摘要
Abstract
The accurate parameters of coal seam information and the gas content are obtained in CBM parameter well. Wire-line coring technology has been widely used in CBM well coring because of its simple structure, high drilling efficien-cy, good coring sample quality and short coring time.This paper mainly introduced the successful application of large-diam-eter wire-line coring barrel in a CBM parameter well and production well of Hebi.Based on the structure features of the se-lected coring tool and according to the thick soft coal seam conditions, the reasonable drilling parameters and technical in-surance measures were summed up with good effects.关键词
