塔东低凸起震旦系断陷台地沉积特征及发育模式
Sedimentary Characteristics and Evolution Models of the Sinian Rift Platform in the Low-Uplift,Eastern Tarim Basin
摘要
Abstract
By utilization of drilling cores and seismic data,this work revealed the sedimentary characteristics of Sinian in the low-uplift,eastern Tarim basn and established its evolutionary model.The study suggested that three sedimentary facies were identified in the Sinian dolostones,including tidal fiat,grain beach and ramp types.Well correlation and seismic sections showed that Sinian sedimentary sequences in this area have a wedge-shaped reflective structure,indicating a northward dipping rift basin and overall pattern of high in south and low in north.An evolutionary model of the basin was constructed that shows a change from a northward gentle dipping monocline at the early stage into a rift platform,of which the primary portion is the slope from the well TD-1 to the north of well DT-1.关键词
