On Lithology Identification Methods of Glutinite in Southeast Ramp Region of Lishu Fault Depression
摘要
Abstract
It is difficult to identify lithology of glutinite in reservoir logging evaluation. Crossplot method and lithology-sensitive index curve method are applied to indentify glutinite lithology in southeast ramp region of Lishu fault depression. Constructed is lithology-sensitive index curve (Its) with acoustic time difference, natural gamma and deep detection resistivity curves. The Ils curve can reflect the granularity of rock change: Ils of the glutinite is greater than 1; 7ls of sand is between 0. 3 and 1; Ils of mudstone is less than 0. 3. The rock content model can quantitatively compute contents of mudstone, sand stone and glutinite. The calculation results accord with the lithology given by logging, and can identify typical glutinite, sand and shale. Therefore, it provides foundation for glutinite reservoir log evaluation.关键词
