The contacting measurement method with a double probe is put forward after the detailed analysis of the state - of - the - art measuring methods of the thickness of wall. firstly, the theory - profile generatrix is built, and then the movement curve of the track of joint center is constructed, which aims at making the joint center move along the movement curve and keep the fixed sensor touching the wall. the measuring sensor examines the line in its normal direction of the interior wall all the time, the data from the sensor is the thickness value of the wall
論文通過分析國內外變曲率回轉體壁厚測量的現狀，提出了雙測頭接觸式測量方案:通過構造理論輪廓母線，建立鉸鏈中心的運動曲線，使鉸鏈中心始終沿運動曲線運動，以保證固定觸頭與傳感器測頭的連線始終在內壁法線方向上，從而傳感器測頭所得的數值即為壁厚值，該方案經模擬測試實驗取得了預期效果。 -
The data acquisition and data flow for various sensor carriers are analyzed systematically, and the calculation models are put forward. the model of quantification of wall - loss defects for in - line inspection with ultrasonic pigs has been established. and inspection data can be pretreated with this model, compressed with dpcm technique and treatd by dsp instruments
建立了檢測頭數據採集量及數據處理速率模型，首次建立了管道壁缺陷液浸超聲檢測的量化分析模型；提出採用該模型進行數據預處理后，採用差分脈碼調制技術進行數據壓縮，採用dsp器件提高數據處理速率。 -
Abstract : anchor packer is one of the important downhole tools which areused in oil production and waterflood technical operation, such as layer waterflood, layer fracture or acidation, mechanical water block. after anchor is fixed in the simulated test unit, the invasion depth of the casing can be known with the help of the sensor around the casing wall, and then the failure degree is concluded. this is very important for the anchor packer design and site operation
文摘:在油田開發中封隔器是實施機械採油、分層注水、分層壓裂或酸化、機械卡堵水等注采工藝作業的主要井下工具之一，封隔器上的卡瓦是保證工作可靠性的重要元件，把卡瓦安裝在模擬試驗裝置中，通過在套管壁周圍分佈位移傳感器，測得卡瓦錨定后切入套管壁深度，判斷卡瓦對套管的損傷程度，這對封隔器的設計和現場使用具有十分重要的意義。 -
Starting with automation system, this paper, firstly, outlines the status of sensor lying in automation field and its developing state, shows the superiority about eddy current test by comparing it with the other nondestructive tests, expatiates the modern developing state about eddy current technology both here and there, shows the vista about eddy current test in our country and the background of the subject about the test for the width and thickness of stripe in the in - wall of cylinder after laser thermal treatment. secondly, beginning with maxwell equation in electromagnetic field theory and combining with some electromagnetic phenomena in real life, this paper explains qualitatively the operating principle about eddy current technology and the test theory for multi - parameter test with multi - frequency by math illation and gives some applying occasions about it
