| 摘 要： | 周渤然等．用ＣＴ技术确定砂岩的孔隙度．测井技术，１９９４，１８（３）：１７８～１８４本文首先提出用计算机层析（ＣＴ）技术确定砂岩孔隙度的原理和方法。通过对四块人工岩样和六十块砂岩岩样的测定，其结果表明该方法是可靠的。使用ＣＴ技术可定量、定性地解释某些岩样的内部特征，重矿物分布及裂缝变化情况。实践表明，采用图象减法技术则有助于消除光束硬化现象造成的误差。

| Abstract: | Principle and method to determine the porosity of sandstone with CT technique are briefed in this paper. The results of measuring 4 artificial samples and 60 sandstone samples show that this method is reliable. With CT technique,one can inter. pret the inner features of certain samples,distribution of heavy minerals and fracture changes qualitatively and quantitatively. It has been proved that errors caused by ray-beam hardening can be eliminated by using image subtraction method. |
