A:正確B:錯(cuò)誤答案:錯(cuò)誤Whatkindofparameterweintroducedtocanceltheintegration?

A:ZfactorB:GasviscosityC:AveragepressureD:Realgaspseudopressure答案:AI參考:正確答案是D：Realgaspseudopressure。\n\n根據(jù)問題描述，需要引入一種參數(shù)來取消集成，而選項(xiàng)中只有D項(xiàng)“真實(shí)氣體偽壓力”符合要求，因?yàn)樗梢杂脕砻枋稣鎸?shí)氣體在容器中的流動(dòng)特性，從而可以取消集成。其他選項(xiàng)中，A項(xiàng)“Z因子”通常用于描述氣體的壓縮性，B項(xiàng)“氣體粘度”通常用于描述氣體流動(dòng)時(shí)的阻力，C項(xiàng)“平均壓力”通常用于描述氣體在不同區(qū)域的壓力分布情況。因此，正確答案是D。'Theplotofloggasflowrate,q(t),vs.tisastraightlinefor()decline.

A:harmonicB:exponentialC:noneoftheaboveD:hyperbolic答案:AI參考:正確答案是C：noneoftheabove（上述都不對(duì)）。\n題目中描述的是氣體的流量率q(t)與時(shí)間t的關(guān)系是一條直線，沒有給出任何下降的趨勢(shì)，因此選擇C。A、B、D選項(xiàng)都是與下降趨勢(shì)有關(guān)的描述，不符合題意。'InArps’empiricalrate/timedeclineequation,Diis().

A:declineexponentB:initialdeclinerateC:noneoftheaboveD:initialproductionrate答案:AI參考:正確答案是D:initialproductionrate。\nInArps的實(shí)驗(yàn)率/時(shí)間下降方程中，Di代表初始生產(chǎn)率。因此，答案為D。'Forx<(),Ei(x)canbeapproximatedwitha<0.6%errorbyEi(x)=ln(1.781x).

A:0.01B:0.001C:0.02D:0.002答案:AI參考:正確答案是【B:0.001】。\n\n題目中給出的公式是Ei(x)=ln(1.781x)，這個(gè)公式可以用來近似計(jì)算x以下的數(shù)值，誤差在0.6%以內(nèi)。因此，要選擇一個(gè)比x小的數(shù)值，使得誤差在0.6%以內(nèi)，所以答案為B：0.001。'Dynamicviscositydependsonpressure,temperatureand().

A:volumeB:gascompositionC:massD:boilingpoint答案:AI參考:正確選項(xiàng)是【B:gascomposition】。\n\n根據(jù)問題描述，動(dòng)態(tài)粘度取決于壓力、溫度和氣體成分。因此，選項(xiàng)B是正確答案。其他選項(xiàng)A、C、D與問題描述不符。'Thedry-gasreservoirmeansthatthereisnoliquidhydrocarbonforminthe()duringproduction.

A:ReserviorB:WellboreC:StoragetankD:Surfaceequipment答案:AI參考:正確選項(xiàng)是B:Wellbore。\n\n根據(jù)上下文，題目中的“dry-gasreservoir”指的是干氣儲(chǔ)層，意味著在生產(chǎn)過程中沒有液態(tài)烴的存在。因此，選項(xiàng)中與生產(chǎn)過程相關(guān)的只有“Wellbore”（井眼），所以B選項(xiàng)是正確答案。其他選項(xiàng)A（儲(chǔ)層）、C（儲(chǔ)存罐）和D（表面設(shè)備）都與生產(chǎn)過程中的實(shí)際情況不符。'Becauseofreservoir(),theencroachingwaterdoesnotsweepsomeportionsofthereservoireffectively.

A:faultsB:waterinfluxC:discontinuitiesD:heterogeneities答案:AI參考:正確答案是B:waterinflux。\n根據(jù)句子意思，由于水庫的水流入，侵入的洪水沒有有效地掃過水庫的一些部分，因此選項(xiàng)B“水流入”符合語境。選項(xiàng)A“faults”意為“斷層”，與句子意思不符；選項(xiàng)C“discontinuities”意為“不連續(xù)性”，也不符合語境；選項(xiàng)D“heterogeneities”意為“異質(zhì)性”，也與句子意思不符。因此，答案為B。'）Theconcentrationofdissolvedsolidsinwatercanbemeasuredwithseveraldifferentunits,including().

A:gramsNaclperliterB:gramsofsaltperliterC:weightpercentD:partspermillion答案:AI參考:正確選項(xiàng)是【D:partspermillion】。\n\n題目中提到“水中溶解物的濃度可以用幾個(gè)不同的單位來測(cè)量”，而選項(xiàng)D“partspermillion”（百萬分之一）是表示水中溶解物濃度的常用單位之一。其他選項(xiàng)中，A、B、C都與題目描述不符。因此，選項(xiàng)D是正確答案。'Whichofthefollowingformsdoesthedecline-curvehave?()

A:LinearB:harmonicC:ExponentialD:hyperbolic答案:AI參考:正確答案是C:Exponential。\n\n選項(xiàng)A和B是線性或正弦曲線，選項(xiàng)D是雙曲線或拋物線，都不是符合“下降曲線”特征的曲線。只有選項(xiàng)C，即指數(shù)曲線，在前期增長快速，后期速度減緩，呈現(xiàn)出下降的趨勢(shì)。所以答案為C。'Datausedtoestimatethegas-bearingreservoirporevolumeinclude,butarenotlimitedto().

A:fluidsampleinformationB:bottomholepressureC:welltestsD:welllogsE:coreanalyses答案:AI參考:正確選項(xiàng)為：A:fluidsampleinformationB:bottomholepressureC:welltests\n\n根據(jù)問題描述，用于估算含氣儲(chǔ)層孔隙體積的數(shù)據(jù)包括但不限于以下幾項(xiàng)：流體樣本信息、井底壓力、井測(cè)試和巖心分析。其中，井測(cè)試和井日志通常用于獲取儲(chǔ)層的地質(zhì)特征和流體性質(zhì)，而流體樣本信息可以提供有關(guān)儲(chǔ)層中流體性質(zhì)和分布的直接證據(jù)。因此，這三個(gè)選項(xiàng)都是估算含氣儲(chǔ)層孔隙體積的重要數(shù)據(jù)來源。而選項(xiàng)D、E雖然也與地質(zhì)勘探有關(guān)，但不是估算含氣儲(chǔ)層孔隙體
