【摘要】：壓縮天然氣儲氣井作為我國使用非常廣泛的天然氣存儲設(shè)備,需定期檢測以確保其安全使用。在儲氣井使用過程中,由于井筒內(nèi)外壁存在腐蝕現(xiàn)象,井筒減薄甚至破損是儲氣井失效的主要原因之一,可造成巨大的經(jīng)濟損失及安全事故。本文針對目前儲氣井壁厚檢測設(shè)備中存在的設(shè)備體積較大,成本較高以及在井中移動不暢等現(xiàn)象,研究了一種基于水浸法的儲氣井超聲波壁厚檢測系統(tǒng)。本系統(tǒng)包含一款儲氣井超聲波測厚儀及一個超聲波數(shù)據(jù)分析軟件,儲氣井超聲波測厚儀通過內(nèi)置超聲探頭及嵌入式系統(tǒng)完成對壁厚信息的采集,并傳輸至超聲波數(shù)據(jù)分析軟件進行分析。本文的主要研究內(nèi)容如下:(1)針對儲氣井測厚的實際情況及國家相關(guān)檢測要求,在綜合分析國內(nèi)外測厚設(shè)備優(yōu)缺點的基礎(chǔ)上,提出了基于水浸法的儲氣井超聲波壁厚檢測系統(tǒng)架構(gòu),為儲氣井超聲波壁厚檢測系統(tǒng)的設(shè)計提供了框架指引。(2)應(yīng)用水浸法超聲波測厚原理,提出了儲氣井超聲波壁厚檢測系統(tǒng)每部分的設(shè)計要求,對儲氣井超聲波壁厚檢測系統(tǒng)的超聲波測厚儀嵌入式系統(tǒng)、超聲波測厚儀機械結(jié)構(gòu)、升降系統(tǒng),及超聲波數(shù)據(jù)分析軟件的開發(fā)進行了詳細的設(shè)計開發(fā),完成了一套輕便易攜、高效穩(wěn)定的儲氣井超聲波壁厚檢測系統(tǒng)。(3)對儲氣井超聲波壁厚檢測系統(tǒng)進行實驗室及現(xiàn)場測試,以驗證其是否能夠達到精度要求和發(fā)現(xiàn)實際應(yīng)用中的現(xiàn)場問題。對發(fā)現(xiàn)問題進行整理和分析,并進行相應(yīng)的改進,使得目前的儲氣井超聲波壁厚檢測系統(tǒng)具備了實際應(yīng)用水平。
[Abstract]:As a widely used natural gas storage equipment in China, compressed natural gas storage wells need to be inspected regularly to ensure their safe use. During the operation of gas storage wells, due to the corrosion of the inner and outer wall of the wellbore, hole thinning or even damage is one of the main reasons for the failure of the gas storage wells, which can cause huge economic losses and safety accidents. In view of the phenomena of large volume, high cost and difficulty moving in the gas storage well wall thickness measuring equipment, a kind of ultrasonic wall thickness detection system based on water immersion method is studied in this paper. The system includes a gas storage well ultrasonic thickness meter and an ultrasonic data analysis software. The gas storage well ultrasonic thickness meter completes the collection of wall thickness information through the built-in ultrasonic probe and embedded system. And transmitted to the ultrasonic data analysis software for analysis. The main research contents of this paper are as follows: (1) in view of the actual situation of gas storage well thickness logging and the national relevant testing requirements, based on the comprehensive analysis of the advantages and disadvantages of domestic and foreign thickness measuring equipment, The structure of ultrasonic wall thickness detection system for gas storage wells based on water immersion method is put forward, which provides a frame guide for the design of ultrasonic wall thickness detection system in gas storage wells. The design requirements of every part of ultrasonic wall thickness measurement system of gas storage well are put forward. The embedded system of ultrasonic thickness measuring instrument, the mechanical structure of ultrasonic thickness measuring instrument and the lifting system of ultrasonic wall thickness measuring system of gas storage well are introduced. And the development of ultrasonic data analysis software has carried on the detailed design and development, has completed a set of portable, easy to carry, high efficient and stable ultrasonic wall thickness detection system of gas storage wells. The ultrasonic wall thickness detection system of gas storage wells has been tested in laboratory and on the spot. In order to verify whether it can meet the accuracy requirements and find practical problems in the field. The problem is sorted out and analyzed, and the corresponding improvement is made, which makes the current ultrasonic wall thickness detection system of gas storage well have practical application level.
