چکیده
An effective drilling fluid removal is necessary to achieve an efficient cementing in oil and gas industry, i.e., it ideal that all the displaced by cement slurry. The displacement efficiency closely related stability development of displacing interface between slurry fluid. Thus, requires a validated theoretical model describe guide applications, especially for highly deviated wells. current studies suffer from lack experimental validation proposed models. In this study, interfacial eccentric annulus established. study conducted examine effects well inclination, eccentricity properties on verify model. found annulus, applicable wellbore with different inclination angles. results show that: gradually extends (i.e., length increased) increase inclination; effect became worse deviation angle under same injection replacement conditions. Increasing apparent viscosity beneficial improve interface. wells, certain casing can inhibit penetration wide gap low side which conducive maintaining

متن کاملA Mechanical Model and its Experimental Verification for a Water Injection String in a Highly Deviated Well
Water injection strings in highly deviated wells are subjected to complex forces on the string bore. In this work, a mechanical model is developed for these forces and for those on downhole tools. On the basis of this model, and taking account of the characteristics of the string in different working conditions, a temperature field model and a pressure field model are introduced, and a statical...

Experimental and Theoretical Study on the Ability of Microbial Fuel Cell for Electricity Generation
The present study aims at designing a promising Microbial Fuel Cell (MFC) to utilize wastewater in order to generate electricity. Two types of salt bridge have been used in MFC (KCl and NaCl). The maximum electricity generation with 1M KCl and NaCl has been 823 and 713 mV, respectively. Varied salt concentrations (0.5M, 1M, 2M, and 3M) of salt bridge in MFC have been analyzed with different fac...
