1. At carrying out of processings both extracting, and forcing chinks compositions are traditionally applied soljanokislotnye (SKO) and glinokislotnye (state credit obligations). In a layer there is a reaction zakachannyh acid baths to clay minerals and quartz therefore the gel deposit which blocks channels of a filtration for oil is formed.

For reduction of these negative consequences at layer processings in acid add various superficially active materials (HAVING fallen). However, their application does not allow to exclude completely breaking and its full extraction from a layer, especially at sheet temperatures above 50 ° With and high glinizatsii a layer, for example, in the conditions of deposits of Western Siberia.

2. An acid composition "HIMEKO ТК-2" for terrigennyh

Collectors, possesses time-lagged reaction rate, in which result

93 there is a gradual allocation of fluorhydric acid and organic salts-buffers which being hydrolyzed evolve hydrions and constantly support rn before full neutralisation of fluorhydric acid, interfering with fallout of deposits.
