| 释义 | borehole noun[ C ] uk /ˈbɔː.həʊl/ us /ˈbɔːr.hoʊl/ a deep hole made in the ground when looking for oil, gas, or water: （为寻找石油、天然气或水而钻的）钻井，钻孔 We must sink a borehole so that people will have water.为了让大家有水吃，我们必须掘井。 They obtained information about the rock by drilling boreholes.他们通过钻孔获知了关于岩石的情况。 Engineering - mining & quarrying anti-mine banksman beneficiation biomining coal coal miner coal mining coalface excavator extract mineral mining OPEC petrodollar pit pithead slag heap strip mining unworked workings Examples of boreholeborehole Units 2 and 3 have been grouped since they cannot be distinguished from one another in every borehole. The accuracy of the stripping model depends on the available borehole, seismic and density data. The most obvious application of palaeomagnetism to oilfield investigation, namely borehole to borehole correlation, actually proves to be the least efficacious. Of particular note are the new borehole data from the lowermost part of the formation which does not crop out in the type area. Although the quality of the available information is uneven, an accurate analysis and filtering of the borehole logs provides a useful database of subsoil geology. This provides the basis for in situ subsurface analysis of the geology, mineralogy and organic chemistry of the borehole environment. Short final chapters on radiometric methods and drilling and borehole logging complete the book. In a typical well with an inclined borehole, the heavy steel casing lies eccentrically towards the lower side of the hole. In 1996, a community water system served almost the whole population of the town, using groundwater from a single borehole as one source. A borehole camera system for imaging the deep interior of ice sheets. It is not yet clear whether it could be deployed by the mole without increasing the complexity of the mole's depth profile and corrupting the pristine borehole environment. Sharp density changes across the linear inversion structures will not have been adequately sampled by the borehole coverage and are therefore only estimated in the density grids. Water sources include a typical lowland river, impoundment reservoir supply and typical deep borehole supplies. Geometry and facies of the sedimentary infill at its central sector have now been characterized from compiled borehole data, which allows discussions of how the evolutionary model is constrained. These examples are from corpora and from sources on the web.
