SELECTION METHOD FOR OIL & GAS DRILLING CORE TECHNOLOGY

Oil gas drilling is faced with many new challenges in 21st century. Selection of oil gas drilling core Technology is very important to scientifically and reasonably lay down scientific-technical development strategy in oil gas drilling. Considering the strategy aim of land petroleum development in China, this paper established a qualitative and quantitative evaluation index system for evaluating oil gas drilling core technology. Based on expert surveys and many literatures, and combined qualitative analysis and quantitative calculation, this paper applied Delphi method to select and predict the oil gas drilling core technology in about 5-10 years, and introduced the process and steps of selecting oil gas drilling core technology. For quantitative evaluation index system, weight value of each index is obtained by the weight factor decision method. Its calculation is simple and practicable. This selection method overcame the shortcomings of qualitative method and is beneficial to democratic and scientific decision.
