From the study of casing stress and strain in steam in jection wells,two me- thods of calculation are proposed,one for wells transformed for injection from production with or without cemented casings,and the other for calculation of the strength of pre-stressed casings in medium-deep wells.It is pointed out that when oil or gas wells are changed into steam injection wells,reliable measures for heat insulation must be taken and casing strength should be checked with heat intensity and heat conductivity...
Fracturing fluid is one of the most important elements for ensuring successful fracture operations. It must be viscous enough and capable of carrying sands deep into the fractures created in the reservoirs. With the fullest exploitation of the power of fracturing units, fracturing fluids should be used with the minimum damage to the reservoirs to achieve the maximum benefit. Wide differences of geological and physicochemical properties exist between reservoirs of different permeability. Application of...
