生烃动力学模型不仅可用于生烃规律预测还可应用于盆地模拟、油气藏等成因,尤其是近年在此基础上发展起来的碳同位素动力学方法,能应用于油气形成过程、运移与聚集、油气资源量预测,但是生烃动力学模型参数的确定直接影响了预测的准确性。基于此,采用改进的遗传算法,对新疆某油田的数据进行动力学参数进行优化,经过Matlab编程计算,拟和误差明显提高,而且,很好地解决了初值不好选取的问题。
Hydrocarbon generation kinetic model not only can be used to predict hydrocarbon generation, but also can be applied to basin modeling, oil and gas reservoirs and other causes, especially the carbon isotope kinetics developed on this basis in recent years, which can be applied to hydrocarbon formation, migration and Aggregation, prediction of oil and gas resources, but the determination of hydrocarbon generation kinetic model parameters has a direct impact on the accuracy of prediction. Based on this, the improved genetic algorithm is used to optimize the dynamics parameters of a field in Xinjiang. After Matlab programming, the fitting error is obviously improved, and the problem of poor initial value selection is well solved.
