METHOD FOR PREVENTING CARRYING OF SAND OUT OF WELL

摘要

FIELD: oil and gas production industry. SUBSTANCE: according to method, injected into cavernous space of bottom-hole zone of well is gravel mixture. Mixture is produced from several size fractions of gravel beginning with smallest size fraction to largest fraction which are increasing in size towards bore-hole of well. On completion of gravel filling, injected is permeable plugging compound with particle size of soluble components not larger than size of gravel particles of largest fraction. EFFECT: higher efficiency. 1 cl
