库车地区致密气藏流体识别研究

通过岩心实验和理论研究表明,可以用常规测井方法来识别流体,但由于库车地区砂岩储层具有复杂的孔隙结构,并且伴有低孔低渗、微裂隙发育、非均质性强的特点,使得用常规方法识别流体准确度有所降低,因此要与其它测井方法进行综合应用才能准确识别流体。本文除了采用常规方法来识别流体之外,还初步探讨了用核磁共振测井方法来识别流体。

The Research of Tight Gas Reservoir Fluid Identification in Kuche

Core experiments and theoretical studies have shown that the conventional logging methods can be used in fluid identification. However, sandstone reservoir has complex pore structure in Kuche region, which has other characteristics： low porosity low permeability, micro fracture and strong heterogeneity, so the accuracy of fluid identification will be decreased when conventional method is used. As a result, other methods should be combined to accurately identify the fluid. In addition to the conventional method, this paper also preliminarily discusses the use of nuclear magnetic resonance （NMR） logging method to identify fluid.
