摘要
杏六区中部油藏在二次加密调整后,一类表外储层和二类表外储层的动用状况得到大幅度提高。通过在分析杏六区油层沉积特征的基础上,应用该区取芯井资料,对一类油层和三类油层在不同开发阶段水洗状况进行了分析和评价,详细论述了三类油层中不同有效厚度的油层在二次加密调整后的动用状况及影响因素,针对动用程度较差的薄差储层和表外储层进行了全面动用分析。同时,结合历年来吸水剖面、产液剖面、油水井生产动态等资料对剩余油分布特点进行了综合分析判断,为即将开展的聚驱、三次加密和后续的井网调整提供可靠的依据。
On the basis of the analysis of Xing6 district reservoir sedimentary features,Appli- cation area to the core logging data,Evaluating the washed status of first and third reservoirs in various stages of development,Discusses in detail the different effective thickness of third reservoir the disposable status and influencing factors after the second encryption.Conducted a comprehensive analysis for thin and poor using reservoir and useless reservoir.At the same time,combined with the injection profile,the production profile,oil wells production perfor- mance data,giving a comprehensive analysis and judgment on the distribution of remaining oil.Providing a reliable basis for the coming polymer flooding,three times the encryption and pattern adjustment.
