摘要
在储层低孔渗、低压、岩性及物性非均质性等因素影响下,苏里格气田盒8段和山1段高、低电阻率气层、气水层并存,且气水在纵向剖面和横向上分布不均,给测井气水层识别带来很大困难,通过分析苏里格气田气层识别难点,总结了近年气层识别的方法,评价了这些方法的优劣,并提出了一些新的气水层识别方法,将进一步提高苏里格气田气层识别准确率,对于苏里格气田勘探开发有着重要的意义。
Affected by low permeability, low porosity, low pressure, lithology, and heterogeneity, both Shan 2 and He 8 members in Sulige gasfield have some features of coexistence of gas and gas-water layers with high and low resistivity, and uneven gas-water distribution in horizontal and vertical directions, further leading to great difficulty to identify gas-water layer. In this study,some difficulties were analyzed, some methods to identify gas layer were summarized, their advantage and disadvantage were evaluated, and many new methods to identify water and gas layers were presented. These may increase identification accuracy and have significance for exploration and development of Sulige gasfield.
