查询词典 geologic

In this paper the key points discussed were that, under the condition of a sharp hypsography of desert areas of Ordos basin, we used some new geophysical methods in the investigation of surface structure to obtain high accurate surface structure data and provide reliable scientific foundation for data acquisition and process; we dealt with the optimum coupling of surface geophones and the digital realization technique in desert areas, dug into a method of high frequency compensation according to attenuations by absorption near surface, adopted data processing and correction technique, solved high frequency attenuation and geophone coupling, eliminated the influences of sharply transverse fluctuation of hypsography in desert area on the seismic data, enhanced the fidelity and SNR of seismic section, and finally picked up more geologic information on the seismic profile and improved the precision of the lateral prediction for the reservoir beds.

本文旨在研究鄂尔多斯盆地沙漠区地表变化比较大的情况下，在表层结构调查中通过应用一些地球物理新方法，以获取高精度的表层结构数据，为资料采集和数据处理提供更科学的依据；研究在沙漠区地表检波器最佳耦合的方式与数字实现技术，研究通过近地表的吸收衰减规律进行高频补偿的方法，采用数据处理校正技术，解决高频吸收及检波器耦合，消除沙漠区表层横向剧烈变化对地震资料的影响，提高地震剖面的保真度和信噪比，从而使更多的地质信息能够从地震剖面中反映出来，提高储层横向预测的精度。
