关于海上薄油层多分支水平井钻井技术研究

Study on Drilling Technology of Multi Branch Horizontal Well in Offshore Thin Reservoir

为了逐步提高海上油田的开采能力,必须及时进行海上薄油层的开发和高效利用。开采海上薄油层作业期间,一般需要借助多分支水平井钻井技术进行施工,力求降低油田开采成本,带动海上薄油层采收率、开采量的稳定提升。对海上油田薄油层多分支水平井钻井技术进行了详细分析,并对其未来发展进行了探讨,分析了多分支水平井钻井的技术要点,力求提高海上薄油层开采效率,从而满足社会发展对油田资源不断增长的需求,带动国家经济的稳定进步和长期可持续发展。

In order to gradually improve the production capacity of offshore oil fields,the development and efficient utilization of offshore thin reservoirs must be carried out in time.During the operation of exploiting offshore thin oil layer,it is generally necessary to carry out construction with the help of multi branch horizontal well drilling technology,so as to effectively reduce the oilfield production cost and drive the stable improvement of offshore thin oil layer recovery and production.In this paper,the drilling technology of multi branch horizontal well in thin oil layer of offshore oilfield is analyzed in detail,its future development is discussed,and the technical points of multi branch horizontal well drilling are analyzed,so as to better improve the production efficiency of offshore thin oil layer,so as to meet the increasing demand of social development for oilfield resources,Drive the steady progress and long-term sustainable development of the national economy.
