On June 13, the ministry of land and resources at a press, published 2015 national oil and gas resources dynamic evaluation results. Evaluation results show that: my country is rich in oil and gas resources, unconventional oil and gas resource potential is considerable, surge in natural gas resources in the key areas, despite the difficulty of exploration and development to gradually increase, but have a good future steady increase oil to gas.

According to introducing, at present our country is rich in oil and gas resources. Petroleum geology resources 125.7 billion tons, 30.1 billion tons of recoverable resource, compared with the 2007 national oil and gas resources evaluation results, petroleum geological and recoverable resources increased by 64% and 64% respectively. Gas geological resource of 90.3 trillion cubic meters and 50.1 trillion cubic meters of recoverable resources, compared with the 2007 national oil and gas resources evaluation results, natural gas geology and recoverable resources increased by 158% and 158% respectively. Resource is the main reason for the surge was an increase in exploration workload and deepening the cognition on geological exploration areas, technological progress lowered the threshold of the resources.

Unconventional oil and gas resource potential is considerable. The embedded depth of 4500 meters to shallow shale gas geological resource of 122 trillion cubic meters, 22 trillion cubic meters of recoverable resources, advantageous area has realistic to the development of a value of 5.5 trillion cubic meters of recoverable resources. Embedded depth of 2000 meters for shallow coal-bed gas geological resource of 30 trillion cubic meters of recoverable resource of 12.5 trillion cubic meters, has the reality can be advantageous area of development value of 4 trillion cubic meters of recoverable resources.

Happily, the surge in natural gas resources in the key areas. Sichuan basin natural gas geological resource of 20.7 trillion cubic meters, recoverable resource of 11.2 trillion cubic meters, compared with the evaluation in 2007, up 2.8 times and 2.3 times respectively. Offshore basin gas geological resource of 20.8 trillion cubic meters, recoverable resource of 12.2 trillion cubic meters, compared with the evaluation in 2007, increased by 157% and 157% respectively. In addition, ordos, tarim basin, such as natural gas, also has a large amount of growth.

Next, our country will focus on large basin waters of the new series of strata and new area and looking for high quality reserves, forming "eastern western sustainable and fast development, sea big breakthrough" pattern of oil and gas exploration and development.

Oil and gas exploration and development difficulty increases gradually. First of all, the remaining resources quality, the lower the overall 80% of oil and gas resources as low quality, high risk types, CBM and shale gas was still in the stage of local breakthrough, comprehensive exploration. Second, the object complexity of exploration and development, enhance the concealment of the resources, find it harder to, increase the construction difficulty, for the requirement of increasing the technology equipment level, ecological civilization construction is also put forward higher requirements of oil and gas exploration and development. Even so, the future stability of oil gas there is still a basis.
