Demonstration Application of 3500m Core Drilling Rig in Oil and Gas Well Exploration

Abstract:

3500m core drilling equipment (YDX—6 drilling rig) is independently developed in China for deep mineral resources exploration, by which, the drilling depth can reach 3500m with N standard drilling scheme, and the important feature is the use of long cylinder drilling and tripping. This paper mainly introduces YDX—6 drilling rig about its production test in oil and gas well exploration, and elaborates the mining area structure, borehole structure, drilling process, drilling effect, major problems encountered and the solutions.
