摘要

针对红山油田蒸汽吞吐开发过程中CO生成量超标的问题

开展了相应的室内研究工作。通过物理模拟及多参数敏感性分析研究了蒸汽温度、注汽量、焖井时间等工艺参数对于CO生成量的影响规律

并根据工艺参数交互作用下CO的产出规律提出了相应的防治措施建议。结果表明：蒸汽温度、注汽量、焖井时间三个工艺参数中蒸汽温度是影响最大的主控因素

注汽量影响其次

焖井时间影响最小;降低蒸汽温度可以有效减少CO的生成量

但蒸汽温度降低至220 ℃以下时原油产量会受到较大负面影响。因此

对于红山油田CO超标程度相对较低的井

建议将蒸汽温度降低至220 ℃使CO生成量降低至安全范围以下

对于CO超标程度相对较高的井

建议将蒸汽温度降低至220 ℃以下

同时增大注汽量

在降低CO生成量至安全范围以下的同时保证周期采油量不发生明显的降低。

Abstract

In order to solve the problem of excess production of carbon monoxide in cyclic steam stimulation process of Hongshan oilfield

the corresponding laboratory researches have been carried out. Through physical simulation experiments and multi-parameter sensitivity analysis

the effect of technological parameters such as steam temperature

steam injection volume

and soaking time on carbon monoxide output concentration have been investigated. Furthermore

the possible solutions for carbon monoxide production have been proposed based on the effects of different factors. The results show that the influencing order of the three dominant factors is steam temperature

steam injection volume and soaking time. Reducing the steam temperature can effectively reduce the carbon monoxide output concentration

but when the steam temperature drops below 220 ℃

the crude oil production will be adversely affected. Therefore

for the wells in Hongshan oilfield with relative low carbon monoxide exceeding degree

it is recommended to reduce the steam temperature to 220 ℃ to keep the carbon monoxide concentrations below safe levels; for those ones with relative high exceeding degree

in addition to the above measures

the steam injection volume should be increased to ensure that the periodic oil production does not decrease significantly.
