DISCUSSION ON ACADEMIC ISSUE, CURRENT TECHNOLOGY AND DEVELOPMENT TREND OF OIL AND GAS DRILLING

On the effective exploration and development and sustainable utility of underground resources, this paper presents the important role and position of drilling, and points out the way for the future drilling. The key academic and technological issues such as mechanics, chemistry, engineering geology and know-how etc., are discussed detailed in the paper. Some important systemic and new drilling technologies are elaborated, including horizontal well, large displacement well, deep well, superdeep well, coiled tubing, slim hole drilling, underbalance drilling, advanced MWD and visible drilling etc. Based on the sufficient data, the paper presents current drilling technologies both at home and abroad, and indicates the future development of drilling and the key problems to be resolved.
