准噶尔盆地石油地质条件、资源潜力及勘探方向
|
摘要
近年来,准噶尔盆地的油气勘探在许多新领域取得重大突破,展现良好勘探前景。然而,盆地第三次油气资源评价结果与勘探实际、储量增长之间的矛盾越来越突出,常规、非常规领域的石油资源潜力亟待落实。在解剖盆地石油成藏条件,分析成藏控制因素,总结不同地区、不同层系成藏模式及其富集规律的基础上,开展地质评价参数研究,优选评价方法,重新评价盆地资源潜力,梳理了盆地有利的勘探方向。评价结果显示:盆地常规、非常规石油资源量近100×10~8t,综合探明率约为27%;剩余待探明石油资源量近55×10~8 t,主要分布于富烃凹陷斜坡区的二叠系—三叠系、盆地深层及凹陷周缘低勘探程度的凸起构造。未来应围绕盆地这3个领域,加大勘探力度,同时依托技术进步,努力拓展页岩油等资源潜力大、勘探程度低的勘探领域。
In recent years, there have been a great many significant exploration breakthroughs in oil fields of the Junggar Basin.Results of the last resource evaluation for oil and gas are increasingly contradictory with the exploration practice and reserves in the basin. The potential of oil resources in conventional and unconventional fields is urgently need to be evaluated. On the basis of analysis of the oil reservoir-forming conditions and its controlling factors, summarization of the oil accumulation patterns and enrichment rules of different areas and strata, this paper optimizes evaluation parameters and methods, then re-evaluates the oil resource potential and points out the favorable exploration direction of Junggar Basin. The evaluation results show that the amounts of conventional and unconventional oil resources in the basin are approximately 100×10~8 t, the comprehensive proven rate is about 27%. The amounts of remaining resources to be proved are nearly 55×10~8 t, mainly are distributed in the PermianTriassic system in the slope area of hydrocarbon-rich sag, the deep part of the basin and the uplift structures with low exploration degree around the sag. In the future, we should focus on this three fields of the basin, strive to expand the exploration areas of shale oil and other resources with high potential and low exploration degree.
