Intelligent Analysis of the Fracturing Sand Control Project Based on the Expert System

Fracturing sand control is a complex sand prevention method. There are so many influence factors which can not be modeled by the structuring models in both the decision and the operation process. Expert system for the optimization design of the fracturing sand control can simulate the thinking patterns of those experts, collect the computer knowledge and models in the field, apply the fuzzy mathematics to the project design, deal with the uncertain parameters using fuzzy set theory, and qualify such parameters to achieve analogy reasoning. Thus, an intelligent analysis system is established, which can carry out analogy analysis and decision making based on the cases in engineering database and experiences in knowledge base, modify the parameters related to fracturing sand control by comparing different operation parameters and analogy reasoning, select the reasonable operation parameters, provide the feasible operation project, perform evaluation on the project and forecast the final result. Such a system can eliminate the hidden troubles during the operation, improve the scientific value of the operation and ensure the operation quality.
