塔河油田碳酸盐岩储层测井评价方法研究

对塔河油田的碳酸盐岩储层测井评价方法进行了回顾总结,具体涉及综合概率模型、声波全波测井、声波井壁成像测井及油气水判断等四个方面,认为所取得的成果具有实用价值,并对进一步的研究工作有重要借鉴作用。强调对裂缝性储层的划分应综合应用成像测井与综合概率模型。成像测井应在裂缝产状、沉积构造描述和区分有效与无效裂缝方面进一步深入研究;综合概率模型应补充新的指标,并按岩性将指标优化组合。在提高裂缝识别与评价精度、储层参数评价方法研究、储层空间展布研究等三个方面提出了今后的工作设想。

Investigation of Well Logging Evaluation Methods for Carbonate Reservoirs in Tahe Oilfield, Tarim Basin

In Tahe Oilfield,well-logging evaluation methods for carbonate reservoirs generally deal with the comprehensive probability model,the sonic full waveform data,the acoustic borehole- imaging data and the oil/gas/water judgement.Based on hav- ing reviewed these current evaluation methods,the author be- lieved that the application of these methods is achievable and available to the future further research.It is emphasized that conventional borehole-imaging data and comprehensive proba- bility model should be integratively applied to classification of fracturing reservoirs.Some study methods are proposed for improving fracture identification and evaluation reliability,the reservoir parameter evaluation,and reservoir spatial distribu- tion.
