Abstract

Abstract:

Based on the synthetical analysis of observation of thin section, scan electrical scope, cathode analysis, X-diffraction, etc., there exist five kinds of diagenetic events and three kinds of diagenetic facies in the deep reservoir of Dongying depression. Combined with the analysis of Ro, palaeogeotherm and so on, the deep reservoir has been in the late diagenetic stage. According to the structural characteristic of Dongying depression, the diagenestic models of different structural belts have been built, there are still favourable secondary pore developed zones in the deep reservoir of different structural belts.

Key words: deep reservoir, diagenesis, diagenetic model, secondary pore, Dongying depression
