在煤田钻探过程中,经常打丢、打薄煤层。其重要原因之一是缺乏准确的见煤预报仪表。一般只凭经验、进尺快慢、钻机振动声响等来判断钻进层位的性质。为此,在队党委的领导下,大搞群众运动,钻探、地质、测井协同作战,研觉试制出气敏见煤预报器。为保证钻探质量、安全钻进提供了新的技术。兹介绍如下。 Drilling coal in the process, often lost, thin coal seam. One of the important reasons is the lack of accurate coal forecasting instrument. Generally only by experience, footage speed, rig vibration sound to determine the nature of the drilling layer. To this end, under the leadership of the party’s party committee, they vigorously engage in mass campaigns, drilling, geology and well logging and collaborative combat operations to develop a gas-based coal predictor. In order to ensure the quality of drilling, safety drilling provides a new technology. Here is the introduction.
