摘要
淮安盐盆石盐矿埋藏于地下深处,除利用地质钻探获取地质资料外,通常亦采用钻井测井以辅助识别地层岩性。本次选择的资料井测井曲线对区内各岩性组合均具有较好的相应特征,通过对淮安盐盆东南矿区钻井测井曲线对比分析,特别是对局部地层所对应测井曲线形态差异较大的矿段作了系统研究,同时结合区内石盐矿层品位、矿物组合特征,利用钻井测井曲线的差异性预示石盐矿局部沉积环境的变化、沉积韵律的缺失,推断研究区内在第5石盐矿层沉积时期局部发生了断层活动。
Huaian salt basin rock salt deposit is buried deep in the ground. In addition to geological data obtained by geological drilling, drilling logging is usually used to assist in identifying lithology. This study selected the data well logging curves which had good corresponding characteristics for each lithologic assemblage in the area, by mans of the comparison analysis of the well logging curves in the southeastern mining area of Huaian, focused on the ore section with large differences in logging curves corresponding to local strata , combined the characteristics of grade and mineral assemblage of the rock salt deposit, used the difference of well logging curves to predict the change of the local sedimentary environment and the loss of sedimentary rhythm ,got the conclusion that the fault activity occurred partly in the period of fifth rock salt deposits in the study area.
