| 摘 要： | 对巴楚露头地区下切谷和礁滩地层沉积环境岩样纵、横波速测量和密度测量的结果进行统计分析,其结果表明下切谷相中峡谷相的纵横波速度以及密度均高于斜坡相,礁滩相中礁前相和礁后相的物性变化较大,礁核相的纵、横波速度以及密度相对较高。另外,在测量过程中,由于岩石的裂缝、岩石速度的各向异性、超声仪的测量精度以及密度仪对温度的灵敏度等等因素,在一定程度上会影响测量的结果。尽管如此,通过对下切谷和礁滩沉积环境的物性分析,这些结果仍然能为塔里木巴楚一间房组沉积体系的精细储层预测提供重要的线索。

| Abstract: | 50 rock samples were taken from outcrop in Bachu,Tarim,Northwestern China for study of relationship between physical properties of sedimentary rock and marine depositional system.The ultrasonic P-wave and S-wave velocity and density of rock samples,sampled in incised valley and reef depositional environment,are measured,respectively.The statistic of the measurements of the samples indicated both the P-wave velocity and S-wave velocity of valley facies are higher than of slope facies;The changes of the physi... |
