Horizontal Drilling Technique In Sulige Block’s Of Study And Applications

Sulige Block, which locates in Changqing Oil, is gas pool that is hypotonic, low porosityand low abundance,The main production formation is discovered lying at He8of Shihezi Zuand Shan1of Shanxi Zu, This paper shows horizontal drilling techniques and theories.According to the developing of horizontal drilling and technique characteristics and SuligeBlock’s geological structure, the paper analyses the applicability of horizontal drillingtechnique in this area. In accordance with the experience of real drilled horizontal wells inSulige, we analyzed and optimized drilling parameters. Then we summarized and set down aseries of drilling techniques, including well construction, BHA, the key drilling methods anddrilling mud etc.
