Seepage characteristics of water-flooding operations after deep profile control and oil displacement：A case study of Menggulin sandstone reservoir
摘要
Abstract
Deep profile control an d oil displacement are key techniques deployed to enhance development performances of sandstone reservoirs. With changes in formation pore structures upon completion of profile control, together with consequential water-flooding seepage patterns and different chemical flooding techniques, it may become even harder to clearly understand distribution of residual oil. Under such circumstances, test data in deep profile control and oil displacement in Menggulin sandstone reservoir of Huabei Oilfield after deep profile control and oil displacement operations were used in combination with log-log derivative curve and pressure semi-log curve for data interpretation. In addition, production performances were analyzed to highlight seepage characteristics corresponding with relevant plots. Sandstone reservoir deep profile control and oil displacement. Seepage patterns in consequential water-flooding operations can be categorized into 5 types, i.e. infinite flow, finite flow, double media, gel plug boundary and homogeneous formation.With regard to seepage characteristics of infinite flow and finite flow types, well patterns can be modified to proceed with deep profile control operations. As for the concave features in pressure derivative curves of double media type, suitable flooding operations in different layers can be performed upon completion of profile-control operations. As for gel plug boundary and homogeneous formation types, formation energy conditions in low-pressure oil producers can be enhanced through removal of gel plugs in these wells.关键词
