摘要
安岳气田是西南油气田公司重点勘探开发区块,其储层类型为裂缝-孔隙型。由于安岳气田须二段孔隙度较低,储层非均质性较强,利用线性的孔隙度计算方法算出的孔隙度与岩心孔隙度相比偏低。通过研究,认为利用雷蒙汉特声波非线性公式计算的孔隙度与岩心孔隙度吻合较好。
Anyue gasfield is an important exploration and development block for PetroChina Southwest Oil and Gasfield Company in Sichuan Basin. And its reservoir type is fractured-porous one. Especially, there is lower porosity and stronger heterogeneity in Xujiahe 2 Member (T3x2). So, the porosity calculated by linear method is lower than that from core analysis. After study, it is considered that the porosity calculated by nonlinear formula Raimon Ramymer-Hunter acoustic wave is well coincident to that from core analysis.
