摘要:
川東北地區須家河組須三段陸相碎屑巖沉積儲集巖石成分和結構復雜、物性條件差、非均質性強,常規測井參數解釋模型技術在應用中受到限制。針對川東北地區須家河組儲層的特點和難點,建立一套以元素俘獲譜測井(ECS)為基礎測井評價方法。元素俘獲譜測井利用快中子與地層中的原子核發生非彈性散射碰撞及熱中子被俘獲原理,通過解譜和氧化物閉合模型得到地層中主要造巖元素的相對百分含量,并應用聚類分析、因子分析等方法定量求解地層的各種氧化物含量。在此基礎上,建立儲層巖石骨架屬性、計算孔隙度、飽和度等儲層綜合評價。該方法在川東北地區須家河組致密砂巖儲層評價中具有指導意義。
Abstract:
Continental clastic reservoirs of Xu 3 Member of Xujiahe Formation in northeastern Sichuan Basin have complex rock composition and structure, poor physical properties and strong heterogeneity, and can't be well interpreted by a conventional logging parameter model. Based on this study, a log evaluation method has been established based on element captured spectra(ECS)log data. Following the principle of that elastic scattering collision takes place between fast neutrons and formation nuclei and then thermal neutron are captured, the ECS logging method can get the relative percent of primary elements in formation by spectral decomposition and an oxide closure model; then the contents of various oxides in formation can be quantitatively calculated by cluster analysis and factor analysis; and finally, reservoir evaluation can be carried out, involving porosity and saturation, properties of rock skeleton etc. Field application has proved that this method has guiding significance in the evaluation of tight sandstone reservoirs of Xujiahe Formation in northeastern Sichuan.
