摘要:
 试井资料初次解释局限于常规内容，对特殊资料有必要结合地质与各项动态资料开展精细二次解释，尽可能获得更多更准确信息。YC202井K1g2层压力恢复测试资料157~164 h时段测点温度和压力异常升高，测点与地层压力恢复速度不同步，不能正确反映地层压力变化。进行精细二次解释，先对数据多次校正再解释，直至形成连续正常的双对数曲线。结合地质与动态资料综合分析认为，该井符合多层模型特征，存在压力不同的油层、水层供液。对该井实施封堵后，含水降至10%，平均增油9 t/d，堵水增油获得成功，解释结果与生产动态、地质认识较符合。通过精细二次解释，重新认识了YC202井K1g2层油藏北部油水分布规律，提高了试井资料利用率。
Abstract:
 The initial interpretation of well testing data is limited to conventional content. For special data, it is necessary to carry out fine secondary interpretation in combination with geology and various dynamic data to obtain more and more accurate information as much as possible. According to the pressure recovery test data of Well YC202 in K1g2 layer, the temperature and pressure of the measuring points increased abnormally during 157~164 h, and the pressure recovery speed of the measuring points and formation were not synchronized, which could not correctly reflect the change of formation pressure. During the secondary fine interpretation, the data shall be corrected for many times before interpretation until a continuous normal double logarithmic curve is formed. Comprehensive analysis combining the geological and dynamic data showed that the well conforms to the characteristics of multilayer model and there are oil and water layers with different pressures for liquid supplying. After plugging the well, the water cut decreased to 10% and the average oil increased by 9 t/d. It means that the water plugging and oil enhancing were successful, and the interpretation results were in good agreement with the production performance and geological understanding. Through fine secondary interpretation, the oilwater distribution law in the northern part of K1g2 layer of Well YC202 is rerecognized, and the utilization rate of well test data is improved.
