Abstract: The changing characteristics of oilfield development index are regarded as the important basis of oilfield development planning, oilfield exploitation evaluation, oilfield development scheme design and adjustment, decision management problems of oilfield development risk prediction and early warning, etc. For one of the unsolved bottleneck problem of building intelligent oilfield, i.e. the problem on knowledge mining of selecting prediction method and model of oilfield development indexes intelligent prediction system, based on the massive data of oilfield development, this paper uses the convolutional neural network and cyclic neural network of deep learning to extract the characteristics and knowledge reflecting the development dynamic of oilfield. On this basis, combining the model base and knowledge base of oilfield development index prediction, a knowledge mining method to select the optimal prediction model of oilfield development index is proposed through the input information and dynamic characteristics index of oilfield development, the model base and the knowledge base of oilfield development index prediction by using the joint extraction method of entity and relationship of deep learning. The simulation example of conceptual design shows that the proposed knowledge mining process may realize autonomous obtaining an appropriate prediction model of oilfield development index as long as inputting relevant information of oilfield development.
