河南焦作煤田程村井田岩、煤层对比方法

Contrast methods of rock and coal seams at Chengcun well field in Jiaozuo,Henan

岩、煤层对比是煤田地质勘探工程中的重要工作之一。综合运用岩性段旋回法、测井曲线法、层间距法、标志层法、煤层特征法等对程村井田岩、煤层进行了对比,探讨了针对不同层段采用不同方法组合能取得较好效果,对指导豫北地区岩、煤层对比具有借鉴和指导作用。

Chengcun well field, lies to the northeast of Jiaozuo, Henan Province, is an important coal base in Huixian City. The contrast of rock and coal seams is one of the key works in coal geological exploration. By a comprehensive use of cyclic method in lithizone, well logging, bed space, indicator horizon and coal seam characteristic method, the author made a contrast on the rock and coal seams in Chengcun well field, discussed the effect of different methods adapted to different coal seams, and their use for reference and guidance in the fields of rock and coal seams contrast in the north region of Henan Province.
