摘要

海上油田未开发储量中的低品位、难采储量越来越多,受环境、经济和技术条件的限制,海上三低油田开发起步晚,尚未达到规模和有效开发的阶段。基于对海上三低油田地质油藏特征的深入分析,总结了已开发油田的主要生产特征及开发过程中面临的难点;结合海上开发条件和现状,提出了推广长水平井和多分支井技术、单井压裂和整体压裂结合、实施合理注水开发和全过程储层保护等有效的开发策略,为探索海上三低油田有效开发模式提供支持。
        There are more and more low-grade and difficult-to-extract reserves in the undeveloped reserves of offshore oilfields. Restricted by environmental, economic and technical conditions, the development of offshore three-low oilfields, low porosity, low permeability and low single reserve factor, started late and has not yet reached the stage of scale and effective development. Based on the in-depth analysis of the geological reservoir characteristics of the offshore three-low oilfields, the main production characteristics of the developed oil fields and the difficulties in the development process are summarized. Combined with the conditions and current situation of offshore development, some effective development strategies were put forward, such as popularizing the technology of long horizontal well and multi-branch well, the organic combination of single well fracturing and integral fracturing, implementing reasonable waterflood development mode and effective development strategies such as whole-process reservoir protection, so as to provide support for exploring the effective development mode of offshore three-low oilfields.
