It is useful to know the critical subsidence pressures of deep well pipes by pipe manufacturers and users.
The geological units and structures show different characters as you go deep into the soil and the problems that may be encountered in the wells are different. Under normal conditions, vertical stresses increase with depth and are greater than horizontal stresses. But; Tectonic stresses, Geological structural changes, Structure of faults and folds, Temperature of the environment, Discontinuity of the layers events such as increase the horizontal stresses and in some cases the horizontal stresses can be greater than the vertical stresses. When choosing a well pipe, especially horizontal stresses should be known and pipe selection should be made accordingly.Show More
