地震资料连片解释方法研究新疆准东煤田局部区域地质规律

新疆准东煤田面积大,聚煤环境复杂。因该区勘探时间、队伍和目的的差异,呈现出勘探区块划分零乱、勘探程度与区块测量分带精度不一的局面,致使相邻区块接壤处存在明显解释误差。为了准确掌握煤层的赋存规律,为煤炭开采提供可靠的地质依据,对准东煤田9个勘探区计2 127km2的地震资料进行了连片解释。通过对各勘探区的地震、钻探、测量等资料进行收集、整合,以及坐标转换、波型统一、时差校正等处理,消除了区块边界效应,准确地控制了研究区域内西山窑组煤系地层底板的构造形态。

Study on Coal Measure Strata Basement Structural Forms in Eastern Junggar Coalfield, Xinjiang through Seismic Data Contiguous Interpretation

The eastern Junggar coalfield in Xinjiang has a large area with complex coal-accumulating environment.As a result of different exploration operating time,teams and objectives have caused exploration block division in disorder,degree of exploration and block measurement zoning precision varying,thus neighboring blocks border area existed obvious interpretation errors.To correctly grasp the coal seam hosting pattern,provide reliable geological basis for coal mining,carried out seismic data contiguous interpretation in 9 prospecting areas total 2127km^2 in eastern Junggar coalfield.Through data collection,data integration,coordinate conversion,wave mode unification and moveout correction of seismic,drilling and surveying data have eliminated block boundary effects,correctly controlled study area Xishanyao Formation coal measure strata basement structural forms.
