二叠系苏里格气田气藏的主要碎屑组分为直径达10 cm的卵石，沉积于鄂尔多斯盆地北部距其北向物源区(银山)150多公里处。几十年来，这些鹅卵石的运输和沉积机制一直不清楚。根据岩心检验、相分析和数学模拟(卵石应力场计算)，认为苏里格气田粗粒沉积物和卵石是在辫状河中输移沉积的：(2)苏里格气田粗粒沉积物和卵石的大小与洪水的大小一致；(3)洪水是卵石的重要输导机制；(4)“暴洪成因”辫状河-辫状河三角洲沉积模式不仅为苏里格气田二叠系粗颗粒气藏的预测提供了合理的认识，也为类似粗颗粒沉积物的天然气勘探提供了合理的认识。
Pebbles up to 10 cm in diameter, as the main clastic component of gas reservoirs in the Permian Sulige Gas Field, deposited more than 150 km away from their northward provenance (Yinshan Mountains) in the northern Ordos Basin. The transportation and depositional mechanisms of these pebbles have been unclear for decades. Based on core examinations, facies analysis, and mathematical modeling (stress field calculation of pebbles), it is thought that (1) these coarse-grained deposits were transported and deposited in braided rivers; (2) the size of coarse-grained sediments and pebbles in the Sulige Gas Field is in accordance with the size of flash flood; (3) flash flood is regarded as a crucial important transporting mechanism of pebbles; and (4) the “flash flood genesis” braided river-braided delta sedimentary model provides a reasonable understanding for prediction of coarse-grained reservoirs for gas exploration not only in the Permian Sulige Gas Field but also in similar coarse-grained sediments elsewhere.
