摘要
Abstract
High-yielding oil flow was found in Paleozoic clastic rocks in Well Sl12-2 of Tahe region in 2005. The oil flow is on the unconformity interface between Carboniferous and Silurian; hence the origin still remains discussion. Based on core, logging and seismic data, the date, tectonic and trap features of the Well Sl12-2 reservoir were concluded. 2 types of sandstone updip pinch out trap exist in Silurian in the region: a)tongue-shape ones, with monocline at the top of sandbody and pinchout line leading to the north; b)nose-shape ones, with nose-shape structure at the top of sandbody and straight pinchout line. The noseshape ones are new trap types which may have similar oil-bearing features in the region.关键词
