摘要:
地層元素測井技術以各種已知元素的特征能譜為基礎,通過譜剝離處理及氧化物閉合模型得到了地層中元素百分含量,在此基礎上進行成巖礦物含量計算、劃分地層巖性、確定巖石骨架參數。結合鄂爾多斯盆地隴東地區長7段儲層常規測井資料,利用骨架密度和Lambda滲透率模型計算長7段致密砂巖儲層孔隙度和滲透率,提高儲層參數計算精度;诘貙釉匕俜趾拷N源巖總有機碳含量TOC計算模型,計算結果與巖石物理實驗分析結果基本一致。地層元素測井技術在致密砂巖儲層中適用,為致密砂巖儲層測井識別及評價提供有效手段。
Abstract:
The Formation Element and Mineralogy(FEM)logging technology is based on the spectral characteristic of various known elements. Through spectral stripping and oxide closure model, the element content in the formation can be obtained. Furthermore, the caculation of diagenetic mineral content, the classification of formation lithology and the determination of rock skeleton parameters can be conducted. Combined with conventional logging data of Chang7 member reservoir in Longdong area of Ordos basin, the veracity of the calculated reservoir parameters, such as porosity and permeability of tight sandstone reservoir in Chang7 formation, is highly improved by using skeleton density and Lambda permeability model. The TOC calculation model of source rocks is established based on the element contents of formations. The calculation results are basically consistent with the petrophysical experimental analysis results. FEM logging technology is applicable to tight sandstone reservoirs and provides an effective method for identification and evaluation of tight sandstone reservoir.
