The Present State and Developmental Suggestion of Drilling Key Techniques

On the basis of literature review, the latest developing trend of world drilling technologies was discussed. The research development of the major project in the National 863 Project of China, Advanced Drilling Technologies and Equipment, and the present situation of domestic key drilling technologies during the 11th Five-Year Plan period were introduced. Then the key technological gaps between china and foreign countries were analyzed and compared. In view of the present drilling difficulties and technical requirements in domestic oil and gas exploration and development, the future trend of drilling technologies and the key ones that should be more concerned were proposed. This article offers a reference for the establishment of future drilling technology development planning.
