IMPROVING DRILLING TECHNOLOGY TO SERVE EXPLORATION AND DEVELOPMENT BETTER

This paper reviewed the developing achivements of drilling technology in the past 10 years,and analyzed the present situations of 10 types drilling technology,such as the optimum drilling technique, directional, cluster and horizontal well techniques, hydrocarbon reservoir protection techniques and corollary technique of deep well. The progress of drilling technology accelerated the penetration rate, improved steadily the drilling quality, reduced the drilling costs and met the requirements 0f exploration and production. It was also recom-mended the developing trend of drilling technology during the "Ninth-Five-Year-Plan",and the way 0f absorbing foreign new drilling technology of 1990s and shortening the distance between our country and other advancded countries. Finally, the paper recommended the tentative ideas of trainning and selecting scientist technician.
