Statistical Study on Formation Natural Deviating Rule in Puguang Gas Field
Abstract:
In order to investigate the effect of stratum on well trajectory, statistical approach was used to analyze the formation natural deviating rule in Puguang gas field. The analyzed results show that the formation natural deviating rule can be divided into two groups in Puguang gas field; they are the terrestrial stratum and oceanic stratum. The formation deviation directions are different from each other in the two groups, but the deviation directions tend almost to be up-dip. The further analyzed results show that the formation deviation direction is about 270-300 degree for the terrestrial stratum, and about 180-240 degree for the oceanic stratum.
