到目前为止,煤田勘探的主要手段还是采用岩心鑽探来編录岩层的地質剖面。这种方法不仅費用昂貴、进度緩慢而且有时因岩心或煤心的采取率过低,不能滿足地質上的要求。因此进一步应用和发展測井工作,把取岩芯的鑽探工作量縮减到最低限度,这是当前煤田地质勘探技术革命中的一个重要問題。
So far, the main method of coalfield exploration is to use core drilling to record the geological profile of rock strata. This method is not only expensive, slow to progress and sometimes can not meet the geological requirements due to the low rate of core or coal core adoption. Therefore, the further application and development of logging work to reduce the core drilling workload to a minimum, which is the current geological exploration of coalfield technology revolution is an important issue.
