中国石油获专利，在实验装置里重现煤层气排采

11月6日，中国石油（601857）的发明专利《一种用于模拟煤层气排采的实验装置及方法》获授权，申请号为CN202410312127.0。

装置把煤层模拟、排水计量、气量控制与流量记录串在一条实验线上。研究人员可给模拟煤层施加压力，记录排出多少水，再调节进入控气单元的压力，使采气量保持在设定水平。监测单元同时记录气体流量的变化。这样，在为某一储层选择排采制度前，可以先在实验室比较产水和产气数据，观察恒定产量条件下的排采过程。

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。
