GAS TEST TECHNIQUE FOR SUPER-DEEP WELL YB1-C1 WITH HTHP AND HIGH SOUR

The YB1-C1 Well was finished at the depth of 7427.23m,bottomhole temperature 0f 153.5℃ and bottomhole pressure of 86MPa.Based on the analysis of test difficulties in the well,the combining technique on test,perforation and acid fracturing,and solid free kill fluid were used for the gas test of YB1-C1 Well.This paper presented the test processes and the results of test in detail,and the APR test model suited for YB1-C1 well with HTHP and high sour was formed.The research provided reference for the tests of similar well in the future.
