摘要:
針對火山巖儲層裂縫孔隙度定量求取這一問題,為充分利用地層微電阻率成像測井(FMI)資料,論述了已有的軟件人機交互解釋求取方法和圖像特征提取求取方法,并提出一種基于采集數據陣鄰域搜索的求取方法。以巖心分析得到的總孔隙度值與聲波得到的巖塊孔隙度值之差作為標準值,分析人機交互解釋、圖像特性提取、基于采集數據矩陣建模等3種求取裂縫孔隙度的求取效果。對比長嶺地區3口井17個深度點的裂縫孔隙度計算結果,得出第1種方法依賴解釋者的主觀經驗,計算結果大小不定;第2種方法只對標準正弦形態裂縫有效,計算結果偏小;第3種方法將全部低電阻率響應劃入,計算結果偏大。
Abstract:
It is very difficult to quantitatively acquire the fracture porosity of volcanic reservoir. To take full advantage of microresistivity imaging log (FMI) data, expounded are the existing ways about interactive interpretation and image feature extraction, and put forward is a new method to calculate the fracture porosity of volcanic reservoir which is based on collecting data array neighborhood search. We take the differentials between the total porosity values from the core analysis and rock porosity values from the acoustic logging as the standard value to analyze the calculations of the above methods. Through the comparison of calculations about the fracture porosity from 17 depth points of three wells, we could get the conclusion: The first method relies on subjective experience of personnel, the calculations are not sure; The second method is only effective for the standard sine form fracture, the calculations are smaller; The third method includes all the low resistivity responses, the calculations are larger.
