为提高勘查程度,在经过野外现场踏勘、仔细分析该区内的地震地质条件和现有地质资料的基础上,充分研究分析了普查地震工作中存在的问题,按照《煤炭煤层气地震勘查规范》标准进行了二维地震勘查设计与数据采集工作。本区共计完成二维测线7条,同时对本次所获得的时间剖面进行了评级,并经资料解释,了解了覆盖层厚度及变化情况,查明了二1煤层的构造形态及分布范围。
In order to improve the degree of prospecting, based on the site survey in the field and the careful analysis of the seismic geological conditions and the existing geological data in this area, the problems existing in the census and seismic work are fully studied and analyzed. According to the “Coalbed Methane Seismic Survey Specifications” Standard 2D seismic survey design and data collection. In this area, a total of seven 2D survey lines have been completed. At the same time, the time profiles obtained in the current study have been rated. After the data interpretation, the thickness and variation of the overburden have been found. The structure and distribution of the second coal seam have been identified .
