榆树林油田储层敏感性评价实验研究

EXPERIMENTAL STUDY EVALUATION OF RESERVOIR SENSITIVITY IN YUSHULINOIL FIELD

针对榆树林油田扶、杨油层的地质特征,根据室内实验结果,对榆树林油田进行了全面的储层敏感性评价。本文认为,榆树林油田扶、杨油层的速敏特征为中等偏弱速敏,储层流体渗流的临界速度为0.1mL/min;水敏特征为强水敏。注水开发过程中,油水流速应控制在临界速度之下。注入水的含盐量应大于或等于1750ppm。

<ABSTRACT>: Aiming at the geological characteristics of Fu, Yang reservoirs in Yushulin oil field, and according to results of laboratory test, the sensitivity of the reservoir in Yushulin oil field is evaluated comprehensively. This paper suggests that the characteristic of rate sen-sitivity of Fu, Yang reservoirs in Yushulin oil field is at the medium to weak side, the critical velocity of fluid fowing in the reservoir is 0. 1 ml/min, and the characteristic of water sensi-tivity is strong. The flowing velocity of oil and water should be controlled under the critical velocity in the process of development by water injection, and the salt content of injected wa-ter should be over or equal to 1750 ppm.
