摘要：鉆井工程中鉆井管材、井下工具、井口裝置等器材和設(shè)備自始至終處于腐蝕的環(huán)境中，特別是鉆進(jìn)過程中油氣井中的CO2和H2S侵入鉆井液對鉆具進(jìn)行腐蝕，鉆井液對鉆具的腐蝕已成為影響鉆井作業(yè)成功的一個(gè)主要因素，因?yàn)楦鼡Q被腐蝕的鉆桿需要高的投資費(fèi)用，以及腐蝕會(huì)導(dǎo)致套管存在潛在的危險(xiǎn)。所以開展鉆井液性能對鉆井工具慢腐蝕特性實(shí)驗(yàn)研究，采取有效防腐措施，對保證安全、快速、高水平鉆井是必不可少的，并將使油氣田的開發(fā)獲得良好的經(jīng)濟(jì)效益。本文通過對大量文獻(xiàn)的閱讀，了解鉆井液對鉆井工具具有腐蝕性的因素，鉆具的腐蝕機(jī)理和一些防腐措施。進(jìn)行含硫鉆井液對鋼材腐蝕實(shí)驗(yàn)、含硫鉆井液的腐蝕疲勞實(shí)驗(yàn)和幾種除硫劑在不同鉆井液中除硫效果分析評(píng)價(jià)。通過改進(jìn)鉆井液性能，向含硫油氣井的鉆井液中加入合適的添加劑可以減緩其對鉆井工具的腐蝕，延長鉆具的壽命。 關(guān)鍵詞：鉆井液性能；含硫鉆井液；腐蝕；腐蝕疲勞；除硫劑
Abstract：In drilling engineering ，drilling pipe，downhole tools，wellhead equipment etc. equipment are always in a corrosive environment , especially in process of drilling，CO2 and H2S in the oil and gas wells invasive drilling fluid Corrosion on the drill tools，Corrosion of the drilling fluid on drill tools has become a major factor effect in the success of the drilling operations, because replace corroded drill requires a high investment costs, and corrosion can cause the casing to be potentially dangerous. Therefore, to carry out experimental study of the drilling fluid properties to the slow corrosion characteristics of drilling tools, take effective anti-corrosion measures, To guarantee safety，fast, high level of drilling is essential.and will get a good economic benefits in the development of oil and gas fields. This article by reading the extensive literature, understanding the corrosive factors of drilling fluid to drilling tool, the corrosion mechanism of the drilling tools and some anti-corrosion measures.Carry out sulfur-containing drilling fluid for steel corrosion test, sulfur-containing drilling fluid corrosion fatigue experiment and several desulphurization agent in different drilling fluids desulphurization effect analysis and evaluation. Through improve fluid performance, adding a suitable additive to the drilling fluid of sulfur oil and gas wells can slow down the corrosion of the drilling tools,extend the life of the drilling tools. Key word: drilling fluid properties; sulfur-containing drilling fluid; corrosion; corrosion fatigue; desulphurization agent |
