Research and Practice on Key Technology of Drilling Ultra-deep Horizontal Wells at Southeast Block in Gulf of Mexico
Wang Dou, Lin Zhu, Xiangqing Meng
It is complicated for geologic condition at Southeast Block in the Gulf of Mexico, which has a serious impact on the scientificity of drilling design and pertinence and validity of drilling technical measures. Based on it, the paper explored the application of key techniques. For example, optimum design technique of deep wells and ultra-deep wells under complicated geologic condition, and oil base drilling fluid technique with high density, high temperature resistance and anti-pollution, and prevention and treatment techniques for complicated situation and accidents under wells. Another example cementing quality techniques of complicated formation intervals and small clearance, and special drilling techniques with advanced technical facilities. The series of techniques work very well at this block by resolving the drilling difficulties in complex situations (e.g. many pressure systems, long open whole, bad stability of well wall and high temperature and pressure during drilling, and bad possibility of drilling deep stratigraphic rock.) This research would be helpful for technical development of ultra-deep extended reach horizontal well at home and abroad.
