Abstract: As one of the strategic alternatives of liquid petroleum, gas to liquid (GTL) has already wit-nessed the development and utilization of remote and
cheap gas resources. This paper evaluates the three industrialized technologies, three technologies to be industrialized and several technologies under develop-ment, and discusses their characteristics conducive to
reducing investment and operation cost. The influ-ence of gas price to production cost is also discussed.Finally, the author comes to the conclusion that the development of GTL should be not only enterprise’s but also government’s behavior.
