我国主要盆地油气资源勘探开发现状和发展前景

Hydrocarbon Exploration,Production Status and Prospects in China's Major Petroliferous Basins

截至2007年底,全国累计探明原油地质储量中的72%、经济可采储量中的87.4%以及累计探明气层气地质储量中的37.4%、经济可采储量中的42.3%已投入开发。全国原油剩余经济可采储量205809.83×104t。有15个盆地累计探明原油地质储量超过1×108t,它们的合计剩余经济可采储量为203968.00×104t,平均储采比11.67,而地质资源量和可采资源量分别占全国总量的82.0%和84.8%,平均探明程度分别为43.5%和42.1%;待发现常规石油地质资源量和可采资源量分别占全国总量的72.3%和76.6%。全国气层气剩余经济可采储量24372.60×108m3,在12个累计探明气层气地质储量超过300×108m3的盆地中,剩余经济可采储量24326.11×108m3,平均储采比40.3;地质资源量和可采资源量分别占全国总量的87.7%和88.7%,平均探明程度分别为19.0%和18.2%;待发现常规天然气地质资源量和可采资源量分别占全国总量的85.3%和86.5%。我国油气储产量集中于大中型盆地,而且也是待发现资源主要阵地。

By the end of 2007,72.0% of tive recoverable oil reserves,37.4% of the and 42.3% of the cumulative recoverable million tons of remaining recoverable oil the cumulative proven oil reserves in place, 84.4% of the cumulacumulative proven gas（excluding dissolved gas） reserves in place, gas reserves had been developed in China.China has 2058.0983 reserves,and there are 15 major oil basins,each with more than 100 million tons of cumulative proven oil reserves in place.For these oil basins,their remaining recoverable oil reserves are 2039.68 million tons in total,their average R/P ratio is 11.67 years,and their oil resources in place and recoverable oil resources account for 82.0% and 84.8% of the totals in China respectively.The exploration maturities for oil resources in place and for recoverable oil resources are 43.5% and 42.1% respectively,and their undiscovered oil resources in place and undiscovered recoverable oil resources account for 72.3% and 76.6% of the totals in China respectively.Furthermore,China has 2437.26 billion cubic meters of remaining recoverable gas （excluding dissolved gas） reserves,and there are 12 major gas basins,each with more than 30 billion cubic meters of cumulative gas reserves in place.For these gas basins,the total remaining recoverable gas reserves are 2432.611 billion cubic meters,their average R/P ratio is 40.3 years,and their gas resources in place and recoverable gas resources account for 87.7% and 88.7% of the totals in China respectively.The exploration maturities of gas resources in place and recoverable gas resources are 19.0% and 18.2% respectively,and their undiscovered gas resources in place and undiscovered recoverable gas resources account for 85.3% and 86.5% of the totals in China respectively.Therefore,most conventional hydrocarbon reserves and production in China are concentrated in these major petroliferous basins,and they are also the main exploration targets for undiscovered hydrocarbon resources.
