Arranged on the wedge body is an elastic casing which is pushed over a tubular sliding wedge secured at the end and in the process is widened in such a way that it bears tightly against the borehole wall. This is achieved by the feed tube moving into the wedge body and displacing the ...
In case of open and sealed pores on borehole wall were obtained enough simple analytical expressions for this ratio.doi:10.1142/S0218396X10004085Boris D.plyshchenkovAnatoly A.nikitinWorld Scientific Publishing CompanyJournal of Computational Acoustics...
When impregnation materials are injected, an impregnation material supply channel to the front hole 24 and the inside of the pin 33 in cut off to the contrary, the side holes 12 and 24 are together connected, and the impregnation materials are jetted toward a hole wall. 展开 ...
electrical discharge drilling (EDD), including a recast layer and microcracks on the hole wall. Therefore, abrasive water flow polishing (AWFP) of a superalloy inclined hole array machined via EDD was investigated in this study. Two types of specimens were designed: a hole array of identical ...
PURPOSE:A water sealing means of a charging hole comprising a water sealing groove, a water draining groove fixed along the outer side of the sealing groove with a partition wall therebetween, a water-supply pipe and a scatter-prevention cover, thereby unnecessitating the labor- and time-consumi...
Stress orientations from borehole wall fractures with examples from Colorado, east Texas, and northern Canada Azimuthally aligned breakouts in oil wells are explained as shear fractures in the zone of amplified stress difference near the borehole, in a stress field... DI Gough,JS Bell - 《Can...
Primordial black holes (PBH), if survive to the present time, can be a fraction, or even the dominant form of dark matter of the Universe. If PBH evaporate before the present time, rare forms of dark matter like superweakly interacting or supermassive particles can be produced in the course...
The drilling cuttings migrate and accumulate over time between the borehole wall and SMH drill pipe, which increases their compressive forces and induces increases in the mass and diameter of those entering into the sieve holes. The sieve hole diameter and depth are critical factors impacting the ...
