川东北地区岩石纵波速度分布特征和影响因素的试验研究
|
摘要
岩石的矿物组分、微构造和其所处的温度围压状态是岩石声波速度的决定性因素。针对中石化川东北重点勘探区全层位的砂泥岩和碳酸盐岩地层,选取具有代表性的49种岩样,开展常温常压、常温围压和温度围压条件下的岩石声波速度测试,系统地分析中石化川东北重点勘探区全层位岩石波速的分布规律和在温度围压条件下的变化特征,得出川东北地区砂泥岩、碳酸盐岩纵波速度的均值和变化范围;采用多种数学模型研究川东北地区砂泥岩、碳酸盐岩和全层位岩石纵波速度与地层埋深、密度的相关关系,确定最优回归方程。探讨影响川东北地区砂泥岩、碳酸盐岩纵波速度的主要因素,建立温度、围压和层位与纵波速度的定性定量关系并进行初步的机制分析。综合分析表明:川东北地区砂泥岩呈现出正常沉积压实特征;碳酸盐岩的微构造复杂,微构造是决定碳酸盐岩岩声学响应特性的重要因素。
Mineral composition,microstructure,temperature and confining pressure condition of rocks are crucial factors for determining the P-wave velocity of rocks.49 kinds of rocks are chosen from the carbonate and sand-shale formations of the important exploration area in northeast region of Sichuan Province.The P-wave velocity is determined under the conditions of room temperature and no confining pressure,room temperature and confining pressure,high temperature and confining pressure.The distribution characteristics and influential factors of P-wave velocity for the rocks in northeast region of Sichuan Province are systematically analyzed.The average values and variation ranges of P-wave velocity for sand-shale formation and carbonate formation are given.Many mathematical models are used to determine the relationship of buried-depth and density with P-wave velocity for sand-shale formation,carbonate formation and whole formation respectively.The optimal regression equation is determined.The main influential factors of P-wave velocity are discussed for sand-shale formation and carbonate formation.The qualitative and quantitative relationships of temperature,confining pressure and formation with P-wave velocity are established;and the primary mechanism is discussed simply.After a comprehensive analysis,it can be realized that the deposition of sand-shale formations is continuous.The microstructure of carbonate formation is complicated and it plays an important role in acoustic response.
