摘要
油藏开发中出砂问题是影响产能的重要因素,了解油藏出砂机理对有效控制出砂以及选择合理的防砂方法具有重要意义.综合国内外文献及大量实例认为,地质因素和油田开发工程因素是影响油层出砂的2大因素.进一步分析油层出砂的力学机理,将油层出砂的力学机理分为剪切破坏和拉伸破坏两类.研究成果对进一步研究油层出砂机理及改善防砂工艺措施具有重要的意义.
Sand production is an important factor affecting productivity of reservoir exploitation. Understanding the mechanism of sand production is meaningful to sand control effectively and choose the rational methods. Through summarizing many examples and literature both home and abroad, the two factors of sand production are geo-factor and engineering factor, further more, in the view of mechanics, the factors can be included shear damage and tension damage. This research has important meaning to further studies on sand production mechanics and improving the craft measure of sand prevention.
