制定油田油水层测井解释标准的方法研究

The study of making the logging standard to identify oil and water layers in oilfield

以柴达木盆地西部油田为例,在储层"四性"关系研究及测井曲线标准化的基础上,结合岩心、录井、生产动静态等地质资料,利用交会图法、储层产能级别法和主成分分析法等方法,制定油水层测井解释标准,分析其异同及优劣。通过对比分析得出:单一的方法虽有其先进性,但也存在明显的不足和局限性,综合多种方法制定测井解释标准能更为客观和准确地识别油水层。综合方法经实际验证,应用效果较好,为新油田开发的早期介入以及实现经济、有效地开发提供了新思路。

Taking the Western oilfield in Qaidam basin as an example. Based on the study of 4-property and standardization of logging curves, combined with core, logging, dynamic and static geological data production, the oil and water well logging interpretation standard is drawn up by using the crossplot method, reservoir productivity level method, the principal component analysis method and analyse the differ- ence and advantage of these methods. The comparative analysis shows that a single method has its advan- tages, but there are also shortcomings and obvious limitations. Formulation of many methods which make standards of logging interpretation will objectively and accurately identify oil and water layers. Practice shows that it has good effect. This provides new ideas to enter early in development of the new oilfield and realize economic and effective development.
