随着渤海油田勘探开发的不断深入,新发现油田中边际油田占比越来越多,其储量规模小、动用难度大,同时渤海海域受生态保护、航道和锚地等因素影响较大,经济有效开发受限.基于此,从降本增效的角度出发,对常规井眼进行瘦身优化,并对其进行了经济和技术可行性分析,证明常规井眼瘦身后,具有显著的经济可行性与技术可操作性;另外,针对非标准井眼开展相应配套工具的研发,研制新型四刀翼钻头和一趟多层压裂充填防砂管柱,为瘦身井的顺利实施提供了技术保障.该研究对渤海油田非标准井眼的设计提供了技术借鉴,为边际油田的高效开发提供了理论参考.
Feasibility Analysis and Application of Borehole Slimming in Bohai Oilfield
With the deepening of exploration and development of Bohai oil fields,marginal oil fields account for more and more of the newly discovered oil fields,and their reserves are small in scale and difficult to use.At the same time,the Bohai Sea is greatly affected by ecological protection,waterway and anchorage,and the economic and effective development is limited.Based on this,from the per-spective of reducing costs and increasing efficiency,the conventional well thinning optimization is carried out,and the economic and technical feasibility analysis is carried out.It is proved that the conventional well thinning has very significant economic feasibility and technical operability.In addition,the research and development of corresponding supporting tools are carried out for non-stan-dard wells,a new four-blade drill and a multi-layer fracturing filling pipe string are developed,which provides technical support for the smooth implementation of thin well.This study provides technical reference for the design of non-standard well holes in Bohai oil-field and theoretical basis for efficient development of marginal oilfield.
