Abstract:

According to the analysis of petroleum economy and supply demand relationship in the world, the conclusion is gained that the upstream of the industry should place considerable attention on resource, productivity, efficiency and successive rate of exploring wells. Based upon the technological areas to be concerned, the geological characteristic, reservoir characteristic and economic technological characteristic are analysed in the paper, and it is pointed out that low pressure under – balanced drilling technology must be utilised in order to complete the tasks. In addition, the present situation of development and existing problems in low pressure under-balanced drilling technology in abroad are mentioned, and the key point and direction of development in low pressure under-balanced drilling technology in china are introduced combining with some seven - year research achievement made by Southwest Petroleum Institute.

Key words: Exploration drilling, Low pressure drilling, Underbalanced drilling
