水文地质特征评价及水文条件与产能关系研究

Study on hydrogeological features evaluation and relationship between hydrological conditions and capacity

通过对地下储层开发试验井组的水离子组成、水力压头的展布特征等水文参数分析,研究了水文条件与产能的关系。水文地质特征分析表明:随着矿化度的整体增高,单井产能明显增大;储层压力水头越高,产能越高。研究成果进一步验证了储层的保存条件是决定产能的主要因素,为实现高效开发提供了地质依据。

This paper reviews the relationship between the hydrological conditions and productivity by investigating the hydrological parameters such as ion composition and distribution of hydraulic pressure head.The analysis of the hydrogeological features shows that:with the degree of mineralization increasing,the capacity of single well rises;and the higher the reservoir pressure head is,the higher the capacity is.The research results prove that the storage condition of the reservoir is the main factor to impact the capacity,which provides the geological basis for high efficient development.
