ABSTRACT: X oilfield is located in the Western
Bohai Sea. During the water injection development process, the oil well
productivity continued to decline. The effect of water injection and oil
increase is poor. This time, by analyzing the sensitivity of the reservoir, the
damage mode of the reservoir is analyzed, the reasons for the poor water
injection effect are obtained, because of strong water sensitivity, medium to
strong stress sensitivity, and the corresponding measures and suggestions are
put forward, such as greater than 4500 mg/l of the salinity of injected water,
timely supplement formation energy. Provide basis for the development of
similar oil fields.
