Abstract

To overcome the shorting of inorganic gelatinous such as cement in plugging jobs, MFC-GM plugging agent is developed. MFC-GM is composed of 20% network building material, 70% gelatinous material, 9% activators, and 1% technologic behavior regulator and is used in aqueous slurries with water to cement ratio 1:1.4-1.8. The results of laboratory performance properties evaluation show that the depth of MFC-GM slurries squeezed into sandpack is far less, and the plugging strength of MFC-GM is, about 25MPa, far higher than G grade oilwell cement. This phenomenon is explained in terms of the functions of ingredients and the structure. MFC-GM can be used for plugging perforations and water producing zones, processing following characteristics: plugging radius is less than 0.8m and adjustable; initial setting time in rang 2-6 hours adjustably. MFC-GM plugging agent can meet the needs of unconsolidated sand gas reservoirs and improve plugging effect of gas well water-flooded layer and leakage zone.

Key findings

  • MFC-GM is composed of 20% network building material, 70% gelatinous material, 9% activators, and 1% technologic behavior regulator and is used in aqueous slurries with water to cement ratio 1:1.
