摘要
对复杂有效热储层提出了简化,提出了等效地质体的概念。建立了理想有效热储层的渗流模型,推导出地热井产能计算公式。给出了相应参数的求取方法,并对研究区的重点井进行产能计算。经过测试数据的检验分析,该热储产能的计算公式符合率可达90%,可以满足地热田热储井产能预测分析的精度要求。
A concept of effective geology body is proposed based on simplifying to the complicated the effective geothermal reservoir and the percolation model of ideal effective geothermal reservoir is founded.The calculation formula of productivity of geothermal well is deducted and some approach to obtain parameters of formula are presented.The geothermal productivity of some key well is calculated and the concordance rate is up to 90% which is verified by the testing data.This result is showed that this method can meet the precision requirement of prediction productivity of geothermal well in geothermal fields.
