中文摘要:机械钻速、钻头进尺和每米钻探成本通常称之为是钻探工程的主要技术经济指标。这些技术经济指标均与选用的钻头、所用钻进规程参数和操作技术紧密相关。选用的钻头应与所钻地层的硬度、研磨性(可钻性)相适应。操作技术主要取决于司钻人员的技术、经验和水平。而钻进规程参数的选取和确定及其合理配合则是非常重要的一个因素,不可忽视。提出了临界钻进规程的概念。临界规程是一条红线,不可逾越,否则就会发生事故。正常钻进规程时,钻压和钻头转速应该合理配合,冲洗液量宜保证岩粉处于正常规程状态,以得到理想的钻探工程技术经济指标。建议根据功率表读数变化来调整钻压和钻头转速的合理配合,利用流量计监控孔底的冲洗液数量,严格控制临界规程的形成,把经验打钻和科学打钻结合起来。

Analytical Research on Rational Combination of Drilling Parameters in Diamond Drilling Engineering
Abstract:Penetration rate, bit footage and cost per meter drilling are main technical and economical indexes of exploration engineering. The indexes depend upon bit selected, drilling parameters used and operation technology. The selected bit should be suitable for hardness, abrasiveness (drillability) of rock to be penetrated. The operation technology mainly depends upon qualification and experience of driller. And selection, definition and their rational combination of the drilling parameters are an important factor, which can not be neglected. Concept about critical drilling parameters has been put. The critical parameters are a red line not to pass, otherwise accident will occur. In normal parameters drilling weight on bit and rotary speed should be rationally combined and flow rate of fluid should guarantee cuttings in the bottom of the hole in normal state in order to obtain good technical and economical results. It is suggested to adjust rational combination of weight on bit and rotary speed and control the appearance of critical drilling parameters with wattmeter seriously and quantity of the drilling fluid in the bottle of the hole with flow meter and to combine drilling with experience with drilling with science.
