稠油油藏出砂机理、影响因素及防砂技术对策——基于辽河油田稠油油藏防砂实践

以辽河油田不同类型稠油油藏的动、静态资料为基础,从多孔介质中流体渗流理论、应力分析及储层微观特征等方面入手,结合油层出砂规律,对稠油油藏出砂机理及影响出砂程度的主要因素进行了分析,提出了稠油油藏防砂技术对策。

Sand production mechanism, control factors and technical strategy of sand control in heavy-oil reservoir:based on the sand control practice in heavy-oil reservoirs of Liaohe oilfield

Based on the dynamic and static data from different heavy-oil reservoirs in Liaohe oilfield,starting from the theory of percolation flow through porous media,stress analysis and microscopic reservoir features,and in combination with a consideration of sand production regularity,the sand production mechanism and major factors to control sand production are discussed for heavy-oil reservoirs,and the technical strategy of sand control is proposed.
