摘要： 地层剥蚀厚度的准确恢复对建立沉积盆地原始沉积-构造演化史、热史及油气生、排、运、聚史和定量评价油气资源潜力至关重要。目前,虽有很多传统方法应用于沉积盆地地层剥蚀厚度的恢复,但这些方法都具有局限性。在充分结合白家海凸起构造演化特征的基础上,依据实际地层情况和资料条件,采取一种更新的沉积速率比值法对白家海凸起侏罗系顶部剥蚀厚度进行了恢复。研究认为,白家海凸起石树沟群剥蚀现象普遍,但总的剥蚀量较小,最大剥蚀厚度在彩16井附近,约为280m。

Abstract: Restoration of the exact thickness of eroded strata is important to rebuild the primary sedimentary and structural evolution history, the geothermal history, the history of hydrocarbon generation, expulsion, migration and accumulation, and to evaluate the potential of oil and gas resources accurately. At present, many methods have been employed in the research of the strata denudation in sedimentary basin, but each method has its own limit in application. Based on the tructural evolution research in Baijiahai arch of Junggar basin, according to the practical geological conditions and data, the method of sedimentary ratio is applied to calculate the eroded thickness of top of Cretaceous in the arch. The restoration shows that the erosion exists pervasively in Shishugou group (J2-3sh) with a relatively small intensity. The biggest thickness of erosion is near Well Block Cai-16, with the value of 280 meters.

Key words: Junggar basin, Baijiahai arch, Jurassic, eroded thickness restoration, sedimentary ratio
