摘要:
火山巖物性評價中,黏土化蝕變火山巖孔隙度的定量計算一直是測井解釋難題。通過對研究區25口井的測錄井資料、薄片分析、全巖礦物等進行分析,優選出對黏土化蝕變反映較為敏感的測井曲線。在測井系列分析的基礎上,優化黏土化蝕變指示因子,建立了研究區黏土蝕變程度指數模型,利用黏土蝕變程度指數對黏土化蝕變火山巖的黏土含量進行定量計算,利用體積模型對黏土化蝕變的火山巖孔隙度進行計算。計算結果與分析孔隙度進行對比,精度得到大大提高。該方法較好地解決了黏土化蝕變火山巖孔隙度定量評價問題,對火山巖儲層試油選層、油氣藏精細評價及后期勘探開發提供了一定的理論參考依據。
Abstract:
The quantitative calculation of clay-altered volcanic rock porosity has always been a difficult problem in log interpretation. By analyzing the log data, thin section analysis and whole rock analysis of 25 wells in the study area, the logging curves which were sensitive to the reflection of clay alteration were optimized. Based on the analysis of logging series, the indicative factor of clay alteration was optimized, the index model of clay alteration degree in the study area was established, the clay content of clay altered volcanic rock by using the index of clay alteration degree was quantitatively calculated, and the porosity of volcanic rock with clay alteration by using volume model was calculated in this paper. By comparing the porosity of core analysis, the accuracy of porosity calculation was greatly improved. This method solved the problem of quantitative evaluation of porosity for clay altered volcanic rock and provided some theoretical reference for the selection of test, the fine evaluation of oil and gas reservoir and the exploration and development of the later stage of volcanic reservoir.
