摘要：隨著油田大斜度井及側(cè)鉆井井?dāng)?shù)逐漸增多，抽油機(jī)井管桿偏磨問題日益突出。從大港油田第一采油廠油井維護(hù)作業(yè)中管桿偏磨、腐蝕斷脫及管柱漏失井入手，介紹了目前內(nèi)襯油管及內(nèi)涂層油管處理技術(shù)的優(yōu)越性，研究確定了技術(shù)適應(yīng)性、適應(yīng)范圍，并進(jìn)行了綜合對(duì)比分析評(píng)價(jià)。室內(nèi)實(shí)驗(yàn)證實(shí)，內(nèi)襯油管磨損量低于N80油管，對(duì)接箍磨損量基本為零，起到了雙向保護(hù)作用；具有耐磨涂層轉(zhuǎn)移膜的油管磨損實(shí)驗(yàn)后表面仍比較平滑。兩種技術(shù)均顯示了較好的耐磨性能。現(xiàn)場應(yīng)用數(shù)據(jù)表明，兩項(xiàng)技術(shù)減緩了管桿偏磨腐蝕，延長其自身檢泵周期一倍以上，拓寬了防偏磨技術(shù)思路，具有較高的經(jīng)濟(jì)效益，為今后井筒油管柱磨蝕治理技術(shù)水平的提高奠定了基礎(chǔ)。

Abstract:With the number of highly deviated wells and side drilling wells gradually increased, the problem of eccentric wear of rod for pumping wells was highlighted. We originated from the corrosion and broken on suck rod and tubing leakage during oil well maintaining work in No.1 Oil Production Plant in Dagang Oilfield. The superiority of lining tubing and undercoated tubing was introduced. According to research, we found the adaptability and scope about this kind of technology, and then made a comprehensive comparison to get an analysis and evaluation. Indoor experiments confirmed lined tubing wear was less than N80 tubing, and the amount of wear butt hoop was almost zero, which played the role of bi-directional protection. Tubing wear of resistant surface coating transfer film was still relatively smooth after the experiment. Both of the techniques showed good wear resistance. Field application data showed that the two technology slowed pipe rod eccentric wear corrosion, extended the own pump inspection period over one time, and broadened the technical ideas on avoiding suck with high economic benefit, which laid a foundation on technology improving of governing the corrosion and broken on suck rod and tubing.

Key words: abrasion; tubing; lining; internal coating; pump inspection period

隨著油田開發(fā)進(jìn)入中、高含水期，油藏地質(zhì)狀態(tài)、油井井身情況發(fā)生較大變化，大斜度井及側(cè)鉆井井?dāng)?shù)逐漸增多，抽油機(jī)井管桿偏磨造成的斷、磨、漏問題日益突出。每年因油管、抽油桿偏磨腐蝕造成的作業(yè)量占油井全部維護(hù)工作量的20%～30%，增加了作業(yè)費(fèi)用和管桿投入費(fèi)用。近幾年來，通過綜合治理，偏磨問題得到一定緩解，但仍是造成油井免修期短的主要原因。……
