摘  要:
川东北YB气田长兴组-飞仙关组井段岩性横向变化大且储层非均质性强。根据不同流体在测井响应上的差别,采用孔隙度-含水饱和度交会图法、正态分布法(P1/2法)、电阻率测井识别法等方法综合识别气水层。实际应用表明,其识别结果与实际生产情况基本一致,说明上述方法是可行的。

摘  要:
In YB Gas Field,Changxing-Feixianguan formations have strong heterogeneity and lithologic properties vary greatly.Based on the comprehensive analysis of reservoir characateristics and "four-property" relationship(Lithology,Physical Character,Resistivity and Oil-Bearing),along with core analysis and logging information,parameter interpretation models are built to reflect reservoir characteristics and gas-content variation.These models can be used to study the fluid property and evalution methodology.According to fluid difference on logging response,gas and water formation crossplot approach by porsity-saturation crossplot,normal distribution and resistivity log methods are synthetically identificated.Through practical application,fluid properties of Well YB 27 and Well YB9 are effectively identified.These results are basically consistent with that of the practical production.
