录井解释评价技术面临的困难与挑战

随着油气勘探开发对象愈来愈复杂，录井技术对复杂地质及特殊钻井条件下的油气水层解释评价难度越来越大。以大庆录井为例，就实现精细解释与定量评价目标而言，阐述了解释评价技术面临的困难，分析了困难形成的原因，明确了解决困难相应的对策。强调指出薄弱的数据处理技术是制约解释评价技术发展的“瓶颈”，而要解决这一问题，首先要实现录井采集数据的标准化处理；其次是求取反映岩性、储集层物性、含油气水性以及地层压力等特征的多项综合性参数，建立单井纵向连续的评价剖面。最后从3个方面，探讨了“十一五”期间录井解释评价技术应分阶段开展的重点工作。

Difficulties and challenge faced with mud logging interpretation and evaluation technique

As the oil-gas exploration and development objects are becoming more and more complicated, the difficulties of oil-gas-water layer interpretation and evaluation in mud logging technology under the special drilling conditions have become more and more great. Taking Dazing mud logging realizing the object of fine interpretation and quantitative evaluation as an example, the paper expounded the difficulties confronted with interpretation and evaluation technique, analyzed difficulty forming reasons and clearly defined the appropriate countermeasures of solving these difficulties. The paper emphasized to point out that the weak data processing technique was the bottleneck of restraining interpretation & evaluation technique development. For solving this problem, first realizing mud logging acquisition data standardization processing, secondly evaluating multiple comprehensive parameters, which reflect the features of lithology, reservoir physical property, the properties of oil-gas-water bearing, formation pressure etc., and setting up a single well evaluation profile that is continuous in vertical, lastly from three aspects, the paper discussed the key jobs that should be carried out by mud logging interpretation & evaluation during the 11th five-year development guidelines.
