油田为确保增产,实施了不同形式的措施作业,但部分措施油井项目取得的效果并不理想。为准确分析措施油井项目的质量异常原因,首先,阐述了措施油井项目质量控制概念和质量指标集;其次,利用主成分分析法、Q-Q图和二元主成分质量椭圆构建措施油井项目质量控制方法;最后,将该质量控制方法应用于胜利油田营十三断块某油井并提出质量控制建议。应用结果表明该质量控制方法能够满足稳定和提高油井质量的要求,为油田企业控制措施油井项目质量提供了一种新思路。
In order to ensure the increase of output, the oilfield has implemented different forms of measures and operations, but some measures have not achieved satisfactory results in well projects. In order to accurately analyze the causes of the anomalies in the quality of the oil well project, firstly, the concept and quality index set of the quality control measures for the oil well project are expounded. Secondly, using the principal component analysis, the QQ graph and the binary principal components quality ellipse construction measures, Finally, the quality control method was applied to a well in Block 13 of Shengli Oilfield and proposed quality control suggestions. The application results show that the quality control method can meet the requirements of stability and improve the quality of oil well, and provide a new idea for the quality control of oil well project in oilfield enterprises.
