          摘要:
          南堡油田館陶組至東一段主力開發層系的砂巖儲層富含鈣質,造成應用常規測井資料和碳氧比測井資料識別儲層流體存在困難。針對性地研究與應用了PNST碳氧比測井資料的鈣質校正方法。按照PNST測井儀和當地套管井實際結構建立模型,通過MCNP數值模擬,獲得了碳氧比和俘獲鈣產額測井值隨地層巖性和孔隙度變化的規律。可利用俘獲鈣產額曲線校正鈣質含量對碳氧比曲線影響,提高含油飽和度解釋準確性。應用鈣質校正方法后,PNST含油飽和度測井解釋成果為南堡油田制訂堵水、補孔方案提供了有效依據,90%以上的井措施后增油明顯。測井實例顯示,PNST測井資料在南堡油田能夠準確識別油水層。
          Abstract:
          Abstract: The calcium-rich sandstone reservoirs in the main development zone from the Guantao Formation to the first interval of the Dongying Formation in Nanpu Oilfield bring challenges to identify formation fluids using conventional logging data and carbon-oxygen ratio logging data. To address the issue, the calcium correction method for PNST carbon-oxygen ratio logging data was studied and applied. Model was established according to the PNST logging tool and actual wellbore structure. The variation of carbon-oxygen ratio and capture calcium yield logging with lithology and porosity of the formation was obtained by MCNP numerical simulation. The capture calcium yield curve can be used to correct the influence of calcium content on the carbon-oxygen ratio curve and improve the accuracy of oil saturation interpretation. By applying the calcium calibration method, the PNST oil saturation logging interpretation results provide an effective basis for the development of water blocking and infill perforating schemes in Nanpu Oilfield. More than 90% of the well showed significant oil recovery after stimulation. Well logging case study showed that PNST logging data can accurately identify oil and water layers in Nanpu Oilfield.
