水分析技术在古潜山探井的应用

The application of water analysis technique in Buried Hill exploration well

水分析技术是古潜山钻探实施欠平衡录井的一项配套技术,应用现场水分析中所测定的主要离子含量变化规律,来判断地层的油水、气水界面,通过古潜山12口井水分析资料的研究应用,在判断油水界面方面取得了很好的效果,这种技术在现场随钻过程中能快速、准确地判断出油水、气水界面。

Water analysis technique is a matching technique used during Buried Hill underbalance pressure logging,which applys change regularity of key ion content measured in field water analysis to diagnose formation′s oil water and gas-water interface.Through researching and applying analysis data based on Buried Hill 12 wells,it provides very good results in diagnosing oil water interface.This technique can quick and accurately diagnose the oil-water and gas-water interface during field drilling.
