摘要In order to economically and effectively develop shale gas in China, Sinopec introduced foreign technologies and integrated them with available domestic technologies and self-developed tools according to geological characteristics and complicated mountainous geomorphology in marine shale plays of southern China. A technology series composed of innovated theories concerning geological characterization during drilling, new generation of PDC bits, friction-reducing tools, low-cost oil-based drilling fluid system, high-efficient washing fluid and elastic mud systems, integrated drilling engineering design, long lateral cementing, modified well factory drilling method and etc., was developed to fulfill fast and optimized drilling for shale gas wells. The application of the technology series in about 251 wells of Fuling gas field, Chongqing City, southwestern China, showed positive results: mechanical rotating speed increased by 191%, drilling duration reduced by 53%, and quality passing percent 100%.
