| Abstract: | Low pressure oil well can easily be damaged because of the leakage of incoming well fluid in the course of the workover job and its productivity may be reduced.Aimed at the condiction,the article analyzes entirely the damage reasons of the incoming well fluid to the reservoir and reservoir protection techniques suited for low pressure oil well workover iob are perfected from optimizing incoming well fluid system,inducing the leakage and preventing secondary damage aspect.The healing time of the low pressure oil well productivity is shorted fourteen days than ever and the remarkable economic benefits are obtained through field application of the reservoir protection techniques. |
