In 2011, southwest oil and gas field petroleum engineering system to play good western sichuan, yuan dam, unconventional "three DaHuiZhan", start the drill 75 (set), complete drilling footage total 1.1236 million meters, complete year plan 112.36%; 2 d seismic 8440 km, a 87% increase from the previous year; 3 d seismic 2456 square kilometers (square miles), complete year plan of 136%.

  In 2011, southwest sichuan gas carry out in-depth, yuan dam area, deep well drilling in shallow speed scientific research activities, to adapt to the development of low cost form supporting fast technology series and southwest technical advantage of features. At the same time, they come out of the southeast, in both domestic and overseas market realize "neat flowering, total result". In xinjiang, the northeast, the plate and the market, the high quality, safe, efficient construction won by party a; International form South America, southeast Asia, the Middle East, the three largest markets pattern, overseas drilling footage of the 87800 meters, complete year plan, 117.12% of the 2 d seismic completed 315% of the year plan, obtain good economic benefit and social benefit.
