真假油气显示识别方法在准噶尔盆地中部勘探中的应用

The application of the method of distinguishing true and false oil and gas shows in Zhunger Basin.

为了优化钻井液体系,提高钻速,或者考虑到处理工程事故的需要等,需在钻井液中加入带有荧光材料的添加剂,这给现场准确发现油气显示增加了困难。针对上述问题,采用地化、定量荧光录井技术进行真假油气显示的识别,十分必要。该文通过D1井的应用实例,用实验及对比分析的方式介绍了这一方法,展示了应用这种技术在准噶尔盆地中部勘探施工中的实用价值。

In order to optimize drilling fluid system, raise ROP or consid er the needs of processing engineering accidents, we need to add additives with fluorescence materials in drilling fluid, and this increases the difficulty for accurately finding oil and gas shows on spot. According to the problems said abo ve, it is necessary to use geo-chemical and quantitative fluorescence logging te chnology to carry out true or false oil and gas shows distinction. Taking the ex ample of Well D1, the author introduced the method by the way of experiments, co rrelation and analysis, and showed the real value of the technology during the e xploration and the construction in the middle part of Zhunger Basin.
