Abstract

The Triassic Yanchang Formation is an important reservoir in Changqing Oilfield, with obvious starting pressure phenomenon. After the discussion on the cause, it is believed that the phenomenon was resulted from multi- factors. The analysis testing is carried out in Houshi area, and the result shows that the Triassic Yanchang Formation in Houshi area has obvious starting pressure, with a starting pressure gradient of 0.327MPa/m.
