摘要:
南海北部潮汕坳陷侏罗系具有很大的油气勘探潜力，沉积特征对其储层的发育具有明显的控制作用。通过对研究区最新地震资料精细解释，可以划分出4个典型地震反射界面和3个地震反射层，根据层序界面圈出侏罗系分布特征和残留厚度；通过地震相-沉积相转换对比分析研究，识别出侏罗纪地层不同时期的沉积相类型及其分布特征，重塑了潮汕坳陷侏罗系沉积演化史。该区主要发育5类沉积相、8种沉积亚相，其中滨岸三角洲前缘亚相和深水扇中亚相分别控制了碎屑流砂岩优质储层的发育；此外，浊流砂岩储层主要受控于物源供给的影响，距离三角洲砂体朵叶越近，滑塌浊积体数量越多，面积也越大。总体上，滨岸三角洲前缘亚相、深水扇中亚相和滑塌浊积体是研究区良好的储集相带，该类储集体由于埋藏较深加之被泥岩覆盖，对油气聚集较为有利。
Abstract:The Jurassic strata in the Chaoshan sub-basin of northern South China Sea have great potential for oil and gas exploration, and the sedimentary characteristics have obvious effect on the development of the reservoirs.Based on analyzing the latest seismic data of the study area, the authors recognized four typical seismic reflection interfaces and three seismic reflection layers and, according to the result of the sequence interface, figured out the Jurassic distribution and residual thickness. On the basis of the comparative analysis of the transformation of seismic facies-sedimentary facies, the authors determined the sedimentary facies types and distribution characteristics of the Jurassic strata in different periods and reshaped the sedimentary evolution history of the Jurassic sediments in the Chaoshan sub-basin. The study area has mainly developed five sedimentary facies and eight kinds of sedimentary subfacies, and the coastal delta front subfacies and deepwater middle-fan subfacies have controlled the development of high-quality reservoirs of the debris flow sandstone separately. In addition, the turbid sandstone reservoir is mainly controlled by the sediment supply, the more closer to the delta sand body leaves, the more the number of slump turbidite, and the larger the area. In general, the front subfacies of the delta, the subfacies of the deep water fan and the gravity flow slip turbulence constitute the facies of high-quality reservoirs in the study area. The reservoirs are fairly favorable for oil and gas accumulation due to the deep burial and the mudstone cover.
