前进地区沉积特征研究

Study on sedimentary characteristics in advance area

随着勘探程度的加深,目前勘探工作已进入中高成熟阶段,寻找新的探明储量所面临的困难越来越严峻,在老区勘探面临瓶颈的现状下,老区扩边是下一步的重点勘探方向。尤其沙三段砂岩油藏沉积特征一直认识不清,如何通过测井识别技术,搞清单井的沉积微相,从而认识该块的沉积特征,找到老区挖潜的目标区,从而指导井位部署工作,实现开发区块的滚动扩边。

With the deepening of exploration,the exploration work has entered the middle and high maturity stage.The difficulties faced by finding new proven reserves are becoming more and more serious.Under the current situation of bottleneck exploration in the old area,the extension of the old area is the next key exploration direction.In particular,the sedimentary characteristics of Sha three member sandstone reservoir have not been clearly understood.How to identify sedimentary microfacies in single well by Logging Recognition Technology?In order to understand the sedimentary characteristics of the block and find out the target area for tapping the potential in the old area,it will guide the well location deployment and realize the rolling expansion of the development block.
