plugging agent is prepared from the following raw materials: G-grade cement, a thixotropic agent, a retarder, an expanding agent, a weighting agent, bentonite slurry, a composite plugging agent (coarse), composite plugging slurry (fine), fibers, intelligent gel, modified rubber, flaky mica, quartz sand and clear water. The concrete is prepared from the following raw materials in parts by mass: 100 parts of G-grade cement, 1-5 parts of thixotropic agent, 1-2 parts of retarder, 2-5 parts of expanding agent, 10-15 parts of weighting agent, 20-30 parts of bentonite slurry, 5-10 parts of composite plugging agent (coarse), 15-20 parts of composite plugging slurry (fine), 2-5 parts of fiber, 1-2 parts of intelligent gel, 3-5 parts of modified rubber, 2-3 parts of flaky mica, 5-10 parts of quartz sand and 200 parts of clear water. The plugging agent provided by the invention has a remarkable effect on solving the problems of return-loss leakage, re-leakage and the like, and the drilling time efficiency is improved.
本发明涉及钻井技术领域，特别是涉及一种堵漏剂、制备方法和施工方法。一种堵漏剂，由以下原料制备而成：G级水泥、触变剂、缓凝剂、膨胀剂、加重剂、膨润土浆、复合堵漏剂(粗)、复合堵漏浆(细)、纤维、智能凝胶、改性橡胶、片状云母、石英砂和清水；各原料的质量配比关系为：100份G级水泥、1‑5份触变剂、1‑2份缓凝剂、2‑5份膨胀剂、10‑15份加重剂、20‑30份膨润土浆、5‑10份复合堵漏剂(粗)、15‑20份复合堵漏浆(细)、2‑5份纤维、1‑2份智能凝胶、3‑5份改性橡胶、2‑3份片状云母、5‑10份石英砂以及清水200份。本发明提供一种堵漏剂，该堵漏剂在解决失返性漏失、复漏等方面有显著的效果，提高了钻井时效。
