地热资源综合评价方法

Comprehensive Evaluation Method of the Geothermal Resources

在对松辽盆地北部某地区地热资源储层特征进行全面分析的基础上 ,确定出井口温度和单井自然产能的计算模型 ,并分别计算了有钻井污染、无钻井污染、压裂以及电泵抽汲状态下的单井日产能。根据砂体的发育情况、物性特点、地温条件、水性条件、自然产能预测量对各资源层进行综合评价。

Based on the analysis of the reservoir characteristics of the geothermal resources in a north area of Songliao Basin, the mathematical model is determined for calculating the wellhead temperature of the geothermal water and its single well water producing capacity under various conditions, such as drilling pollution, no drilling pollution, fracturing and electric pump swabbing, etc.. At last, the sand body thickness, salinity of formation water, porosity, permeability, the geothermal temperature and the daily natural geothermal water producing capacity are considered in detail so as to evaluate the geothermal reservoirs comprehensively.
