The strategy, principle and pattern of gas development are controlled by reserve, gas properties and gas reservoir type. According to those, this paper carries on a detailed research and put forward corresponding measures. The conventional gas reserve is limited in China. So, we should work for enlarging gas reserve and strengthening effective exploration and development of unconventional gas. On the other hand, the gas import should be taken into consideration. Only if insisting on integrated development  work, and applying relevant technologies in terms of the development properties of different gas reservoir types, we can just inc rease profit and decrease costing.
