摘要
Abstract
Reviewing development history of water flooding development technology in Daqing Oilfield,the main in-novative development techniques in the past 10 years are systematically summarized,including optimized adjust-ment of well patterns in water-flooding strata series,water injection optimized adjustment of near-resistance combi-nation,and warning,prevention and control for casing damage of blocks and individual wells.Based on objective analysis of main contradiction issues of water flooding in Daqing Oilfield,development direction of core technolo-gies are determined for water flooding development in Daqing Oilfield.In terms of well pattern adjustment,research on optimized well pattern adjustment techniques is focused on"water-chemical flooding collaboration and well types optimization".Technical innovations such as well pattern optimization of"combination of secondary and tertiary oil production",infilling and profile control flooding of classified reservoirs,well-fractures collaborated pattern adjust-ment and high-efficient tapping of various well types realize transformation from uniform infilling of water-flooding vertical wells to 3D adjustment of water-chemical flooding collaboration and multiple-patterns and multiple-well types.In terms of structural adjustment,research is focused on new generation of comprehensive adjustment tech-niques of"intelligent optimization,water flooding+".Technical innovations of intelligent injection-production opti-mization,functional water flooding in low-permeability reservoirs and fracturing flooding and production enhance-ment in ultra-low permeability compartment reservoirs realize transformation from conventional injection-production adjustment to intelligent adjustment and control and multi-mode energy supplementation.In terms of casing damage prevention and control,research is focused on techniques for precise casing damage prevention and treatment with"layers warning and reproduction".Based on deepening research on geomechanical mechanisms,techniques are de-veloped for precise warning of casing damaged layers and reproduction potential tapping of casing damaged zones,achieving transformation from block and single-well warning to precise warning,prevention and control of casing damage layers by combining big data and in-situ stress analysis.关键词
