METHOD AND EQUIPMENT FOR SEARCHING AND FORMATION OF HYDROCARBON DEPOSIT Russian patent published in 1998 - IPC

FIELD: oil and gas production industry. SUBSTANCE: according to method, subjected to heat treatment is bed containing hydrocarbons in solid, liquid or gaseous state which can be used in oil and gas production industry. Method is effected by heating of supposed oil bed by external heat sources controlled from day surface. To prevent Jamin effect in bed volume at stage of initial creation of deposit which hinders filtration of fluids to well in process of its testing for inflow, heat carrier is delivered to bed in the form of wave energy. Simultaneously installed on day surface above supposed productive area and in predetermined order ensuring heat covering of area are mechanical and electromagnetic wave generators. Boundaries of heated depth of bed, frequency of carrying sinusoidal signal of electromagnetic field, frequency of manipulated high-frequency filling electromagnetic field are regulated and selected in compliance with thickness and depth of bed and distribution of pores according to size. Inflow of heat and operating modes of generators are checked according to change of bed temperature. Process of bed heating and searching for created gas- and oil-water contacts is automated with taking consideration of aggravating factors. EFFECT: high efficiency. 21 cl, 26 dwg
