Abstract

Determination of uniaxial compressive strength (UCS) of intact rock is an important mechanical parameter required for many engineering projects. In some engineering projects for example well drilling for production petroleum because of more deep well exist limitation for obtain rock core sample and determination UCS. On the other hand determination this parameter is essential in order to analysis well wall stability and wells development program. Because of this, the idea of using DRILLING CUTTINGs is proposed for determination UCS. In this paper in order to develop relationship between UCS and single compressive strength (SCS) were used from 7 block sample microcrystalline limestone from Asmari formation outcrops. Then UCS test was performed and was determined uniaxial compressive strength. Next these samples were crushed and were prepared 420 single particles. Then SCS for each particle is determined. Since shape of particles effect on particle strength therefore shape of particles has been modified and total particles that used for determination SCS was spherical. In order to study effect size of particle, particles with diameters 2, 3 and 4 millimeter is prepared and determined SCS for each particles. With increase diameter of particle, increase SCS. In order to eliminate effect of size particles is defined variable size and strength and is proposed chart between them. Coefficient of correlation between SCS and UCS is more than 0.91 that present exist good correlation between them.
