摘要:
CFD油田1井区东三段砂砾岩储层砂体厚度大,岩性复杂,储层非均质性强,优质储层展布认识不清,制约了下一步的开发部署。通过岩心观察描述,将东三段岩石划分为细砂岩、中粗砂岩、含砾砂岩和砂砾岩4种类型。根据中子、密度和重构中子测井响应特征,建立了岩相定量识别标准; 用聚类分析法对1井东三段的岩石类型进行了连续识别。对不同岩性储层的渗透率进行优化解释,提高了储层渗透率解释精度。在沉积模式指导下,用井震结合层序地层划分与对比方法进行扇三角洲沉积期次划分,搭建等时地层格架; 以地层格架为单元,使用地震多属性分析技术和波形分类的地震相分析技术预测了有利储层的空间分布范围。
Abstract:
Conglomerate reservoir of Dongsan member in 1 wellblock of CFD Oilfield is characterized by large thickness of sandbodies, complicated lithology, strong heterogeneity and unclear distribution of good quality reservoirs, which restricts further development. Rock types of the Dongsan member in this area were divided into four types by the detailed observation of cores. Quantitative identification standards of rocks were set up according to the response characteristics of density, neutron and neutron reconstruction loggings, and the rock types developed in Dongsan member of 1 wellblock were identified by the cluster analysis method. Guided by the sedimentary and geology characters, based on well-seismic combination of high-precision sequence stratigraphy, it was identified different sedimentation stages of fan deltas and established a stratigraphic framework. By taking the stratigraphic framework as units, it was predicted spatial extent of favorable reservoir through seismic analysis and seismic waveform classification technique.
