The mutation detection is an effective identification method of well logging curves, which can be utilized to detect mutations of the correlation time series by a sliding window technology. The computational complexity and accuracy of mutation detection are very important for detecting the series change points, however, some of the existing calculation methods take none of these into account. By sliding...
Focusing on the users is more interested in the sequential patterns that accord with the well completion business process habit overall in the web access mode of well completion mobile platform. This paper proposed a weighted sequential pattern mining algorithm based on the well completion business process. With analyzing the business process models and web access log of well completion, confirm the...
According to the characteristics of post evaluation for the productive capacity construction project of oilfield and the actual situation of oilfield, detailed analyzed the evaluation index, the relationship and the impact to the Comprehensive Post Evaluation of the post evaluation for the productive capacity construction project of oilfield, proposed the comprehensive post evaluation model based...
A novel integrated framework for knowledge building of the oil field downhole operation is introduced based on the problems that the loaded data resources, poor knowledge sharing and decision support in this paper. Elementary techniques of the framework are elaborated in details, and an oil field ontology prototype system is drawn up and implemented based on the framework. The oil field downhole operation...
The paper introduces ontology into knowledge construction of petroleum exploitation domain in order to solve problems on information sharing and application integrating which are caused by the inconsistence of information terms between disciplines. Through the formal description of ontology, this paper puts forward an improved method of ontology mapping, designs an ontology integration platform of...
The type of sedimentary facies in oil fields is a primary factor affecting the performance of the reservoir accumulation. The sedimentary facies research is the indispensable foundation work in process of exploring and developing the oil fields, which is determined by the many kinds of generalized analysis methods such as the geology, the earthquake, the oil well logging and so on. The technology...
