Abstract: 1. Method of treating in situ of hydrocarbon-containing formation and a method of preparing a hydrocarbon-containing fluid from formation, where the pressure and temperature are regulated in accordance with expression: P>=0.07*e wherein P is pressure (absolute, bar), T is temperature ( degree C), and A and B are preliminarily installed parameters, related to the faculty, compared with quantity, content and quality of received hydrocarbon fluids, and A is at least 5000, and B is at least 10. 2. Method according to claim 1, in which hydrocarbon containing formation contains kerogen, representing a coal or coal stone, or heavy hydrocarbons, representing bituminous sand. 3. Method according to claim 1 or 2, in which a heat source, providing conductive heating of the formation. 4. Method according to any of claims 1-3, in which hydrocarbons in formation are subjected to pyrolysis by heating at the temperature ranging from 250 degree C to 400 degree C, preferably, ranging from 260 degree C to 375 degree C. 5. Method according to any of claims 1-4, in which the pressure is at least 1.4 bar (140kPa), wherein if the pressure is 3.52 bar (352kPa), and pyrolysis is done at the temperature 301.7 degree C, the heating source to be used is different from that provides only high-frequency heating. 6. Method according to claim 1, in which the hydrocarbon pyrolysis is realized by regulating of the pressure and in presence of hydrogen at partial hydrogen pressure of at least 0.5 bar (50kPa), preferably, ranging from 1 bar (100kPa) to 10 bar (1000kPa), more preferably, from 5 bar (500kPa) to 7 bar (700kPa). 7. Method according to any of claims 1-3, in which A is 14000, and B is 25. 8. Method according to any of claims 1-6, in which A is 24146, and B is 43.349. 9. Method according to any of claims 1-6, in which A is 30864, and B is 50.676. 10. Method according to any of claims 1-6, in which A is 16947, and B is 33.603. 11. Method according to any of claims 1-6, in which A is 57379, and B is 83.145. 12. Method according to any of claims 1-6, in which A is 5492.8, and B is 14.234. 13. Method according to any of claims 1-6, in which A is 38360, and B is 60.531. 14. Method according to any of claims 1-6, in which A is 6613.1, and B is 16.364. 15. Method according to any of claims 1-6, in which A is 28554, and B is 47.084. 16. Method according to any of claims 1-6, in which A is 11118, and B is 23.156. 17. Method of synthesis gas production from hydrocarbon containing formation, treated by the method according to any of claims 1-16, in which at least one part of treated hydrocarbon containing formation is reacting with fluid, forming synthesis gas. 18. Method of producing hydrocarbons from synthesis gases, received according to claim 17, in which synthesis gases are transformed to hydrocarbons. 19. Method according to claim 18, in which synthesis gas is transformed in paraffins by a method of Fischer - Tropsche, and then paraffins are converted in the hydrocracker. 20. Method of producing the energy from synthesis gas according to 17, which is used in electric power installation. 21. Use of synthesis gas produced according to method of claims 17-20 in fuel element.
