| 摘 要： | 有关通江—南江—巴中地区长兴组—飞仙关组沉积模式及其空间分布的研究较少,并且较为粗略。以前认为该区发育开阔台地、缓坡和盆地等沉积相沉积,但对缓坡相尚未进行详细的划分,是否存在台地边缘礁滩相带未能提出明确的认识。因此,利用新的资料,开展长兴组—飞仙关组沉积相研究对通南巴地区的油气勘探具有非常重要的意义。本文在以往研究的基础上,利用地表露头和地震资料,初步建立了通南巴地区长兴组—飞仙关组沉积模式,认为该区存在台地边缘礁滩相带,建议油气勘探部门给予重视。

| Abstract: | The Tongjiang-Nanjiang-Bazhongarea is an important exploration area of SINOPEC, with the main aim formations being the Permian Changxing Formationand the Triassic Feixianguan Formation. Because related geological data are limited, sedimentary modeland spatial distributions of these two formationsare rarely studied. It is known that sedimentary facies analysis is groundwork in the target selectionof oil-gas exploration. Various work indicated that the area was developed with open platform facies, rampfacies and basin facies. However, the rampfacies is notstudied in detail, and the reef-bank ontheedge oftheplatform is not confirmed. The papermakesuse of outcrop and seismicdata to establish a sedimentary modelof the Changxing-Feixianguan formationsin the Tongjiang-Nanjiang-Bazhongarea. As a result,a reef-bank on the edge of platform faciesis confirmedin the area,which requires special attention from the oil-gas exploration department. |
