以下一句句的分析。
The well-developed ASP flooding technology has yield significant productivity of oil but some problems especially caused by the injected alkali emerge at the same time.
分析：感覺(jué)這一句比較精簡(jiǎn)。用has yield significant productivity of oil 也更專業(yè)些，比一般的對(duì)著直譯翻譯要好。再用but轉(zhuǎn)折，接著用especially caused by the injected alkali 點(diǎn)出“特別是注入的堿造成的不利因素”這一句并且將冒號(hào)前后的句子拆分成兩句，此處翻譯的甚為精要。注：“不利因素”可不翻譯，采用省略譯法，因?yàn)?font face="Times New Roman"> problems especially caused 后面的肯定是不利因素，已經(jīng)暗含了這個(gè)信息，所以“不利因素”沒(méi)有必要翻譯。
The alkali can lead to the dispersion and migration of formation clay resulting in the decrease of formation permeability, can form alkali scale with reservoir fluids and rock minerals giving rise to the damage to formation and malfunction of oil wells, and can bring about great reduction in the viscoelasticity of polymer thereby decreasing the swept volume.
分析：上句說(shuō)了是堿造成的不利因素，這句緊接著就說(shuō)具體是哪些東西造成的，和上句緊緊相連。
這句翻譯堿造成的哪些不利因素，也就是冒號(hào)后面的那些。此句采用連動(dòng)手法構(gòu)成一句，由三個(gè)小分句組成的（動(dòng)詞我給加粗了）。每一個(gè)分句又有意思，分別使用 resulting in、 giving rise to 、 thereby +動(dòng)名詞做后置定語(yǔ)表示結(jié)果，都是表示結(jié)果，卻各有千秋，不用相同的詞表示，讀起來(lái)也朗朗上口啊。感覺(jué)組織的煞費(fèi)苦心啊。看似是一句話，其實(shí)表達(dá)了一大段的東西，內(nèi)部結(jié)構(gòu)不錯(cuò)。
However the surfactant-polymer flooding without alkali can reduce the damage to formation and scaling in wellbores, can maximize the viscosity and elasticity of polymer, and can produce lower interface tension.
分析：使用However 引出第三句，基于三元驅(qū)的不利因素，那么可以順理成章地說(shuō)出聚/表二元復(fù)合體系的好處，就是這句了。這句也是采用三個(gè)動(dòng)詞連動(dòng)的手法，顯得精簡(jiǎn)扼要。
As a result, at the same cost of chemicals, surfactant-polymer flooding can obtain the same effect with the ASP flooding and may become a new technology alternative to the ASP flooding.
分析：接下來(lái)，再用As a result引出下一句，注意 the same with的用法，使用may become a new technology alternative to the ASP flooding翻譯可能成為一種代替三元復(fù)合驅(qū)的新技術(shù)，這是多么簡(jiǎn)練又地道啊。
