摘要
利用高精度电子压力计试井、同位素吸水剖面和氧活化注入剖面资料 ,以及油藏地质资料 ,结合油田开发动态 ,分析并解释了弱凝胶调驱对注水井渗流特性、地层污染和注入剖面的影响程度 ;指出了调驱有效与否在压降曲线上的不同反映规律 ;应用压降、压力恢复资料提供的信息 ,定量给出了胶体前缘的推进距离和推进速度的计算公式。
Using data from well test by electric pressure gauges with high precision, isotope intake profile data, oxidation activating agent injection profile data and geological information of the reservoir, combining the oilfield development performance data, the paper analyzes and interprets how the weak gel for displacement control influences water injection well flow character, formation pollution and injection profile modification. It points out that different laws presented on the pressure drawdown curve showing whether the displacement control is effective or not. Using information obtained from pressure drawdown and pressure buildup data, the paper rationally gives the advancing distance and speed calculation formulae of the colloid front.
