Research And Application Of Ultra Deep Well Drilling Technology In The Keshen Block Of The Tarim Oilfield

Tarim oilfield oil and gas energy, coming mainly from in deep formation of ultra deep well, speed ultra deep well drilling technology research and application, of our energy to succeed and west east gas transmission engineering contribution is of great significance. For ultra deep well of keshen block drilling technology research and application, effectively improve ultra deep well of keshen block exploration and development progress, provide strong support for the 21 st century China’s energy security and economic and social development and Xinjiang Daqing Construction.Keshen block of Tarim Oilfield due to deeply buried reservoir, the average drilling depth is close to or more than 7000 m, the deepest reaches 8000 m, the drilling cycle of 300 days or more, the complex geological structure, drilling extremely difficult. In view of the Tarim Oilfield Keshen block ultra deep drilling operation difficulty of formulating a plan, solve the block drilling problems, and achieved good results.According to the actual situation, the research work is mainly carried out in the following aspects:(1) application and Optimization Research of Piedmont well structure(2) the research of ultra deep well drilling technology(3) research of drilling technology application.
