Abstract

Vynález se týká způsobu regulace vlastností a stavu vrtného roztoku při vrtání a může ho být použito při těžbě ropy a plynu, v geologickém průzkumu a rovněž při chemickém zpracování ropy,v hornictví, strojírenství a v jiných odvětvích národního hospodářství. Cílem vynálezu je zvýšení kvality vrtného roztoku,snížení ztrát a rozšíření oblasti využití způsobu a rovněž snížení možnosti vzniku havárie při vrtání. Novost způsobu spočívá v tom, že v průběhu vrtání se sleduje hodnota redox-potenciálu cirkulujícího roztoku a při odchylce od rovnovážného stavu se vrtný roztok zpracovává v zóně jedné z elektrod stejnosměrným proudem až do dosažení původní hodnoty redox-potenciálu,které eliminuje destabilizační působení vrtných zplodin tak, že zabraňuje destabilizaci.The invention relates to a method for regulating the properties and state of drilling fluid during drilling and can be used in oil and gas extraction, geological exploration and also in chemical processing of oil, mining, engineering and other sectors of the national economy. The aim of the invention is to increase the quality of the drilling fluid, reduce losses and expand the area of application of the method and also reduce the possibility of an accident during drilling. The novelty of the method lies in the fact that during drilling the value of the redox potential of the circulating solution is monitored and, in the event of a deviation from the equilibrium state, the drilling fluid is processed in the zone of one of the electrodes with a direct current until the original value of the redox potential is reached, which eliminates the destabilizing effect of drilling waste products in such a way as to prevent destabilization.

OBJECT OF THE INVENTION 217 153 A method of controlling the properties of a drilling solution in process circulation by treating it and providing a stable physico-chemical property of the solution to compensate for the destabilizing effect of drilling products and directing the stabilizing effect on the solution properties, characterized in that in order to increase the range of controllable flow parameters the destabilizing effect is monitored by the redox potential of the circulating drilling solution and the solution is electrolytically processed when the equilibrium is changed. Recognized by the invention on the basis of the results of expertise made by the USSR State Inventions and Discoveries Committee, Moscow, SU. 1 drawing
