水平定向钻进技术在青海钾盐矿开采中的应用研究
Application of horizontal directional drilling technology in the exploitation of a potash mine,Qinghai Province
摘要
Abstract
In order to improve the mining efficiency and output of a potash mine in Qinghai province,the mining scheme of through wells is put forward,after water injection from horizontal wells,brine is extracted from vertical wells,which greatly increases the production of potassium salts.The sticking accident occurred in the initial stage of construction,which was perfectly avoided by optimizing mud formula,reasonable selection of bit and design of anti-sticking drilling tool.After the completion of 40 horizontal and vertical wells,the annual output of potash in this area has increased by 35000 tons,which proves that the scheme of using horizontal directional drilling technology to improve the efficiency and output of potash mining is feasible!The related research results can provide theoretical basis and practical guidance for the subsequent use of horizontal directional drilling technology for soluble mineral exploitation.关键词
