- Abstract
A large number of core test data were used to classify the sandy debris flow reservoir and investigate its development patterns by combining with seismic data and previous researches. Based on the combination between single-well evaluation and integral evaluation, the sandy debris flow reservoir in the Paleogene Favorable Structures of Nanpu Sag were comprehensively evaluated through reservoir classification method. Result indicates that the reservoir mck mainly consists of lithic feldspar sandstone and feldspathic lithic sandstone, which are characterized by medium composition maturity and low-medium structure maturity. The reservoir with relatively low quality is mostly low-porosity and low-permeability reservoir with relatively strong interlayer and lateral heterogeneities. The Dong- 3 Member of No.2 Structure and upper Sha- I Sub-member of No.3 Structure indicate favorable reservoir qualities, which are mainly classified as Category-I and Category-11 reservoirs. The lower Sha-I Sub-member in the No.3 Structure show a poor reservoir quality. This research could provide certain guidance for the prediction of favorable hydrocarbon zones and the well deployment.
