Analysis of reservoir damage factors of water injection wells in ultra-low permeability oilfield
With the gradual improvement of people's quality of life,the demand for oil and gas is increasing,and conventional reservoir exploitation has entered the middle and late stage.The effective development of oil and gas resources in low permeability reservoirs is of great significance to the sustainable and stable development of petroleum industry in the future.Due to the problems of insufficient natural energy,poor water injection effect and uneven water injection in low permeability reservoirs,it is difficult to establish an effective drive system between oil and water wells,and it is difficult to ensure stable productivity for developed reservoirs,which has caused irreversible damage to the formation in the long run.Therefore,we should pay full attention to this kind of reservoirs,actively use acid plugging removal,surfactant flooding and even fracturing to solve the problem of formation damage in the development process,and improve the effective utilization rate of the reservoir.
