基于范例推理的控压钻井方式评价

提出一种基于范例推理的控压钻井选型方法。首先大量调研成功实施控压钻井的实例为源数据库,然后根据范例推理理论建立控压钻井选型模型,利用该模型对三个区块不同地层进行控压钻井选型研究,得出具体的计算结果,并且对选型结果进行评价。通过基于范例推理的控压钻井选型研究将钻井工程与范例推理有机结合,对解决钻井工程领域不确定性问题提供一种有意义的尝试。使范例推理在具体的工程应用向前迈进了一步,并且为控压钻井适应性分析提供一种全新的研究方法,在学术和钻井工程应用上具有重要的价值。

Evaluation of the Managed Pressure Drilling Based On Case-Based Reasoning

Come up with a way of managed pressure drilling (MPD) lectotype based on case-based reasoning. Firstly, choose a large number of the successful applications of MPD as the source database. Then, build the MPD lectotype model based on the case-based reasoning theory. Finally, use the model to research on the MPD lectotype for the different formations of three blocks, get the concrete calculation results and evaluate the lectotype results. The MPD lectotype method based on the case-based reasoning makes drilling engineering and case-based reasoning integrate well. The method is a very meaningful attempt to solve the uncertainty in the drilling field, also, it makes the application of the case-based reasoning better and provides a brand-new research method to analyze the MPD adaptability. The MPD lectotype has significant meaning in the academic study and engineering application.
