单词	borehole
释义	boreholebore‧hole /ˈbɔːhəʊl $ ˈbɔːrhoʊl/ noun [countable] Examples EXAMPLES FROM THE CORPUS An inventory of boreholes is to be compiled and a survey of dug wells will be made. But although test boreholes were successfully sunk at Altnabreac in Caithness in November 1975, the programme quickly ran into opposition elsewhere. Geological maps have been digitised together with the lithology and stratigraphy derived from over 1250 boreholes and geophysical logs from over 70 boreholes. If we drill a borehole into the aquifer the groundwater will be under sufficient pressure to overflow from the borehole. No gas fields occur in the Bramsche and Vlotho Massifs, although in the past many boreholes have been drilled there. Resistivity methods have been developed for investigating fracturing in boreholes. They are large, and hence the chances of recovering complete specimens from all boreholes is relatively low. Welds split because of continual use, and poorly constructed boreholes let sand and grit into the well water. word sets WORD SETS► Civil aqueduct, nounbore, verbbore, nounborehole, nouncanalize, verbcivil engineering, nounculvert, noundam, noundam, verbdesalination, noundredge, verbdyke, nounpile, nounpile driver, nounpneumatic drill, nounpontoon, nounpontoon bridge, nounS-bend, nounsewer, nounsewerage, nounsteam shovel, nounstructural engineer, nounsump, nounsurveyor, nounwater main, nounwater tower, nounwaterworks, noun Collocations COLLOCATIONS FROM THE CORPUSVERB► drill · If we drill a borehole into the aquifer the groundwater will be under sufficient pressure to overflow from the borehole. a deep hole made using special equipment, especially in order to get water or oil out of the ground
