Southwest Oil and Gas Field Branch Shunan Gas Mine Hejiang gas production area for low-pressure small-scale well gas wells, well production technology and more wells, intermittent production wells and a high degree of mining, production and storage of low production status, focusing on strengthening the new technology Digestion and absorption of new technologies and on-site promotion and application. In January 2004, the operation area was officially opened in Shuangliu 2 6 gas wells fly ball pump ball lift, after more than six months of practical experience has shown that the production of Well 2 6 from the previous production week to shut the well, change to continuous production More than a month, the monthly gas production is 3.8 times the original, as of the end of June, the well oil production of 100.3 million cubic meters year on year increase. The practical application of this new technology provides precious experience for gas field recovery in old gas fields.
