Organization of control over the condition of wells during working of oil fields of West Siberia

Experience is generalized of conducting studies to monitor the technical condition of wells in West Siberia at the stage of working the fields. Results are indicated of the effect of perforation on the casing and recommendations are made for optimization of the perforation density. The possibility is examined of using gamma-logging to diagnose the salt-depositing based on the manifestation of radiogeochemical effect. Main reasons were established for the lack of sealing of the strings and the transpipe circulation of water and gas. A plan was developed for determining the sources of flooding and gas content. High efficiency is shown of the thermometry, neutron logging and method of isotopes for determination of the intervals of unsealing of the casings and overflow of water and gas. Questions are covered of studying the depositing of mechanical admixtures in the recovery, injection wells and objects of the system for collection and preparation of oil.
