摘要

为了解原生水在烟油高温氧化升级过程中作为氢源的作用，利用锥形管进行了两种不同的原位燃烧实验，分别以重水(D2O)和O-18富集水(H2O18)作为原生水。除了对这些反应在原位燃烧中的作用有了基本的了解外，这些结果还可能有助于优化原位制氢和重质油和沥青油的升级。锥形管以前被用于了解空气通量(AF)对维持燃烧前沿的影响(Alamatsaz et al. 2011)。在这些测试中，与原始沥青重力为9°的API相比，生产的API重力达到35°，效果显著。本文(A部分)讨论了实验结果，包括锥形管和燃烧管(CT)结果的比较。随后的论文(B部分)将讨论升级方面和质谱分析结果。

A Novel Approach in Understanding the Role of Water in Oxidation and Upgrading Reactions during In-Situ Combustion Oil Recovery, Part A: Experimental Observations

To understand the role of connate water as a source of hydrogen in oxidation and upgrading of bituminous oil at high temperature, heavy water (D2O) and O-18 enriched water (H2O18) were used as connate water in two different in-situ combustion experiments using a conical tube. Aside from fundamental understanding of the role of such reactions in in-situ combustion, the results could also potentially help in optimizing in-situ hydrogen generation and upgrading of heavy and bituminous oil. The conical tube had previously been used for understanding the impact of air flux (AF) in sustaining the combustion front (Alamatsaz et al. 2011). Significant upgrading was observed in these tests with a produced API gravity of 35 ° compared to the original bitumen gravity of 9 °API. This paper (Part A) deals with the experimental results including a comparison between conical tube and a combustion tube (CT) results. A subsequent paper (Part B) will discuss the upgrading aspects and the mass spectrometry results.
