| 摘 要： | 本文用准噶尔盆地东部油区58口井共2257块油气储层岩芯标本,在常温常压和模拟地下温度压力下对V_P/V_S及衰减系数进行了精确测量,结合密度、孔隙度及岩石学研究获得个同岩性地层含油、水、气不同流体的V_P/V_S比、泊松比及不同深度的速度校正曲线;用回归分析获得V_P-V_S,密度-速度,密度-孔隙度的相关关系式;用数学统计获得稠油地区岩芯砂岩的速度特征值;用AVO技术进行模型计算和实例验证.为油气碳氢检测,测井速度标定,声阻抗及演,模型正演等提供了有价值的数据.

| Abstract: | P, S-wave velocity, and attenuation coefficent of 2 257 core samples that selected from the reservior beds of 58 boreholes in east oil area of Zhungeri basin were accurately tested un-der the ambient pressure and temperature or model pressure and temperature. Combined with density, porosity, petrology study, chemical analysis of rocks, we obtained the velocity ratio of P to S-wave, Poisson's ratio, and velocity correction curves of the dry rock, and the rock saturated with water and oil; the correlation equations of Vp-Vs density-velocity, density-porosity were obtained by using regression analysis; the velocity characteristic value of sandstone samples was obtained by using statistics method; the AVO technique was cited for modelling and the results was verified by acutal data. It provided suefull data for hydrocarbon testing, well logging velocity calibration, sonic impedance inversion, and modelling and is significant for guiding oil-gas exploration of this area. |
