全直径岩心孔渗测定仪的研制

Development of Full Diameter Core Porosity and Permeability Testing Instrument

针对常规物性分析中经常遇到的易碎地层钻取小柱塞岩样困难以及非均质性等特点,设计了全直径岩心孔隙度渗透率测定仪。详细介绍了颗粒体积、孔隙体积的测量原理以及径向渗透率的测试原理,并分析了仪器设计过程中几个重要参数的选取。通过实际应用,证明该仪器操作简便,测试准确,在油田中具有推广意义。

It is difficult to coring small sample in the fragile reservoir and the heterogeneity is also hard to avoid. The new type of full diameter core automatic porosity and permeability testing instrument is intended for this situation. This paper focuses on introducing testing principle of pore volume, skeleton bulk and permeability. It also lists several important parameters selection of the instrument. It is proved easy to operating and the result is reliable through practical application. It is worth promotion in sites.
