常見(jiàn)例句雙語(yǔ)例句Tight gas wells are generally characterized by low porosity, low permeability and high water saturation.致密氣井普遍具有低孔、低滲、高含水飽和度的特點(diǎn)。Correlations of reservoir properties wtih sedimentary and diagenetic facies are of great importance to the exploration and development of tight gas-bearing formations.四種成巖相組成了四種不同的儲(chǔ)層類型，儲(chǔ)層性質(zhì)的對(duì)比分析對(duì)識(shí)別致密氣層中的油氣產(chǎn)層具有重要意義。For low-permeability and tight gas reservoir, major factors of causing damage are water retention effect, stress sensitivity, water sensitivity, drilling operation inadequacy.水鎖效應(yīng)、應(yīng)力敏感、水敏性、鉆井施工作業(yè)不適當(dāng)是低滲致密氣層損害的主要因素。原聲例句These are gas-tight feedthroughs.這些是封閉的的引線。麻省理工公開課 - 固態(tài)化學(xué)導(dǎo)論課程節(jié)選權(quán)威例句The Energy Information Administration (EIA) puts it at around 37tcm of recoverable reserves, two-thirds of which is shale gas and the rest tight gas and coal-bed methane.ECONOMIST: Shale gas is giving a big boost to America’s economyHydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).FORBES: The Fracking Solution Is A Good Cement JobFracking, of course, is the controversial method by which producers extract tight oil and gas — a process that uses a concoction of water, sand and chemicals to break those deposits free from the rocks where they rest a mile beneath the ground.FORBES: California's Clash: Shale Oil or Green Energy 返回 tight gas
