THREE-DIMENSIONAL CORE HOLDER FOR PERFORMANCE EVALUATION OF OIL WELL CONFIGURATIONS

摘要

A three-dimensional core holder for performance evaluation of oil well- configurations comprising: a cover with plurality of holes and a body housing a core; a stand to tilt the core holder, an optional means for locking the core holder at a given inclination, wherein the body comprises of multi-holed side-faces and a bottom-face with the cover and side-faces of the core holder mutually perpendicular or optionally at an angle with each other, the number of holes on the cover and the side-faces varying from 1 to n=(L-s)/(s+d), wherein L is the length of the cover/side-face, s is spacing between two consecutive holes and d is the diameter of the holes, the number of rows on the cover and the side-faces varying from 1 to m = (W-p)/(p+d), wherein W is the width of the cover/side-face, and p is the spacing between two consecutive rows, the rows being parallel or staggered; wherein the holes being equipped with selective connecting and disconnecting means interconnected to form a manifold with options to remove the entire manifold for a given row to function as a conduit for injecting and / or ejecting fluids from one or more holes along a given row and introducing sealant fluid and venting gases, wherein pressure measuring devices can be fitted in the holes on the body faces and the cover; thereby facilitating saturation of the core, providing means for selective placement of injection and production wells and permitting pressure measurements and sealing the core and the drainage of the sealant.
