吐玉克油田生物降解特征与规律

BIODEGRADATION CHARACTERISTICS AND REGULARITY OF TUYUKE OIL FIELD

本文依据吐玉克油田原油生物标志化合物的分析成果,总结出了该油田生物降解的基本特征和客观规律,并结合该油田的构造特征,提出该油田在后期改造中受到了风化氧化和底水氧化两种作用的影响。

On the basis of the research about biodegradation of Tuyuke heavy oil deposits,the effective biomarker index used for correlation and evaluation is determined,and the regularity about the degradation existed in this Oilfield has been concluded.With the structure characteristics of this Oilfield,we think that Tuyuke Oilfield will be affected by weathering oxidation and bottom water oxidation on the period of final modification.
