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.
