塔河油田4区奥陶系碳酸盐岩潜山油藏储层预测
|
摘要
碳酸盐岩潜山油藏储集空间类型多样,孔、洞、缝相互配置及储层发育受多种因素控制,在三维空间分布很不稳定,非均质性极强,定量预测的难度大。在地质综合研究基础上,综合应用相干数据体分析、稀疏脉冲地震反演、随机模拟地震反演等多项技术,对新疆塔河油田4区奥陶系碳酸盐岩潜山油藏进行了研究,分类描述出未充填-半充填溶洞型储层、Ⅰ类储层、Ⅱ类储层在三维空间的展布,经后期钻井证实预测结果与实钻情况比较符合。该方法在碳酸盐岩潜山油藏储层定量预测方面是行之有效的。
The distribution of carbonate reservoirs with strong heterogeneities and difficulty to quantitative prediction is unstable in 3D space due to the various types of reservoir space with different allocation of voids, vugs and fractures and the multiple factors governing the development of the reservoirs. Based on comprehensive geologic researches, multiple techniques of coherent data volume analysis, sparse spike seismic inversion, stochastic simulation seismic inversion etc. had been used to make research on Ordovician system carbonate reservoirs of Tahe No. 4 area,Xinjiang Oilfield. As a result, the spread situations of the carbonate reservoirs with non -packing to semi -packing solution cavity,type Ⅰ and type Ⅱ were described respectively. The drilling in later period proved that predictive result coincided well with practical drilling and the more ideal result was achieved. The method was effective for quantitative prediction in the buried hill carbonate reservoirs.
