【摘要】：流体录井系统相对于以前的气体色谱在分析技术和方法上有了很大的提高。传统气体色谱技术分析烃类组分包括C1、C2、C3、iC4、nC4、iC5和nC5,流体录井系统检测组分范围不仅包含了以上几种组分,并且扩展到了nC6、nC7、nC8、C6H6,C7H8、C7H14以及非烃类CO2和H2S等组分,如何有效的利用这些扩展的组分结合原来的气体组分,让其更好的为气体解释和油田的勘探开发服务成为了流体录井技术更好发展的关键所在。随着海洋石油981深水钻井平台的投入使用,海洋石油对深水区的勘探进入大规模勘探开发时期,所以总结好流体录井在深水区的解释图版和模型,对以后白云凹陷尤其白云凹陷深水区有着非常重要的意义。本文研究对象为白云凹陷所钻23口井的243层储集层的资料,从统计学的角度出发,对储集层气体进行分析整理,结合气体组分各个参数的特点,研究出了组分趋势线对比法、全烃-流体类型法和异常倍数法对油气层进行快速识别。这三种方法进行对比,异常倍数法符合率最高,对试油和电测取样的39层进行分析,有3层不符合,符合率为92.3%,效果非常令人满意。针对在超深水井(水深1500m)CO2气藏气测CO2检测仪无明显异常的情况,提出了录井、测井、钻井液综合解释分析的方法。
[Abstract]:Compared with the previous gas chromatography, the fluid logging system has been greatly improved in analytical techniques and methods. Conventional gas chromatographic techniques have been used to analyze hydrocarbon components, including C _ 1C _ 2C _ 2C _ 3i _ C _ 4nC _ 4C _ 4C _ 5 and NC _ 5. The range of components detected by fluid logging system not only includes the above components, but also extends to the components of nC6nC7nC8H6H6C6H8C7H14 and non-hydrocarbon CO _ 2 and H _ 2S, etc. How to effectively use these extended components combined with the original gas components, so that better gas interpretation and oil field exploration and development services has become the key to better development of fluid logging technology. With the application of the offshore oil 981 deepwater drilling platform, offshore oil exploration in deep water area has entered the period of large-scale exploration and development, so the interpretation chart and model of fluid logging in deep water area are summarized. It is of great significance to the deep water area of Baiyun sag, especially Baiyun sag. The object of this paper is the data of 243 reservoir in 23 wells drilled in Baiyun sag. From the point of view of statistics, the gas of reservoir is analyzed and sorted out. According to the characteristics of each parameter of gas composition, the method of contrast of component trend line is studied. Total hydrocarbon-fluid type method and anomaly multiple method are used to identify oil and gas reservoir quickly. Compared with these three methods, the coincidence rate of abnormal multiple method is the highest. The analysis of 39 layers of oil test and electric sampling shows that there are 3 layers that do not match, the coincidence rate is 92.3, and the effect is very satisfactory. In view of the fact that there is no obvious anomaly in the CO _ 2 detector of CO _ 2 gas reservoir in the ultra-deep well (water depth of 1500m), the method of comprehensive interpretation and analysis of logging, logging and drilling fluid is put forward.
