【摘要】：隨著經(jīng)濟(jì)的快速發(fā)展,石油的現(xiàn)有開采量越來越難以滿足市場的需要,而且老油田的不斷開采導(dǎo)致開采的難度不斷加大,提高石油的產(chǎn)量成為石油行業(yè)的重要研究課題,因此本課題以石油增產(chǎn)為背景,借助于虛擬現(xiàn)實(shí)技術(shù),針對(duì)石油增產(chǎn)工藝流程進(jìn)行了三維模擬仿真,為石油增產(chǎn)過程建立可視化直觀的模擬仿真結(jié)果,對(duì)石油增產(chǎn)過程的實(shí)施具有非常重要的指導(dǎo)意義并為其提供理論依據(jù)。本論文選取石油開采生產(chǎn)工藝流程為研究對(duì)象,確定了該生產(chǎn)過程的最終工藝流程圖,對(duì)該流程中使用到的化工設(shè)備的幾何形狀和功能進(jìn)行了分析和簡化,創(chuàng)建了對(duì)應(yīng)設(shè)備的三維虛擬模型,著重于化工單元設(shè)備的幾何建模、可裝配性單元設(shè)備的設(shè)計(jì)、普適的連接方式設(shè)計(jì)、交互方式等進(jìn)行了討論和探究,制定了虛擬裝配的規(guī)則和約束條件,在設(shè)定的約束條件下,構(gòu)建了非常逼真的石油增產(chǎn)虛擬漫游仿真環(huán)境,并使用具有健壯性的場景結(jié)構(gòu)圖對(duì)該三維虛擬環(huán)境進(jìn)行管理,該場景根節(jié)點(diǎn)下有三個(gè)子節(jié)點(diǎn)場景節(jié)點(diǎn)、裝配臺(tái)節(jié)點(diǎn)和克隆臺(tái)節(jié)點(diǎn)場景節(jié)點(diǎn)專門為渲染三維虛擬場景服務(wù)的,后兩個(gè)節(jié)點(diǎn)以及它們的子節(jié)點(diǎn)是裝配過程中的主要操作對(duì)象,基于已知的約束條件和新的算法對(duì)這些節(jié)點(diǎn)進(jìn)行轉(zhuǎn)化和變換,實(shí)現(xiàn)化工生產(chǎn)線的準(zhǔn)確、真實(shí)、智能的虛擬裝配。另外在石油增產(chǎn)物理模型的基礎(chǔ)上建立了增產(chǎn)彈爆燃的動(dòng)力學(xué)模型和溫度場擴(kuò)散模型,并利用計(jì)算機(jī)進(jìn)行了數(shù)值求解,結(jié)合三維虛擬仿真技術(shù)對(duì)仿真結(jié)果可視化的演繹出來,繪制出了爆燃泄壓段的溫度場的三維動(dòng)態(tài)分布圖,為石油增產(chǎn)作了重要鋪墊。
[Abstract]:With the rapid development of economy, it is more and more difficult to meet the needs of the market because of the existing oil production, and the continuous exploitation of the old oil field leads to the increasing difficulty of exploitation. Increasing the output of oil has become an important research topic in the petroleum industry. Therefore, with the background of increasing production of oil and virtual reality technology, the three-dimensional simulation for the process of increasing oil production has been carried out. Visual and visual simulation results are established for the process of increasing oil production. This paper selects the petroleum production process as the research object and determines the final process flow chart of the production process. The geometric shape and function of the chemical equipment used in the process are analyzed and simplified, and the 3D virtual model of the corresponding equipment is established, with emphasis on the geometric modeling of the chemical unit equipment. The design of assemblable unit equipment, universal connection mode design, interaction mode and so on are discussed and explored, and the rules and constraints of virtual assembly are established under the set constraint conditions. A very realistic virtual roaming simulation environment for oil production is constructed, and the robust scene structure diagram is used to manage the 3D virtual environment. There are three child node scene nodes under the root node of the scene. Assembly node and clone node scene node is dedicated to rendering three-dimensional virtual scene nodes, the latter two nodes and their children are the main operation objects in the assembly process. Based on the known constraints and new algorithms, these nodes are transformed and transformed to realize the accuracy and reality of the chemical production line. In addition, based on the physical model of increasing oil production, the dynamic model and the diffusion model of temperature field were established, and the numerical solution was carried out by computer. Based on the visualization of the simulation results, the three-dimensional dynamic distribution of the temperature field in the deflagration pressure relief section is drawn, which makes an important foreshadowing for the increase of oil production.
