| الوصف: | Differential sticking is defined as stuck pipe caused by the differential pressure forces from an overbalanced mud column acting on the drillstring against filter cake deposited on a permeable formation. It is influenced by drilling fluid properties and characteristics of rock formations and has major impact on drilling efficiency and well costs respectively. Differential sticking tendency of two drilling fluids were determined in laboratory using sticking tester as well as influence of lubricant and increase of solids content on fluid properties. Results of the testing are presented in the paper. Diferencijalni prihvat definira se kao prihvat bušaćih alatki prouzročen diferencijalnim tlakom koji se javlja uslijed djelovanja stupca isplake na niz bušaćih alatki, a uzrokuje "ljepljenje" bušaćih alatki za isplačni oblog kojim su obložene stijenke kanala bušotine u području propusnih naslaga. Uvjetovan je svojstvima bušotinskih fluida i karakteristikama naslaga stijena kroz koje se buši i ima veliki utjecaj na učinkovitost bušenja i troškove izrade bušotine.U laboratoriju je pomoću instrumenta za određivanje koeficijenta ljepljivosti ispitana sklonost odabranih fluida diferencijalnom prihvatu odnosno utjecaj količine čvrstih čestica i podmazivača na svojstva fluida i koeficijent ljepljivosti. Rezultati ispitivanja prikazani su u radu. |
