摘要
研究了烃源岩低温催化混合酯生烃反应的影响因素,设计了合理的正交实验,并通过极差分析确定了各影响因素的显著性大小顺序。并在此基础上进行了灰色关联分析,分别计算了各影响因素对混合酯生烃率的绝对值关联度和速率关联度,利用该关联度大小判断的各因素对混合酯生烃率影响的顺序与极差分析得到的顺序一致,即温度(pH值(压力(盐度。
Influence factors of hydrocarbon generation from mixed esters catalyzed by source rock at low temperature were studied and orthogonal experiment was designed reasonably. The extent of significance of each influence factor was sequenced by means of range analysis. Based on this, the gray relation analysis was carried out. The absolute value relation degree and rate relation degree of influence factors on hydrocarbon generation ratio of mixed esters were calculated. The sequence of influence factors judged by relation degree coincides with the one judged by range analysis. The order is temperature 〉 pH value 〉 pressure 〉 salinity.
