摘要:At present, there is no quantitative calculation method of gel plugging agent for profile control and water plugging. Considering the influence of gel plugging agent entering the hyperosmotic channel on the effect radius of profile control and water plugging, and the influence of the dosage requirement for the actual reservoir water storage and flooding area, a new method for quantifying dosage calculation of gel plugging agent was put forward based on the dynamic production data. According to the average dosages of Q1, Q2, Q3 calculated respectively based on the displacement radius method of well testing, the water drive method of formation water storage, and the displacement radius method of advantage channels, the dosage of blocking agent Qt for profile control and the dosage of blocking agent Qd for water plugging were obtained. The method can meet the actual needs of gel dosage and relieve the layer contradictions and inner contradictions effectively, which will insure the measures of profile control and water plugging achieve the expected blocking effect.
