摘　　要：测井是储层流体性质识别的重要方法。玛湖凹陷三叠系百口泉组是特低孔低渗的砂砾岩储层,对于该类非常规储层流体性质识别,采用常规的测井资料解释方法无法满足要求。因此通过对玛湖凹陷三叠系百口泉组的储层流体性质研究,结合储层特征以及实际井组的测井和试油资料,利用异常侵入特征定性识别法和多因素流体识别法,能够较为准确的识别储层流体性质。研究结果表明,对M131井区内的11口探井统计分析,有7口井为油层,4口井为水层,利用异常侵入特征定性识别法,流体识别符合率在90%以上;采用多因素流体识别法现场测井解释符合率由原来的40%提高到86%以上,为低渗储层流体定性识别提供了新的方法。Logging is an important method to identify reservoir fluid properties. Triassic Baikou formation in Mahu depression is low porosity and low permeability sandstone reservoir. For the identification of fluid properties of unconventional reservoirs, conventional logging data interpretation can＇t meet the requirements. In this paper, reservoir fluid properties in the block were studied. Combined with the reservoir characteristics and well logging and oil testing data, the reservoir fluid properties were accurately identified by the method of qualitative identification and multi-factor fluid identification. The results showed that, among 11 wells in M131 well area, there were 7 oil wells and 4 water wells; by using the abnormal intrusion feature qualitative identification method, fluid identification coincidence rate was more than 90%; The coincidence rate of field log interpretation was increased from 40% to over 86% by using multi-factor fluid identification method, which could provide a new method for qualitative fluid property identification of low permeability reservoirs.
