炮点、检波点密度变化对成像效果的影响

A STUDY OF THE EFFECT OF THE CHANGE OF THE SHOT DENSITY AND RECEIVER DENSITY ON IMAGERY

炮点密度、检波点密度对于成本的影响是比较清楚的,而对于成像效果的影响还不是很清楚。通过研究炮点密度、检波点密度对成像效果影响,认为决定成像效果的是观测系统炮检距属性,并不是单纯的炮点密度高或者是检波点密度高。分析研究表明,在保证观测系统炮检距属性基本保持不变的情况下,适当调整观测系统炮点密度、检波点密度,既有利于施工成本的降低收又可以保证成像质量不变化。

It is obvious that the shot density and receiver density are very important to the cost,but the effect of the shot density and receiver density on imagery remains unclear.The authors studied the effect of the shot density and the receiver density on imagery,and reache d the conclusion that the property of the 3-D geometry,rather than the shot density and the receiver density,is important to imagery.It is suggested that we can adjust the shot density and the receiver density to reduce the cost under the condition that the fold and the bin are not changed.
