Abstract
Study on 3D Micro-pore Structure Characteristics of Dolomite Reservoir with Different Scales
Highlights
S35 interval of Tanggu oilfield, located in Dagang, Tianjin, is a tight oil reservoir, with the character of abnormal pressure, low porosity and permeability
The character of this kind of special lithologic body is poor reservoir property, small pore throat radius, the high displacement pressure, which seriously restricts fluid flow and development, so new ways and technologies should be applied in the fine reservoir description, to determine the micro pore structure of reservoir, support the oilfield development
Using the Micro - CT technology to carry on 3D scan and reconstruction for 5 cores in T12C well, combined with constant-rate mercury injection, high-pressure mercury injection and low-temperature nitrogen adsorption test technology, the paper analysis the microscopic pore structure of dolomite reservoir in Tanggu oilfield
