中文摘要 | 進行臺灣某盆地某構造主要儲集岩體之電測解釋,並將計算結果之孔隙率,滲透 率與岩心分析結果比對( Calibration ), 建立儲集岩體基本之岩石物理模型( petrophysical model )以便有效而正確的描述儲集岩特性,進而進行客觀之蘊藏量預估。 初步建立臺灣某盆地某構造 F 斷層以南 C-16 附近先漸新統之岩石物理模型, 其岩心深度 +3 公尺即為電測資料深度, 其岩心分析之孔隙率與電測計算值對比之相關係數為 0.6; C-16 岩心分析之滲透率值,大部分均小於 DST 分析結果達十倍以上,可能是受自然裂縫存 在之影響。 應用所建立之岩石物理模型於 C-11、S-1 及 S-5, 除 C-11 之比對比較好外,其餘比對之 相關性均極低,在孔隙率方面可能是受岩性變化之影響;在滲透率方面可能是受自然裂縫發 達與否之影響。 |
英文摘要 | Study of the well log data of the offshore basin of Taiwan, creates a petrophysical model by calibrating the log-derived porosity and permeability with core data. This model enables a better and more effective reservoir description of the study area. To create a preliminary petrophysical model for the Pre-Oligocene Sand of the well CX-16 of the south of the F fault of the study basin. The core depth ought to plus 3 meters for corresponding the log depth, and the correlation coefficient of the porosity crossplot of core and log is 0.6. The permeability value of core which is almost 10 times less than DST analysis result may be due to the existence of fractures in reservoir. Applying this preliminary petrophysical model to the CX-11, SX-land SX-5, the correlation of the CX-11 well is fair, and the others is poor; The low porosity correlation may be caused by the lithology change and the low permeability correlation may be due to the nature fracture of reservoir. |
