| titleOfInvention | Method of underground reservoir zone processing and media used therein |
| abstract | FIELD: mining. n SUBSTANCE: invention relates to drilling and well servicing fluids. Method of underground formation zone processing, opened by drilling well, involves use of oily cross-linking liquid composition containing oily liquid, suspending agent, which is clay or fill-silicate material, surfactant and boron-containing cross-linking agent, wherein oily liquid is hydrocarbon oil with flash point of 70–300 °C and contains 0.1 % of aromatic hydrocarbons maximum weight, selected from benzene, toluene, ethylbenzene and m-, o- and p-xylenes (BTEX) and alkyl substituted benzene components, production of formation treatment liquid consisting of water, gelling agent and oily cross-linking liquid composition, and introduction of said fluid for formation treatment in zone inside drilling well opening underground reservoir, oily cross-linking liquid composition contains from 0 to less than 5 ppb of benzene, from 0 to less than 1,000 ppb of toluene, from 0 to less than 700 ppb of ethylbenzene, and from 0 to less than 10,000 ppb of xylene, and from 0 to less than 1,000 ppb of alkyl substituted benzene components, including C2 and C3-benzenes, determined using EPA SW 8260 test method. Oily cross-linking liquid composition for underground wells servicing, containing: oily liquid representing hydrotreated hydrocarbon, boron-containing cross-linking agent with range of solubility in water from 0.1 kg/m 3 to 10 kg/m 3 at 22 °C and suspending agent, which is clay or fill-silicate material, where oily cross-linking liquid composition contains from 0 to less than 5 ppb of benzene, from 0 to less than 1,000 ppb of toluene, from 0 to less than 700 ppb of ethylbenzene and from 0 to less than 10,000 ppb of xylene, which are determined using EPA SW 8260 test method. Invention is developed in depending points of the formula. n EFFECT: increasing safety at maintaining of used hydrocarbon compositions utility during operation of deposits. n 24 cl, 1 dwg, 2 tbl, 1 ex |
