固体矿产大倾角深孔有缆随钻定向钻进技术应用与示范

Application and Demonstration of Directional Drilling Technology with Cable while Drilling in Large Inclination Deep Hole of Solid Mineral

为减少钻探进尺,在固体矿产大倾角地层的勘查设计中,往往将勘查孔设计为定向钻孔,而现有的钻探工艺较难满足地质设计的目的,为解决矿床大倾角深孔钻探定向造孔技术,我单位成立了课题组研究固体矿产大倾角深孔绳索取芯有缆随钻定向钻进技术的应用与推广。通过应用研究与实践,较好的解决了我单位所承担项目的难题,有效的节约了钻探进尺,较好的达到了地质目的,高效的完成了勘查任务,并将应用技术推广应用到了其他项目。

In order to reduce drilling footage,in the exploration and design of high dip strata of solid minerals,the exploration hole is often designed as directional drilling,but the existing drilling technology is difficult to meet the purpose of geological design.In order to solve the directional drilling technology of high dip deep hole drilling in deposits,our unit set up a research group to study the directional drilling technology of high dip deep hole coring with cable while drilling in solid minerals.Application and promotion.Through the application research and practice,the difficult problems of the project undertaken by our unit are better solved,the drilling footage is effectively saved,the geological purpose is better achieved,the exploration task is efficiently completed,and the application technology is extended to other projects.
