Deep Slant Drilling and Hydraulic Pressure Test Technologies in Underground Cavity Exploration

摘要:

青岛市黄岛区拟建设海底地下油气储藏库 ,前期地质勘察工作要求施工倾角 45°、深2 2 0m的取心钻孔 4个 ,并在孔内分段进行压水试验。本文介绍了如何利用XY - 4型金刚石小口径钻机施工基岩深斜孔及压水试验技术。

Abstract:

Underground storage house for oil-gas is planned to be built in Huangdao of Qingdao city. 4 core-drilling holes with an angle of 45° and a depth of 220m are demanded to be constructed in early period of geo-engineering exploration, and water-pressure test should be carried out in several sections in each hole. How to use XY-4 type diamond slim-hole rig to drill and to do the water-pressure test has been introduced in this paper.
