摘要
基于沉积相分析的基本理论和相标志概念,遵循从点(关键井测井沉积微相分析)到线(多井对比)的基本原则,研究了测井沉积相的主要相标志。这些相标志包括由自然伽马测井、自然伽马能谱测井、自然电位测井、孔隙度测井和电阻率测井等提供的反映岩性特征和层序特征的测井相标志,由高分辨率地层倾角测井(或者井壁成像测井)提供的反映沉积结构、构造的测井相标志。对轮南油田T1Ⅱ小层进行测井沉积微相和储层参数研究的结果表明,T1Ⅱ小层主要包括河口坝、水下分流水道和前缘席状砂微相类型;储层物性参数受沉积微相制约;河口坝相区为高孔高渗带,而前缘席状砂相区为低孔低渗带。
On the basis of sedimentology and the concept of facies marks, a principle for analyzing logging sedimentary facies is discussed. The main logging facies marks include the lithologic characteristics and sequences, the sedimentary texture and structrue provided by logging information. A method for analyzing paleocurrents through logging data is also discussed. According to the principles proposed, an actual research is done in Lunnan oilfield of Tarim area. It is shown that the reservoir physical parameters such as porosity, permeability, etc. are closely related to the microfacies.
