Dian-Qian-Gui Oilfield lies in the southwest China with an exploration area of 86×104 km2 , covering Yunnan, Guizhou Provinces and Guangxi Autonomous Region. There are numerous small Tertiary basins as well as Mesozoic /Paleozoic basins with an area of 27.2 ×104 km2 available for exploration. Important breakthroughs for oil and gas exploration have been made one by one in Baise, Chishui, Chuxiong etc., illustrating the broad prospect for oil and gas development in Dian-Qian-Gui area.

By the end of 2001, four small oil and gas fields: Baise oilfield in Guangxi, Chushui gas field in Guizhou and Luliang and Baoshan gas fields in Yunnan had been discovered and taken into production. The accumulative proven OOIP is 12.69 ×104 t with a maximum annual production capacity of 14 ×104 t while the accumulative OGIP is 56.5 ×108 m3 with a maximum annual production capacity of 2 ×108 m3. Up to now, the accumulative total output is 1.109 ×106 t oil and 18.1 ×108 m3 natural gas.

In Dian-Qian-Gui oilfield, an oilfield with an oil production capacity of 14×104 t/a t was found in Baise of Guangxi and new gas fields were found through potential tapping and modification in Chishui area of Guizhou, increasing the annual gas production from 23 ×106 m3 to the top figure of 2 ×108 m3. Meanwhile, the exploration in Chuxiong basin and Shiwandashan has provided new information and data. Particularly, the important discovery of natural gas well with 1×108 m3 of gas open flow potential available in Luliang basin of Yunnan has preliminarily indicated the perspect for oil and gas development in Dian-Qian-Gui area. It is inevitable to provide a new successor as the strategic backup for oil and natural gas resources in the southern China in the new century.
