摘　　要：准噶尔盆地石油资源量为85.87×108t。历经50年的勘探,到目前为止石油资源探明率仅为21.85%,与我国东部勘探成熟盆地(平均60%)和世界主要含油气盆地平均石油资源探明率(77.1%)相比,石油资源探明程度总体呈较低水平,至少还应有32×108t的待探明石油地质储量。在对我国未来石油储量增长趋势、盆地资源探明程度与探明速度的关系以及准噶尔盆地“七五”—“十五”的探明储量增长规律等分析的基础上,确定出了预测准噶尔盆地储量增长的指标,并从不同角度对准噶尔盆地未来石油探明地质储量增长规律进行了预测。预测结果显示,准噶尔盆地“十一五”期间年新增探明储量将保持在(6859～9669)×104t的水平,年探明速度为0.80%～1.12%;2011—2020年,年均新增探明储量应在(6390～9690)×104t之间,年探明速度为0.74%～1.13%。根据准噶尔盆地目前的勘探情况和对石油地质条件、油气成藏特点、油气富集规律及勘探潜力的分析,认为准噶尔盆地的绝大部分待探明储量将在勘探程度较低的新区、新领域被陆续发现。The amount of oil resources of 8587million tons has been discovered in Junggar Basin .It took 50 years for oil exploration ,but the discovery rate of oil resources in the basin reaches only 21.85% up to the present. Comparing with the mature basins in easternChina (60% in average) and the major petroliferous basins in the world (77.1% in average), Junggar basin assumes a lower level in oilresource discovery rate. So an additional 3200 million tons of discovered oil geologic reserves is at least to be proven in this basin. Itpresents the analyses of growth tendency of domestic oil reserves, the relationship between the proven degree and the discovered speedof basinal resources and the incremental patterns of proven reserves in Junggar Basin in the Seventh Five-Year Plan to the Tenth Five-Year Plan period, provides the predicted indices of the oil reserves, and makes predictions of the future growth patterns of provenreserves in this basin. The result shows that the incremental proven reserves in Junggar basin will be at the level of 68.59 -96.69 milliontons during the Eleventh Five-Year Plan period, the discovered speed per year will be 0.80%~1.12%. In 2011~2020, the annual incrementalproven reserves should range from 63.90 to 96.90 million tons with annual discovered speed of 0.74%~1.13%. According to the statusand efforts for petroleum exploration nowadays, the petroleum geologic conditions and the hydrocarbon accumulation characteristics, aswell as the hydrocarbon migration/accumulation regularities and the exploration potentials in Junggar Basin, it is believed that themajority of reserves to be proven will be found in new areas or domains with low discovered rate in Junggar Basin one after another.
