摘　　要：相对主力油层而言,非主力层因其含油面积小、厚度薄、叠合程度低等客观原因,在历次井网调整中都不是重点调整对象。但随着老油田进入特高含水开发后期,开发对象由主力层逐渐向非主力层转移,非主力层的地位和作用日益凸显出来。以双河油田非主力层为研究对象,在分类评价的基础上,提出对不同类型的非主力层采取不同的开发对策。实践表明:只要对非主力层地质特征认识到位、措施针对性强,也能取得较好的开发效果。Compared with main producing series of strata,non-essential series of strata,with the characteristics of small oil - bearing area,thin thickness,low degree of superposition and etc,can not be taken as the key targets in well pattern adjustment in early stage of oilfield development.However, when the old oilfield entered the late development stage with ultra-high water cut,the role and significance of non- essential series of strata become increasingly prominent and therefore,the development focus is shifted.Taking non-essential series of strata as the main research object,this paper puts forward different development strategies for different types of non-essential series of strata based on classification and evaluation.The practical experience indicates good development effects can be achieved if there is a better understanding of geological characteristics and proper measures taken on the other hand,which provides guidance for other reservoirs of the similar kind.
