Method for creation of a damage within the porous area of the rock formation core, formed during the operations of the hydraulic fracturing by means of foamed fracturing fluids and the measuring system for the damage of the porous area of the core by the fracturing fluids

摘要

method of manufacture of the pore space core rock formation, resulting in hydraulic fracturing treatments spienionymi fluids szczelinuju0105cymi is suchthat is the preparation of cylindrical rock samples zu0142ou017cowej to test, and then determine their permeability and porositythen in the first stage is placed a rock sample zu0142ou017cowej in steel chamber filter and moving termostatowanie chamber together with the core to a temperature representative zu0142ou017cowe conditions.and then saturates to cylindrical rock samples zu0142ou017cowych brine and determines the temperature and pressure which represents the flight conditions zu0142ou017cowe system in the measurement system.followed by filling the tank and tubes reometru liquid szczelinuju0105cym and define its parameters reologicznych,and then transmits the fluid through the sample and measure the filtration, and then in the second stage, placed a newpreviously prepared the sample in the steel chamber filter and moving termostatowanie chamber together with the core to a temperature representative zu0142ou017cowe conditions.and then saturates to cylindrical rock samples zu0142ou017cowych brine and determines the temperature and pressure which represents the flight conditions zu0142ou017cowe system in the measurement system.followed by filling the tank liquid szczelinuju0105cym,then the measurement system reometru and foaming it by adding the nitrogen or / and carbon dioxide and the determination of the parameters reologicznych fluid.and then transmits the fluid sample and is measured by filtration.and in the third stage, compares the results obtained filtration and shall assess the effects of a fluid expansible or niespienionych on rock zu0142ou017cowu0105 after surgery hydraulic shoot itsubsidies and determine the degree of damage to the pore space.the measurement system for the damage of the pore core by fluids szczelinuju0105ce is suchthe filter chamber (3) equipped with a handle (5) for fixing the core (7) through the seal (6) and the chamber (4) together with the outside liquid, and containing a heating system (8),reometr pipe (1) is connected with the generator set and the hplc pump (2).
