Production of high-temperature claydite from loams of the Vladimirovskoe Deposit

The possibility of producing high-temperature claydite on the basis of low-grade overburden rocks (loams) of the Vladimirovskoe Deposit is considered. The correcting additives are taken from industrial waste, namely, solar oil and chamotte-kaolin dust from electric filters of rotary kilns.Translated from Ogneupory, No. 4, pp. 26 – 28, April, 1996.     

Calculation of a three-dimensional flow of a viscous incompressible liquid in the neighborhood of a shallow well on a flat surface

A three-dimensional flow in the neighborhood of a shallow well on a plane was simulated numerically on the basis of a solution of the Reynolds equations written in curvilinear nonorthogonal coordinates and closed by a two-parametric dissipative model of turbulence.The work has been financed by the Russian Basic Research Foundation (Grant No. 94-02-04092 a).Civil Aviation Academy, St. Petersburg, Russia. Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 67, Nos. 5–6, pp. 373–378, November–December, 1994.     

Assessment of trunk-pipeline survivability taking into account residual welding stresses

A method to calculate pipeline survivability (operability of a part having cracks) taking into account residual welding stresses is proposed. This method allows one to determine the pipeline’s residual life, i.e., to make a conclusion whether the pipeline may be operated after ultrasonic testing detects cracklike defects of a certain size.     

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer

Analytical solution of a system of nonlinear measuring equations of a 12-pole microwave reflectometer was obtained. Criteria for selecting a true solution in the general case were developed and the analysis was conducted for a number of particular cases that may generate practical interest.     

高精度井口压力监测系统简介

新疆大多数气井井口压力高,用常规的试井工艺无法进行井下测试。采用井口压力监测系统可解决井口压力高、常规试井工艺无法实施的问题,节约高昂的井下测试费用,对油井实现无人值守实时监测,并实现远程数据传输。利用井口压力数据折算到地层中部的方法获得井下油气藏的数据。     

Influence of lead on the wear resistance of cast composites of the Fe-Cr-Cu-Ti-C system in sliding friction

The positive influence of lead (2.5%) on the original structure of a cast composite of the Fe-Cr-Cu-C-Ti system, its wear rate, friction coefficient, and the formation of secondary structures is established under the conditions of dry friction and friction with boundary lubrication. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 42, No. 6, pp. 73–80, November–December, 2006.
