煤田地球物理测井中塌孔对煤层解释的影响分析

在煤田地质勘探的过程中常常会因为钻探技术和泥浆材料问题,导致钻孔井壁出现残缺,产生塌孔现象,给煤层解释准确性造成一定的影响。为了能够更好的分析这个问题,文章对地球物理测井技术进行了相应的阐述,以及塌孔对煤田测井各参数曲线造成的影响,并采取相应的措施来解决问题。

In the process of coalfield geological exploration, drilling technology- and mud material problems often lead to drilling hole wall incomplete, resulting in hole collapse phenomenon, which has a certain impact on the accuracy of coal seam interpretation. In order to better analyze this problem, this paper expounds the geophysical logging technology-, and the impact of borehole collapse on the parameters of coal logging curve, and takes the corresponding measures to solve the problen.
