Płuczki wiertnicze na osnowie oleju nazywane ogólnie olejowodyspersyjne są jednym z rodzajów płuczek, które mogą być wykorzystane do wiercenia otworów prawie w każdych warunkach geologicznych. Podstawowym składnikiem pierwszych płuczek olejowo-dyspersyjnych była ropa oraz olej napędowy, które ze względu na ochronę środowiska przyrodniczego, zastąpiono związkami chemicznymi tzw. olejami syntetycznymi...
This presentation discusses results of field use of glycol-potassium drilling mud developed in Polish Oil and Gas Institute. These muds may be based on freshwater or saturated NaCl brine, with or without bentonite addition. Glycol-potassium drilling mud containing bentonite was used for drilling in Rhaetic and Keiper formations. This mud was later converted into NaCl saturated mud for further drilling...
This presentation discusses the possibility of inhibitive drilling muds formulation with potassium salts other than KCl. In Polish Oil and Gas Institute laboratory, tests were conducted on potassium polymer muds in which KCl was replaced by inorganic and organic potassium salts free of CI ions. Partial elimination of CI ion in muds is dictated by need of limiting the degree of environmental damage.
