Correlation of criteria for perforation and pore plugging by particles
Iscan, A. Gurkan; Civan, Faruk (Begell House, 2006-01-01)
Particles at high concentrations and unfavorable flow conditions may plug pores and perforations by bridging across during various well operations including particle-containing water injections and workover activities. This study presents an experimental determination of the conditions leading to plugging and the criteria for effective plugging conditions. The charts of the perforation or pore size to particle size ratio versus the particle Reynolds number are shown to determine the conditions leading to pe...
CORRELATION OF ROCK PROPERTIES AND CUTTING RESISTANCES IN ASSESSMENT OF DIGGABILITY WITH BUCKET-WHEEL EXCAVATORS
BOLUKBASI, N; KONCAGUL, O; PASAMEHMETOGLU, AG (1991-09-01)
A study has been undertaken to establish relationships between the O&K wedge test cutting resistances, F(A), F(L) and F(LS), and the geotechnical parameters of rock materials in the context of bucket-wheel excavator operation. Prediction equations were formed to estimate the cutting resistance from the geotechnical parameters by multiple regression analysis and the cone indenter index, uniaxial compressive strength and Shore hardness parameters have been found to be the most significant predictors.
CORRELATION OF MICROSTRUCTURE AND FAILURE INITIATING SITES IN AN AISI M2 HIGH-SPEED STEEL USING VICKERS INDENTATION
Ögel, Bilgehan (1990-01-01)
In this study, the relation of crack initiation and propagation to microstructure was shown in an AISI M2 high-speed steel using Vickers hardness indentation. Observations were carried out on the cracks generated from the corners of the square pyramid indentation in both the as-quenched, the quenched and tempered specimens. It is shown that cracks are nucleated from the corners of the indentation by either cleavage of the carbide or by decohesion between the carbide and the matrix, depending on the size o...
