BEIJING, Jan 8 (Reuters) - Top Chinese oil and gas producer PetroChina pushed its domestic crude oil output above 110 million tonnes in 2012 for the first time in 17 years, while also achieving its fastest annual output growth in more than a decade.

PetroChina and other state oil majors have been striving to boost their output and reserves to reduce China's dependence on oil imports, which rose to 56 percent of the country's overall requirement in 2011. China, the world's second largest oil consuming country behind the United States, became a net importer in 1993.

PetroChina's domestic crude production hit 110.33 million tonnes (2.2 million barrels per day) last year, up 2.6 percent from the previous year, parent company China National Petroleum Corp (CNPC) said on its website (www.cnpc.com.cn) on Tuesday.

That was the fastest year-on-year growth since PetroChina listed overseas in 2000.

PetroChina also managed to keep oil production in China's flagship Daqing oilfield in the northeastern Heilongjiang province stable at 40 million tonnes, or 800,000 bpd, CNPC said. That marks a decade of keeping Daqing output above 40 million tonnes a year, following a previous 27 years of the field's production topping 50 million tonnes.

Oil and gas production in the northwestern Changqing field rose above 45 million tonnes of oil equivalent in 2012, with oil production of 22.6 million tonnes, CNPC said.

Three oilfields in the northwestern Xinjiang region -- Xinjiang, Tarim and Tuha -- produced a total of 18.39 million tonnes last year.

PetroChina added more than 600 million tonnes of proven geological oil reserves and more than 400 billion cubic metres (bcm) of geological natural gas reserves last year.

Separately, top Asian refiner Sinopec said on Tuesday that its proven oil and gas reserves rose to more than 800 million tonnes of oil equivalent in 2012.

China has said it will be able to sustain its current domestic crude oil production of around 4 million bpd until at least 2030 due to recent hydrocarbon resource finds.
