摘要
套损预报是石油工程中的一大技术难题,在充分考虑套管损坏影响因素多,机理复杂的前提下,提出了基于支持向量机的套损预报方法。通过对历年套管状况及其影响因素的学习,建立了支持向量机套损预报模型,运用所建立的模型对套管状况进行预报。结果表明:该方法计算效率高,结果可靠,实现了油水井正常生产过程中对套管状况进行动态判断,具有广泛的应用前景和工程价值。
Casing damage predicting is a difficult technical problem in Petroleum Engineering,base on thorough considering many influencing factors of casing damage and complex mechanism,the method of support vector machine about casing damage predicting is proposed.The support vector machine predicting model is established through data over the years,and the model is applied to predicting practical casing condition.Application results show the new method is effective and dependable,and dynamic casing state judgment is achieved through this new method in normal production,the new method has extensive application circumstance and engineering value.
