摘要
从地震资料解释的地质要求出发，将信噪比、分辨率和保真度三者紧密地联系在一起，指出了以往常规地震采集质量定性评价的不足，提出了对复杂地区野外地震采集质量的具体量化参数与多因素模糊综合评判方法。地震理论模型和实际资料计算结果表明：该评价系统适于复杂地表条件下地震采集方法的选择，为保证施工质量、降低采集成本，提供了科学的依据，具有很强的实用性和广阔的推广应用前景。
According to the demand of seismic geological interpretation, it is very important to relate the seismic signal-noise ratio and resolution with fidelity in seismic exploration. Because of the shortcoming of qualitative evaluation in old time, the article describes a new method to quantize the field seismic parameters and to evaluate the result by the means of fuzzy evaluation. With the result of theoretical calculation and field data testing, this method has the advantage in field parameter choosing, cost reducing, quality assuring and best determination under complicated conditions. As a result, the technology is very useful and has a wide future.
