本文主要介绍我国先进的钻探技术在巴基斯坦煤田钻探中的应用,所取得的先进的钻探技术经济指标已达国外先进水平。文中重点论述了尖齿广谱孕镶钻头独特的破碎机理及其高效长寿的指标,其水平可与美国著名钻探公司的天然表镶钻头相比美。另介绍了优质的泥浆NV-1及LBM粘土粉的性能,在复杂煤田深孔中裸眼钻探601m,未发生任何垮、塌、缩径等现象,比美国著明的泥浆公司的产品性能优越。通过现场技术服务,使我国人造孕镶尖齿广谱钻头和优质泥浆在巴基斯坦争得市场,受到巴方的好评。
This paper mainly introduces the application of our country’s advanced drilling technology in the drilling of Pakistani coalfields. The advanced drilling technology and economy index achieved have reached the advanced level abroad. The article mainly discusses the unique crushing mechanism of sharp-tipped pregnant drill bit and its index of high efficiency and longevity, which can be compared with the natural drill bits of the famous American drilling company. In addition, the performance of high-quality mud NV-1 and LBM clay powder is introduced. The open-hole drilling of 601m in the deep hole of complex coalfields has not occurred any collapse, collapse and diameter reduction, which is superior to that of the mud company in the United States. Through on-site technical services, our artificial broach-tipped wide-spectrum drill bits and premium mud won the market in Pakistan and were well received by the Pakistani side.
