A droplet of the crude oil is suspended between two parallel plates of quartz or calcite inside a simulated formation water bath at reservoir temperature and sometimes at reservoir pressure.
The lower the permeability and the smaller the pore-throat radius as well as the lower the reservoir pressure, the easier the formation of water locking damage, and it is difficult to be removed.
The characteristics and formation mechanism of coalbed methane reservoir pressure in Henan
Under given reservoir pressure, application of this method only requires production rate and flowing bottom-hole Pressure of gas well in a work system.
The impact of unbalanced reservoir pressure on lateral well deliverability
The results will provide decision basis for determining reasonable preserved oil reservoir pressure level, reasonable liquid? producing capacity and for conversing of production way in time.
The rule of reservoir pressure distribution and bottom hole flowing pressure alteration of a periodic trial-produce well in infinity subterranean formation.
