| 摘 要： | 塔里木盆地地表大多为沙漠覆盖,袁层结构纵横向速度变化快,低降速层厚度一般在10-100 m之间,甚至迭150 m,激发、接收条件较差,严重影响地震资料的品质。通过炮检点整体偏移,同时采用“避高就低”的思路,将高大沙丘上的炮点和检波点偏移到低洼平坦部位,可有效改善激发、接收条件,提高地震资料品质。

| Abstract: | Most of Talimu basin is covered by desert, and its surface structure has quick change in long direction and lateral direction. The thickness of low decreasing ground is from 10m to100m, and even reaches to 150m. Bad excitation and receiving condition affect the quality of seismic data. It could effectively improve excitation and receiving condition and provides better seismic data through the measures as the shot and positioning point integrated deflection and the new thought of avoiding high and finding low, the method of moving the shot point and positioning point from high and large dune field to low land. |
