| 摘 要： | 低孔低渗储层由于其成因复杂,测井响应影响因素众多,导致解释结论具有多解性,测井识别和评价都存在极大的难度。而(脉冲中子-中子)PNN测井技术在套后进行测井评价,能较好地消除低孔低渗储层泥浆侵入的影响,利用油水俘获截面的差异可以准确识别油水层。通过对柴达木盆地西部南翼山油田Ⅲ、Ⅵ层组物性资料分析研究,结合PNN测井技术建立了针对低孔低渗储层的储层识别及评价解释方法。实际生产证明,PNN测井技术在南翼山油田低孔低渗储层识别评价中效果较好。

| Abstract: | Because of complex genesis in low permeability and low porosity reservoirs,logging in those areas were influenced by many factors,so it caused great difficulty in logging identification and evaluation.The evaluation of PNN logging was evaluated after casing setting,so it could avoid the impact of mud invasion effectively.Based on the difference of oil and water captured section,oil and water layer could be recognized accurately.In combination with PNN logging,method was established for evaluating and recognizing the reservoirs with low porosity and low permeability.Production demonstrates that PNN log technology is used in low permeability and low porosity reservoirs and better effect is obtained. |
