海上强水体薄互层油田注水成本高，施工难度大，一直是一项巨大挑战。通过长期研究实践，提出分层精细助流注水技术，基于海上油田特点制定了目的层、水源层及先导注水井组的筛选原则。研发的分层精细助流注水管柱具有边测边调、水质监测等多种功能，具备一井多用、低成本、绿色节能、见效快的巨大优势。此项技术可减少钻井、平台设施、地面注水设施等相关成本，有效减弱水的腐蚀作用和储层伤害，对于海上类似薄互层注水油田具有广泛的借鉴和推广意义。

Water injection in offshore thin interbedded oil fields is a great challenge because of its high cost and difficulty in construction. Through long-term research and practice， separated layer self-source enclosed water injection technology is put forward to supplement energy. Based on the characteristics of offshore oil fields， the screening principles of target layer， water source layer and pilot water injection well group are formulated. We developed self-source enclosed injection pipe string and underground data monitoring system， such as measuring and adjusting， water quality monitoring， etc.， and has the huge advantages of multi-purpose in one well， low cost， green energy saving and quick effect. This technology can reduce costs related to drilling， platform facilities and surface water injection facilities， and effectively reduce water corrosion and reservoir damage. It has a wide range of reference and promotion significance in similar thin interbedded water injection oilfields offshore.
