摘要
针对我国近海油田多为疏松砂岩稠油油藏的情况,在常规防砂和出砂冷采的基础上,提出适度出砂开采。论述海上油田适度出砂开采技术的原理及增产机理,以及适合适度出砂开采方式的油藏条件与生产阶段。分析海上油田适度出砂技术关键点"度"的确定依据,给出4种不同平台产出砂处理模式的允许含砂量,讨论海上油田适度出砂技术实施过程中应该注意和解决的关键问题。
This paper proposes the reasonable sand producing process for China＇s offshore unconsolidated sandstone heavy oil reservoir,based on conventional sand control and cold flow production process.It discusses the technical principles and mechanism of production for the reasonable sand producing process,as well as reservoir conditions and production stage suitable for this process.It summarizes and analyzes the determined base of the key technical point ＂degree＂ for the reasonable sand producing process.Besides,this paper shows the amount of sand allowed for the four different processing mode of platforms output sand.Finally,this paper discusses comprehensively several critical issues that should be paid more attention to and be resolved in advance in application of this process.
