摘要

Pore pressure, breakdown pressure and collapsing pressure are the bases of determining the casing programmed, drilling fluid density and cementing and completion plan, and are important in the design of drilling engineering. Analysis was made on prediction technique of formation pressure in volcanic rocks, and for the first time, the advanced rock mechanics theory abroad was put into volcanic rocks in Qingshen gas field.3 pressure prediction models were made, new correction methods were put forward according to these models and the characteristics of volcanic rocks in Qingshen gas field;3 pieces of pressure prediction software were worded out, and the precision met the construction requests, it provides the reference for the design of drilling engineering in Daqing area.
