The fractured-vuggy carbonate reservoir is one of the main types of oil and gas reservoirs in Tarim Basin, which has great potential and broad prospect. In recent years, Sinopec Northwest Oilfield Company has continued the exploration and development for them, and has made many breakthroughs in the researches of basic geological theory of carbonate rock, seismic identification technology of fracture cavity body, and high-efficiency development engineering technology. And it has established a series of relatively perfect geological and reservoir engineering methods and technologies for carbonate reservoirs. It has realized the continuous increase of storage and production and efficient development of carbonate reservoir in Tahe oilfield, showing a good prospect of exploration and development, and also providing reference for the exploration and development of similar reservoirs at home and abroad. However, how to develop carbonate fracture-cavity reservoir sustainably also faces the problems and challenges such as theoretical innovation and technological breakthrough. It is urgent to tackle the key problems and make breakthroughs in fracture-cavity structure description, quantitative characterization of remaining oil, utilization of reserves around wells, and heavy oil recovery, so as to continuously promote high-efficiency and high-quality development of carbonate fracture-cavity reservoirs.

Key words: Tahe Oilfield, Ordovician, carbonate rock, fractured-vuggy reservoir, identification of fracture and vug, reservoir geological method, engineering technology
