The oilfield began to be explored in 1961. During the past 50 years, 23 oil and gas production zones have been discovered, according to Hou, a deputy to the National People's Congress (NPC) which is convening its annual session.

By the end of 2010, proven reserves of oil and natural gas reached 1.42 billion tonnes and 82.6 billion cubic meters respectively.

The oilfield produced 7.5 million tonnes of oil and gas in 2010, ranking the seventh largest among China's oilfields.

There are still great potentials of oil and gas reserves for the oilfield, Hou said.
