FINE STRUCTURE INTERPRETATION OF 3-D SEISMIC EXPLORATION IN CHANGPING MINE FIELD
摘要
Abstract
The Qinshui Basin of Shanxi province,a residual coal-rich basin,is the largest coal-bed gas fields in China.The Changping Mine,located in the southern part of the Basin,is a favorable area for coal-bed gas accumulation due to structural causes.A structural map of the area is compiled by calibration of wave speed and fine interpretation of horizons,faults,collapse columns and folds on the basis of a 3-D offset data volume.Comparison suggests that the strike and the buried depth of coal measure strata of the 3-D structural description are basically consistent with the 2-D description.In addition,some small folds along the strike are observed in 3-D structural description,and 19 new faults and 24 new collapse columns are discovered.A fault in the northeastern part of the 2-D structural description and a collapse column at the northeast border are found inconsistent with the 3-D structural description.Through the performance mentioned above,a more accurate interpretation of the coal seams is proposed.The accuracy of the 3-D fine structure interpretation is further verified by logging data.and the 3-D structural description fits better the actual situation.关键词
