outhwest oil company ShuNa gas Wells, 59 in July 2008 with the implementation of gas lift small diameter tube with pressurized composite technique, since the bubble note is outstanding. By June 16,, this tone has accumulative total production Wells 28.048 million cubic meters of natural gas.

Well, the bubble DuoCi was 59 row of gas lift, and the process technology, DianQianBeng yield, but the effect is not ideal. ShuNa gas on the basis of summarizing the experience, began in July 2008 with the implementation of gas lift bubble row and a little diameter tube note bubble composite technology. Small diameter tube note bubble process is small diameter tube from gas well will be down to the bottom of the tubing direct injection, increase the gas bubble with water effect, make the gas well can normal production. In the process of operation, through repeated use small diameter tube note bubble process measures, gas well production has achieved good effect. This fully reflected small diameter tube note bubble in the compound technology process in an important role.

After 22 days after uninterrupted drainage, and the well on July 23, 2008 began to see gas, highest nissan volume reached 70000 cubic meters of water, nissan 160 cubic meters. At present, the well still normal production and the average gas production is 12000 cubic meters, gas well production remaining fully tapping.
