Waterflooding process modeling using by weierstrass elliptic functions
Kasatkin A.Y.
Abstract
Waterflooding is one among several second oil recovery methods and it produces a high oil recovery rates by injection water into the oil keeping formation. Increasing waterflooding efficiency using by optimal well location scheme is an actual task. To achieve the corresponding goal we propose a program tool for well location schemes compare, both of by quantitative and qualitative characteristics. The program realization based on the oil keeping reservoir pattern represented a homogeneous formation with fixed thickness and infinite borders covering by dual periodical lattice: it includes production and injection wells into her cells. Also this lattice requires dual periodical property from the speed function defined on her cells. So we had used modified Weierstrass dzeta-function to describe oil-water filtering process in modeling reservoir.

Hardenability caclulation for 14XH3MA, 15H3MA, 19XГМА bit steels produced by OJSC «Izhestal»
Pugacheva T.M., Borovikova Y.V., Miheev D.A.
Abstract
This paper contains comparative analysis of hardenability of end quenching test and values calculated by chemical composition in accordance with ASTM A 255. Hardenability estimates by hardness on 6.5 mm and 30 mm depth from standard sample surface. Analytic formulas (ASTM A 255) are shown to be not applicable for these steels. Analytic equations «Hardness - Chemical composition» which predict hardness on 6.5 and 30 mm depth from standard sample surface with quite high accuracy were determined by regression analysis. These equations can be used for hardenability analysis of these steels if the input control of rolled metal quality instead of currently used hard gradient quenching method.

Abstract
Semicircular profile cut radius influence on cylindrical solid and hollow specimens made of steel 20 with 25 mm diameter endurance limit has been examined under outstripping superficial plastic deforming. It’s established that the endurance limit decreases with the increase of cut radius from 0,3mm to 1mm under the same type of hardening. It should be increase the specimens hardened superficial lay thickness under outstripping superficial plastic deforming for hardening effect conservation.
