Prediction of favorable reservoir in granite weathering-crust buried-hill type—A case study of the Baoyunting area on Pinghu slope
-
摘要:
平湖斜坡是东海盆地西湖凹陷的油气重点勘探区域，随着勘探开发的不断深入，深部和基底潜山油气藏成为重要的油气勘探接替领域。为进一步指导该区油气勘探，综合利用录井、测井、地震、岩心与实验分析等多种资料，对平湖斜坡宝云亭油气区花岗岩潜山储层发育主控因素及有效储层分布开展研究。结果表明，矿物成分为花岗岩储层的形成提供物质基础，风化淋滤控制溶蚀孔隙形成，构造活动形成大量裂缝提升储层物性，三者共同控制着花岗岩潜山储层展布。利用古地貌恢复、蚂蚁体属性提取等手段，预测风化溶蚀强度和裂缝发育程度，对宝云亭油气区花岗岩潜山储层进行了综合评价。
Abstract:Pinghu slope is the key exploration area of oil and gas in the Xihu Sag, East China Sea basin. With the deepening of exploration and development, buried-hill-typed reservoirs in deep and basement have become an important target. To promote the exploration, the main controlling factors and favorable reservoir distribution of granite weathering-crust buried-hill reservoirs in the Baoyunting area of Pinghu slope were studied comprehensively using various data including logging, seismic, core, and experimental analysis. Results show that the mineral composition provided material bases for the formation of the granite weathering-crust buried-hill–typed reservoir; leaching controlled the formation of dissolution pores; and tectonic activities generated many fractures. These factors improved the physical properties of the reservoir, and jointly controlled the distribution of reservoirs in the buried-hill type. In addition, using paleogeomorphic restoration and ant body attribute extraction, the weathering and dissolution intensity and fracture development degree were predicted, and finally the granite buried hill reservoirs in the Baoyunting oil-gas area was evaluated in overall.
