Features: The heterogeneous sandstone oilfield exhibits significant differences in its interlayer, planar, and intra-layer geological characteristics. These differences directly impact the ultimate recovery rate and economic benefits of the oilfield. Stratified production technology can fully leverage the production capacity of various oil layers, enhance the utilization of different layers, and provide technical assurance for the sustainable development of the oilfield. This book systematically introduces the stratified production technology adopted by Daqing Oilfield at different development stages, particularly the recent advancements in stratified production technology and its practical application effects on the oilfield site. The book elaborates on the technology and application of various techniques such as stratified water injection, stratified polymer injection, stratified water shutoff, stratified fracturing, reservoir acidification, and intra-thick oil layer potential development. This book is available for technical personnel engaged in oilfield development, faculty and students of petroleum universities, and researchers for study and reference. The book mainly introduces an overview of large-scale foreign sandstone oilfield production technology, supporting technologies for stratified water injection, and chemical profile modification technology for water injection wells.
