十里加汗地区盒1段为杭锦旗地区最有勘探潜力的层段。文中对盒1段25口井测试层段测录井数据进行统计分析，研究了自然电位测井曲线异常和气测全烃曲线形态与储层流体类型的关系，建立了快速识别储层流体类型的5种组合模式。对5种组合模式平面展布特征研究表明，该地区气水层分布受储层物性和烃源岩成熟度、生烃强度的双重控制，气层主要分布在研究区中南部，水层、含气水层主要分布在研究区北部。

He1 Member of Shilijiahan Zone is the most promising area for exploration in Hangjinqi Region. Through the statistical analysis of logging data for He1 Member 25 wells, this paper studies the spontaneous potential log (SP) anomaly and the relationship between total hydrocarbon curve shape and reservoir fluid type. Five kinds of combination modes to quickly identify the reservoir fluid type are established. By studying the plane distribution characteristics of five kinds of combination modes, it is considered that the distribution of gas and water layer in the area is controlled by the physical property of reservoir, maturity of source rock and hydrocarbon-generating intensity. Gas layer is mainly distributed in the central and southern study area, and the water layer and the water layer containing gas are mainly distributed in the northern study area.
