碳酸盐岩分析仪在塔河油田地质卡层中的应用

针对塔河油田在钻进中广泛使用PDC钻头加螺杆,导致钻时变快、岩屑细小,影响岩性鉴定、地层划分及层位卡取的情况,现场充分利用碳酸盐岩分析仪采集的碳酸钙质量分数变化情况来进行岩性的鉴定,通过多口井的地质卡层,证实了碳酸盐岩分析仪在塔河油田钻井中的实用性、可靠性,提高了地层划分及层位卡取的准确性,对录井新技术的应用与发展起到很好的促进作用。

The Application of Carbonatite Analyzer in the Determination of Geological Layers of Tahe oil Field

In the light of the wide use of PDC drillbit ＋ screw in the drilling in Tahe Oil Field that makes the drilling time faster and the debris smaller and influences the lithologic identification,stratigraphic division and horizon determination,this paper makes the lithologic identification through the variation of the mass fraction of calcium carbonate collected by using carbonatite analyzer on the spot,and points out that the determination of geological layers of several oil wells verifies the practicability and reliability of carbonatite analyzer in the drilling of Tahe Oil Field,and improves the accuracy of stratigraphic division and geological layer determination,and possesses excellent promoting function for the application and development of the new logging technology.
