【摘要】：針對現(xiàn)有除垢技術(shù),新疆油田提出了一種集輸管線快速集結(jié)聚垢除垢的方法,并發(fā)明了一種專用裝置用來定點集結(jié)除垢。該裝置改變了常規(guī)防除垢的思路,人為地設(shè)計模擬流體的結(jié)垢環(huán)境,實現(xiàn)流體在特定裝置中的定點集結(jié)聚垢,快速除垢。然而,各因素對結(jié)垢速率的影響尚不明確,嚴(yán)重影響了該裝置集結(jié)聚垢除垢的能力。鑒于此,本文通過搭建循環(huán)管路實驗平臺研究影響結(jié)垢因素與結(jié)垢速率之間的規(guī)律,提出集結(jié)聚垢裝置優(yōu)化運行參數(shù)與結(jié)構(gòu)參數(shù),對該裝置在新疆油田的進(jìn)一步推廣和應(yīng)用具有極大的意義。首先,論文基于結(jié)垢理論,流體力學(xué)、熱力學(xué)和材料力學(xué),自主設(shè)計并搭建一套自動化水力環(huán)路實驗平臺,并通過單因素和均勻?qū)嶒炑芯繙囟取毫土髁繉Y(jié)垢速率的影響規(guī)律。研究表明:25≤溫度≤65℃時,結(jié)垢速率隨著溫度的升高不斷增大;0.20≤壓力≤1.65MPa時,結(jié)垢速率隨著壓力的升高不斷增大;0.8≤流量≤7.8 m3/h時,結(jié)垢速率隨著流量的增大先增大后減小,且增大與減小的拐點隨著溫度的升高不斷增大。在此基礎(chǔ)上,分析篩網(wǎng)對結(jié)垢速率的影響規(guī)律,結(jié)果顯示,單層40目304不銹鋼篩網(wǎng)結(jié)垢能力強(qiáng)于單層8目普通鋼材篩網(wǎng),三層304不銹鋼篩網(wǎng)結(jié)垢能力強(qiáng)于單層304不銹鋼篩網(wǎng)。為了定量分析以上各因素對結(jié)垢量的影響規(guī)律,通過SPSS軟件對均勻?qū)嶒灲Y(jié)果進(jìn)行非線性回歸,得到結(jié)垢量預(yù)測模型,并通實驗驗證模型的精度。最后,通過Matlab軟件編程對該模型進(jìn)行求解,得到集結(jié)聚垢裝置最優(yōu)運行參數(shù),即溫度T=65℃、壓力P=1.65MPa和流速V=0.6738m/s。
[Abstract]:In view of the existing scale removal technology, a method of rapid accumulation of scale and scale removal for gathering pipeline is proposed in Xinjiang Oilfield, and a special device is invented to collect and remove scale at a fixed point.This device changes the conventional anti-scaling idea, artificially designs the scale environment of simulated fluid, and realizes the fixed point accumulation of the fluid in the specific device, and the rapid scale removal.However, the influence of various factors on the scaling rate is not clear, which seriously affects the ability of the equipment to accumulate scale and remove scale.In view of this, this paper studies the law of influencing scaling factors and scaling rate by setting up a circulating pipe experimental platform, and puts forward the optimized operation parameters and structural parameters of the scale accumulation device.It is of great significance for the further popularization and application of this device in Xinjiang Oilfield.Firstly, based on scaling theory, hydrodynamics, thermodynamics and material mechanics, a set of automatic hydraulic loop experimental platform is designed and built, and the temperature is studied by single factor and uniform experiment.Influence of pressure and flow rate on scaling rate.The results show that when the temperature is below 65 鈩，
