Plugging agent for carbon dioxide gas-driven well and preparation method of plugging agent
The invention provides a plugging agent for a carbon dioxide gas-driven well and a preparation method of the plugging agent, and relates to the field of oil exploitation. The cement-based composite material comprises the following raw materials in parts by weight: 20-30 parts of oil well cement, 10-15 parts of nano calcium carbonate, 1-5 parts of modified silicon dioxide, 1-5 parts of a water reducing agent, 5-10 parts of modified montmorillonite and 1-5 parts of porous magnesium oxide particles. Uniformly mixing the nano calcium carbonate, the modified silicon dioxide, the water reducing agent, the modified montmorillonite and the porous magnesium oxide particles, adding the oil well cement, and uniformly mixing. The plugging agent is high in strength after being cured, good in sealing performance with a plugging part, and not easy to cause secondary leakage.
本发明提出了一种二氧化碳气驱井的堵漏剂及其制备方法,涉及石油开采领域。按重量份数计,包括以下原料:油井水泥20‑30份,纳米碳酸钙10‑15份,改性二氧化硅1‑5份,减水剂1‑5份,改性蒙脱土5‑10份,多孔氧化镁颗粒1‑5份。将所述纳米碳酸钙、改性二氧化硅、减水剂、改性蒙脱土和多孔氧化镁颗粒混合均匀后,再加入油井水泥,混合均匀即可。该堵漏剂固化后的强度高,与堵漏处的密封性好,不易造成二次渗漏。
