Resarch Of Real-time Monitoring System For Offshore Fracturing

Recently,along with the continuously development of offshore oil and gas field,In order to increase output of offshore oil and gas production,The application of fracturing technology is gradually increasing.Because of the particularity of offshore fracturing technology,The real-time monitoring system for offshore fracturing is very significant important.The study of real-time monitoring of offshore fracturing has important practical significance.In this paper,based on the characteristics of offshore fracturing.Summarized the experience of typical offshore fracturing,analyzed the typical fracturing characteristics and as a basis for design the framework of real-time fracturing monitoring system.Firstly,summarized the typical characteristics of fracturing,common problems and solutions of fracturing,the methods of fracturing monitoring and using ABAQUS to study on the rule of crack extension that has natural fractures.Secondly,applied the method of case-based reasoning and the arithmetic of disperse Fréchet distance improved to analyze similarity of fracturing curve,selecting the appropriate threshold,realized real-time interpretation of fracturing and put forward the method to explain as well as optimize fracturing.Lastly,designed the framework of Real-time monitoring system,introduced reasoning of module,module testing with the filed fracturing data,validated the feasibility of real-time monitoring system of fracturing.
