Junggar Basin Gas Exploration, Logging Evaluation Method Research And Application

Zhungaer basin is a large depositional basin where contains a large number of the oil and natural gas resource, but it is reported that there have less than 30% of the oil and gas resource have been discovered and a large number of oil and gas resource are awaiting discover and developing at present. Because of unambiguous lack of research and summarize of well logging, including the cognition of natural gas reservoir and drilling discovered technology and the methodology of reservoirs evaluation, well logging technology can not need for exploration and development of oil-gas reservoirs. For coordinated with exploration and development of oil-gas reservoirs, through deeply research and analyze which is obtained to information of geology and log and oil production test to Zhungaer basin, there have more acquaintance with gas reservoirs geologic feature in differ formation, this thesis formulate scientific and rational measure of well logging, and also develop effective methodology of interpret and evaluation gas reservoirs. This methodology has been generalized and applied to evaluate gas reservoir in Zhungaer basin. It has been obtained preferable application effect.
