Study of the possibility of operating wells with intercolumn pressures

The article considers the issues of the possibility (impossibility) of operating wells in gas condensate fields with interannular pressures. The existing initial and regulatory information on the results of technical operation of wells has been studied and systematized, the requirements for ensuring industrial safety during operation of hazardous production facilities, protection of subsoil and the environment have been analyzed. The current state of operation of wells with interannular manifestations has been characterized and the problems arising in this case have been considered. The issues of identifying interannular manifestations in wells and their diagnostics have been considered, the safety level of operation of wells with interannular manifestations has been assessed. The paper presents the results of calculating the integral quantitative hazard assessment of an interannular manifestation, which is characterized by the hazard coefficient and its limit values have been determined. The definition of vulnerability, which is the property of well elements to lose the ability to perform specified functions, and an assessment of the safety of wells with interannular manifestations based on an assessment of the degree of hazard of interannular manifestations and the degree of vulnerability of the well and environmental objects have been given. The conditions under which a well can be operated with interannular pressures have been determined. Keywords: well; pressure; annular space; manifestations; risks; vulnerability.
