聚驱井含水率特征曲线在示踪剂综合解释技术中的应用

为了解示踪剂注剂井组中未见剂井的井间参数特征，利用示踪剂综合解释技术对其进行了注采井井间储层参数综合解释；结合聚合物驱单井含水率变化特征曲线和指纹图谱相似度计算方法进行了未见剂井与见剂井的相似度计算。结果表明，注聚合物后见效井的含水率曲线下降漏斗的数目反映了优势通道的数目，见效时间的快慢在一定程度上说明最优通道渗透率的大小，见效有效期反映了地下聚驱波及的体积；综合评价结果能够初步判断未见剂井是否存在优势通道以及发育状况。利用聚驱井含水率特征曲线对见剂井与未见剂井进行相似度计算，不仅节省了示踪剂监测费用，扩展了示踪剂综合解释结果的内容，同时也为油田开发调整提供了指导和依据。

Application of Polymer Flooding Water Cut Curve in Tracer Interpretation Technology

In order to get the interwell parameter of the well which have not get tracer breaking, a similarity calculation method of fingerprint between the breaking well and the unbreaking was carried out by combinating the tracer interpretation technology with the polymer flooding water cut curve. The results showed that the number of predominance flow channel equaled to the number of peaks of the polymer flooding water cut curve. The starting response time showed that the interwell permeability and response time showed the swept volume of polymer solution. Based on the analysis of the water cut curve and the tracer testing interpretation, the interwell predominance flow channel can be predicated. The cost of tracer testing is saved and the tracer testing interpretation is expanded for this method. In addition， some suggestions were provided for the development of oil field.
