应用数理统计方法,研究了颗粒型调剖剂在文明寨、卫城、马寨三大复杂断块油田的调剖效果;以调剖后增油降水的增值系数大小作为效果评价依据,分析发现不同开发时期的注水井吸水厚度/层数占射孔厚度/层数的百分比、地质采出程度、累计注采比、启动压力为影响调剖效果的主要因素。并且确定了文、卫、马断块油田最佳的调剖适用条件,用以指导今后调剖选井、选层、效果预测。
Applying the method of mathematical statistics to study the profile control effect of particle profile control agent in the three complex fault block oil fields of Wenmingzhai, Chengcheng and Mazhai, the value-added coefficient of oil-adding precipitation after profile control is used as the evaluation basis of the effect, The water injection thickness / number of injection wells at different development stages, the percentage of perforation thickness / number of layers, the degree of geological recovery, cumulative injection-production ratio and start-up pressure are the main factors that affect the profile control effect. And determine the Wen, Wei and Ma fault block the best profile control conditions, to guide the future profile control well, the election layer, the effect of prediction.
