Research On Drainage Gas Recovery Craft Of Su48Area, Sulige

With deeply exploration and development of natural gas, the problem of watering out of gas well is becoming more and more severe. As an important stimulation technique of the mid-later period of gas field, drainage gas recovery craft is more and more highly valued. Su48area is an important block of Sulige gas field, it is significant for studying drainage gas recovery in this area, the resreach result can be used in other similar gas fields, also can be useful for subsequent resreaches and production.Through collecting and analyzing existing drilling, logging and dynamic data, contrasting widely used eight kinds of drainage gas recovery techniques, combining the geologic feature and the production condition of Sulige gas field, this paper considers that foam drainage gas recovery and successive gas lift craft are suited to Su48area. Subsequently, field application of foam drainage gas recovery is carried out, it proves that ERD-05g type of foam chemical can be used in resreached area, then injection program is compiled and the field application result is summarizing. Finally, the drainage gas recovery engineering program is worked out and foam drainage gas recovery program is optimized.This paper considers that foam drainage gas recovery craft is useful for Su48area, and the optimizing result of drainage gas recovery craft is worked out.
