Abstract: In order to make full use of the natural gas resources in Tuha oilfield and to improve the oilfield’s economic performance, a research was carried out on the plans of comprehensive utilization of the dry gas, LPG and light oil from the oilfield, in the light of the characteristics and the current status of utiliza-
tion of the resources. Material balance calculations and economic evaluations were made for each of the potential plans. According to the results it is suggested that the oilfield, with its main activities concentrating on oil and gas exploration and exploitation, can choose certain low-risk and high-profit projects to establish its local natural gas chemical industry, while satisfying
the need of natural gas consumption of Urumqi City.
