通过分析以往停聚区块对采聚浓度、综合含水的界限制定比较单一的状况,对2007年停聚的区块,在含水、采聚浓度、聚用量等参数上都放宽了界限,在深入分析中区东部及东区停聚后开发效果及不同类型停聚井组各项参数变化规律的基础上,提出了主力油层井组合理停聚时机及技术经济界限。通过对中区东部及东区不同类型停聚井组日产液、综合含水、采聚浓度、提高采收率、聚用量变化规律的深入分析,总结了主力油层含水回升后期井组停聚原则及方法,为今后停聚区块提供了依据。
Through the analysis of the past block aggregation on the concentration of the concentration of water, integrated water boundaries to develop a relatively simple situation, the block in 2007, the convergence of water, the concentration of aggregation, aggregation and other parameters on the relaxation of the boundaries in depth Based on the analysis of the effect of development after the stopping of the east and the east of the Central Region and the variation of various parameters of the various types of stopover wells, the reasonable timing and technical economic limit of the well group in the main reservoir are proposed. Based on the in-depth analysis of the variation of daily production, integrated water, concentration of collected oil, enhanced oil recovery and poly-accumulation in different types of stopover wells in the eastern and eastern part of Central China, the principle and method of stopping oil well in late well after oil- , Provide the basis for the future park block.
