The imaging logging fracture stage research and oil control fracture distribution determination

In this paper,the imaging logging interpretation model is set to define the imaging logging response mode under different geologic phenomena,the interaction cutting relation within the cracks determines the development stage of cracks.Research shows that there are three main stages in the Proterozoic tectonic fractures in Damintun in Liaohe depression:north East fracture as the first stage of crack,northeast east as second crack,east west fractures into third crack.The findings are proved through the core test data.Based on this,comparing production capacity of different crack section,the main fractures in the study area is determined as the North east.The determination of fracture stage,occurrence and main oil control crack is of great significance for subsequent exploration and development.
