It is necessary to measure stratum pressure in the process of developing oil field.

Reasonable value of the reservoir pressure and bottomhole flowing pressure of oil well at the stage of Super-high water cut for Lamadian Oilfield;

It is found that the stress difference between the minimum in-situ stress and reservoir pressure is linearly correlated with vertical depth and their correlation is extremely hi.

However,with reservoir pressure drawdown and water-cut increase during the production,the sand production became more and more serious.

Characteristics of formation pressure and its influences on reservoirs of the fourth member of the Shahejie Formation in Sheng-tuo area of Dongying Depression;

A method for predicting formation pressure using production data for confined gas reservoir;

A method for calculating formation pressure in low permeable fractured well using earlier well test data;

Contraposing the slow rapidity of closed-in pressure comeback,overtime of pore pressure test,great workload and high cost when carry through repeated off-take potential in low permeability gas field,on the basis of theory of gas reservoir engineering,the research concludes the simple method of calculation of present pore pressure,open flow potential and the position of well bore fluid level.

The pore pressure is one of the basic data during the whole process of oil exploration and production.
