Basing on the present situation of Huqing oilfield ,aiming at
the question of the injectivity and pressure of separated layer is
difficult to definitely describe ,we developed the testing string to
enroll the injectivity curve and the starting pressure. Thus we can
discern the working affair of every layer , search the potentiality
and make the corresponding action , really realize the most
beneficial result to the reservoir bed. The paper introduces the
testing string ,the structure ,working princuple ,field test and the
achieved recognization.
