查询词典 impedance

The Xujiahe formation in south Sichuan basin is featured by continental clastic sedimentary, thin sand mud interbed, and the welldeveloped sandstone in this area, however, its lithology is tight and its physical properties is poor. In the case of gas bearing, the acoustic velocity difference between the sandstone and the shale is too little to make clear responses on seismic data, as a result, it is very difficult to conduct the gasbearing prediction and to analyze the gasbearing range distribution by means of conventional impedance inversion and hydrocarbon detection.

四川盆地蜀南地区上三叠统须家河组为一套砂泥岩互层的陆相碎屑岩沉积，砂岩发育，但岩性致密，物性较差，砂岩储层含气后的速度与页岩速度相差不大，在地震剖面上无明显的响应，因而采用常规波阻抗反演和含气检测技术不能有效解决该类含气储层识别问题和含气范围展布问题。
