3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 近日,在中石化重慶涪陵頁巖氣開發(fā)區(qū),勝利石油工程井下作業(yè)公司運(yùn)用帶壓作業(yè)技術(shù),成功完成焦頁10-1HF井作業(yè)施工任務(wù)。這是中石化首次在頁巖氣領(lǐng)域運(yùn)用帶壓作業(yè)技術(shù)。
當(dāng)井筒內(nèi)存在壓力時(shí),運(yùn)用帶壓作業(yè)技術(shù),可以在不壓井、不放壓的情況下起管柱,最大限度地實(shí)現(xiàn)對油氣層和環(huán)境的保護(hù),有利于油氣水井修復(fù)后的穩(wěn)產(chǎn)和提高注水效率。
帶壓作業(yè)技術(shù)在國外已經(jīng)廣泛應(yīng)用,形成了較為完善的配套技術(shù)體系。在國內(nèi),帶壓作業(yè)技術(shù)應(yīng)用已經(jīng)逐漸成為行業(yè)所趨,尤其是在重慶涪陵頁巖氣田,不壓井作業(yè)最大限度地保護(hù)了原有地層,更有利于油氣井修復(fù)后的穩(wěn)產(chǎn)高產(chǎn)。
自去年以來,勝利石油工程井下作業(yè)公司為進(jìn)一步增強(qiáng)技術(shù)儲(chǔ)備,自主成立了中石化首個(gè)帶壓作業(yè)培訓(xùn)中心,購置相關(guān)研發(fā)教材及設(shè)備資源。在施工期間,公司還專門聘請美國CUDD公司技術(shù)人員到現(xiàn)場進(jìn)行技術(shù)指導(dǎo),全面掌握了帶壓作業(yè)技術(shù)要領(lǐng)。
