【摘要】：在不同結(jié)構(gòu)的采油井環(huán)境下繪制三維井眼軌跡和井眼軌跡中井筒管柱的靜態(tài)組合是虛擬現(xiàn)實(shí)領(lǐng)域中的一個(gè)重要問題。怎樣利用本課題將井下作業(yè)管柱的組成、井眼軌跡的顯示在一個(gè)虛擬的場(chǎng)景中以一個(gè)三維可視化的平臺(tái)展現(xiàn)在工作人員面前,加深工程作業(yè)人員對(duì)運(yùn)動(dòng)力學(xué)模型以及防偏磨方案的理解。進(jìn)行此方面的課題研究,具有廣泛的應(yīng)用前景和很高的實(shí)際應(yīng)用價(jià)值。本文分析和研究了井眼軌跡的繪制算法,并在此基礎(chǔ)上進(jìn)一步研究了井筒的三維顯示技術(shù)。在分析對(duì)比各種測(cè)斜算法后,選取符合實(shí)際需求的測(cè)斜計(jì)算模型,同時(shí)將預(yù)測(cè)井眼軌跡進(jìn)行繪制,按照已經(jīng)繪制成型的井號(hào)類型進(jìn)行適應(yīng)油田生產(chǎn)需求的井下作業(yè)管柱的模擬生成,整個(gè)過程以三維可視化的方式呈現(xiàn)。本文提出了一種對(duì)于井眼軌跡的新繪制方法,利用VSL語言實(shí)現(xiàn)點(diǎn)、線、面的繪制,將井眼軌跡曲線筒狀化,并為其設(shè)計(jì)人機(jī)交互功能,增強(qiáng)系統(tǒng)的趣味性。通過對(duì)三維模型的讀取、中心軸的設(shè)定、模型定位與碰撞檢測(cè)技術(shù),完成井下作業(yè)管柱的生成與對(duì)井筒的交互操作。本課題旨在建立采油虛擬現(xiàn)實(shí)實(shí)驗(yàn)平臺(tái),該平臺(tái)采用三維可視化技術(shù),將鉆井、井下等多種業(yè)務(wù)基礎(chǔ)數(shù)據(jù)和業(yè)務(wù)知識(shí)綜合起來建立井筒三維可視化模型,進(jìn)行井下作業(yè)管柱三維靜態(tài)仿真,用于井下作業(yè)指導(dǎo)與管理,有助于井下作業(yè)人員相互交流與協(xié)作,還可以進(jìn)行井眼軌跡的顯示,井下管柱各生命周期的模擬。通過三維井眼軌跡的實(shí)時(shí)動(dòng)態(tài)繪制與井下工藝管柱的自由組裝,實(shí)現(xiàn)整個(gè)井下開采過程的三維展示,讓用戶沉浸在這個(gè)虛擬的環(huán)境里,并了解和掌握井下作業(yè)的具體生成流程,制訂一系列科學(xué)生產(chǎn)的原則和規(guī)范,為工程人員提供強(qiáng)大的輔助決策支持方面具有重大意義。
[Abstract]:It is an important problem in the field of virtual reality to draw the static combination of the borehole string in the 3D well trajectory and the wellbore trajectory in the environment of different structures. How to make use of this subject to make up the downhole working string is an important problem in the field of virtual reality. The well trajectory is displayed in a virtual scene with a three-dimensional visual platform, which deepens the understanding of the motion mechanics model and the anti-bias wear scheme of the engineering workers. This paper analyzes and studies the algorithm of hole trajectory drawing, and further studies the 3D display technology of wellbore. The slanting calculation model is selected to meet the actual demand. At the same time, the predicted well trajectory is drawn, and the downhole working string is simulated according to the type of well number that has been drawn to meet the production demand of oil field. The whole process is presented as 3D visualization. In this paper, a new drawing method for borehole trajectory is proposed. The drawing of points, lines and surfaces is realized by VSL language, and the borehole trajectory curve is cylindrical, and the human-computer interactive function is designed for it. Enhance the interest of the system. By reading the 3D model, setting the center axis, locating the model and collision detection technology, The purpose of this project is to establish a virtual reality experimental platform for oil production. The basic data and knowledge of underground operation can be integrated to establish a three-dimensional visualization model of borehole and carry out three-dimensional static simulation of downhole operation string, which can be used to guide and manage downhole operation, which is helpful for the communication and cooperation of downhole operators. It can also display borehole trajectory, simulate the life cycle of downhole string, and realize the 3D display of the whole downhole mining process through the real-time dynamic drawing of 3D borehole trajectory and the free assembly of downhole technological string. It is of great significance for users to immerse themselves in this virtual environment, to understand and master the concrete generating process of downhole operations, to formulate a series of principles and norms for scientific production, and to provide strong auxiliary decision support for engineers.
