Annotation:
The authors of the article analyze studies of gas condensate wells of the Orenburg oil and gas condensate field using the pressure recovery curve method and a full range of well geophysical survey data. A method is proposed to reduce the idle time of measuring wellhead static and reservoir pressures for a number of gas condensate wells of the Orenburg oil and gas condensate field. The procedure of conducting gas hydrodynamic studies of gas condensate wells of the Orenburg oil and gas condensate field is established by the organization standard STO 05-03-2014. At present, according to the organization standard, the estimated time of recording the pressure recovery curve in wells of the Orenburg oil and gas condensate field when penetrating the deposits of the main reservoir, depends on the well flow rate and does not take into account the objects of opening. The aim of the work is to reduce the idle time for measuring wellhead static and reservoir pressures for a number of wells of the Orenburg oil and gas condensate field and, as a consequence, to reduce the necessary reductions in the production of hydrocarbon raw materials. Reducing the time for measuring reservoir pressure is possible by taking into account the well characteristics (filtration and capacity properties).
