SYSTEMS FOR TREATMENT OF UNDERGROUND BED WITH CIRCULATING HEAT TRANSFER FLUID |
摘要 |
FIELD: oil-and-gas industry.SUBSTANCE: set of inventions relates to extraction of products from underground beds. Proposed method of underground bed heating comprises heat feed from multiple heaters to one section of underground bed by heat carrier fluid circulation via at least one pipeline in at least one heater. Note here that a part of said pipeline of said heater can displace relative to well mouth with appropriate heater using at least one or more sliding seals in said well mouth to compensate for pipeline thermal expansion.EFFECT: higher efficiency of bed heating.19 cl, 1 tbl, 24 dwg |
