洪积扇砂砾岩储集层测井精细解释研究--以克拉玛依油田为例

Fine Interpretation of Logs from the Pluvial Glutenite Reservoirs——An example from Karamay field

克拉玛依油田三区下克拉玛依亚组砂砾岩油藏储集层岩石结构复杂,非均质性强,层间差异明显,老旧测井资料解释难度较大。针对多种测井系列下复杂岩性储层参数单一模型解释精度低的难题,提出分测井系列、分岩性开展测井精细解释模型的新思路。应用解释模型对研究区846口井进行了二次解释,结果表明,分测井系列、岩性建立的解释模型具有很高的精度,该方法对提高砾岩油藏储集层测井精细解释的准确性具有重要的意义,为进一步开展地质建模和剩余油挖潜研究奠定了基础。

The glutenite reservoir of T2xk in District No.3 in Karamay field is characterized by complicated structure of rocks, strong heterogeneity,elear difference between layers and being difficuh to interpret old log data. This paper presents the new ideas about developing fine interpretation model for well logs hv different logging suites and lithologies on the basis of logs normalization. By using this model to 846 wells in studied area for second interpretation, the resuhs indicate that this model is of high interpretation accuracy and practital significance to improve, the fine interpretation precise of logs from glutenite or conglomerate reservoir.
