GELLING AGENT FOR INSULATION OF WATER INFLUX IN WELL |
| 摘要 |
FIELD: oil and gas industry.SUBSTANCE: agent comprises the components in the following ratio of wt %: reagent RIKOR - 3.0-4.0; LAPROXID DEG-1 - 1.5-2.0; water - the rest. Preparation of the agent consists in previous dissolving of the reagent RIKOR in the estimated amount of water. Then, in the resultant solution LAPROXID DEG-1 is dissolved to obtain a homogeneous composition.EFFECT: increased efficiency of insulation of water influx in the well due to improving the heat resistance of the resulting gel in time during its interaction with low-mineralised formation water and increasing the duration of insulation.10 ex, 1 tbl |
