中国石油获专利,利用测井曲线定量识别深层富锂卤水

11月6日,中国石油(601857)的发明专利《深层富锂卤水测井识别方法、系统、电子设备及存储介质》获授权,申请号为CN202410803335.0。

方案先从自然伽马和自然电位测井曲线判断岩性,再配合孔隙度曲线分析储层物性。由此建立含水饱和度模型,区分储层中不同流体的含量,然后把结果与水化学分析资料结合,用于估算地下卤水中锂离子含量。技术路线从辨认地层逐步过渡到解释流体成分,为判断富锂卤水在不同深度和位置的分布提供数据。

截至此次授权消息披露时,中国石油今年获得的各类专利授权共2255项,比上年同期增加40.24%。在2026年上半年,公司研发投入为128.87亿元,同比增长30.18%。企业知识产权记录中,中国石油天然气股份有限公司名下可查到52937条专利信息。
