Abstract

Abstract:

The new-type fractured-vuggy carbonate reservoirs in the Tarim Basin feature rapid decline in production， low oil recovery and low producing/proved reserve ratio in oilfield development. The study discusses in-depth the geological characteristics and challenges faced in oilfield development in the fractured-vuggy carbonate reservoirs of Tahe and Shunbei oilfields， Sinopec， and systematically summarizes the technical progress Sinopec has made in reservoir characterization， oilfield development， production capacity construction and EOR. Meanwhile， suggestions on the future technology researches are put forward targeting different stages of oilfield development. The fractured-vuggy carbonate reservoirs having undergone multiple stages of tectonic movement， karstification and hydrocarbon charging are characterized by strong heterogeneity and complex oil， gas and water distribution， which bring multiple challenges to reservoir characterization， geological modeling， reserve evaluation， economic production capacity construction， water and gas injection， drilling engineering， acid fracturing， gas lifting and so on. After 20-year development practice， Sinopec Northwest oilfield has developed technologies for volume characterization， fine fault interpretation， karst system characterization based on geophysics， for geological modeling under karst facies constraint， and for targeted acid fracturing and enhancing oil recovery via water/gas injection. To achieve efficient development of Shunbei oilfield， it is necessary to study hydrocarbon accumulation characteristics based on fault analysis， facies-constrained geological modeling based on geophysical analysis， fluid phase behaviors and oil properties at high pressure， composition numerical simulation of reservoirs， coupling of reservoir geomechanics and numerical reservoir simulation， integrated simulation of reservoir and gas lifting， optimization of well location and drilling trajectory， and so on. To achieve the goal of greatly improving oil recovery in Tahe oilfield， it is necessary to further carry out researches on fracture-vug architecture description， karst genetic system， producing reserve estimation， mechanism and law of water/gas injection， network simulation with fracture， vug and well as nodes， and dynamic monitoring system.

Key words: reservoir characterization, geological modeling, enhanced oil recovery （EOR）, fractured-vuggy reservoir, Tahe oilfield, Shunbei oil and gas field, Tarim Basin
