【摘要】：三維地質(zhì)建模及可視化技術(shù)是當(dāng)前石油勘探等領(lǐng)域的熱點(diǎn)技術(shù),它不僅可以解決石油勘探等領(lǐng)域所面臨的技術(shù)難題,而且也具有很高的理論研究價(jià)值。由于在地質(zhì)建模過程中針對(duì)原始數(shù)據(jù)的預(yù)處理,往往需要專業(yè)人員根據(jù)鉆孔信息,結(jié)合專家經(jīng)驗(yàn),并根據(jù)傳統(tǒng)的工程勘察二維圖,進(jìn)行地層劃分和空間解釋,所以很難根據(jù)鉆孔信息自動(dòng)進(jìn)行地層劃分。同時(shí),在對(duì)虛擬鉆孔數(shù)據(jù)進(jìn)行插值時(shí),也不能保證地層分配的準(zhǔn)確性。針對(duì)上述問題,本文綜合運(yùn)用已有的理論與實(shí)際成果,摒棄傳統(tǒng)的二維圖分層方法,利用DEM內(nèi)插算法,構(gòu)建多層的規(guī)則DEM,并通過擬合地質(zhì)函數(shù)解決地層層面相交問題。通過技術(shù)對(duì)比分析,本文選擇較為流行的不規(guī)則網(wǎng)格TIN三角劃分來簡化地層界面,并在傳統(tǒng)TIN數(shù)據(jù)結(jié)構(gòu)中加入層編號(hào),以GTP模型為基礎(chǔ),結(jié)合TIN三角劃分,根據(jù)層編號(hào)由上至下逐層鏈接拓?fù)?建立了一個(gè)基于錄井實(shí)際數(shù)據(jù)的三維模型,解決了傳統(tǒng)GTP模型因其具有廣義三棱柱體的特性而在顯示過程中容易出現(xiàn)空洞等實(shí)際問題。實(shí)踐表明,本文所提出的依據(jù)混合模型進(jìn)行建模并可視化的技術(shù)滿足錄井企業(yè)的真實(shí)需求,是一個(gè)高效、可行的解決方案。
[Abstract]:The 3D geological modeling and visualization technology is a hotspot of current oil exploration and other fields, it can not only solve the technical problems of petroleum exploration in the field, but also has a high research value. The pretreatment for the raw data in geological modeling process, often need professional personnel according to the drilling information, combined with the expert experience, and according to the 2D pattern of traditional engineering survey, stratigraphic division and spatial interpretation, so it is difficult to drill hole information automatically according to the stratigraphic division. At the same time, the interpolation of virtual borehole data, can not guarantee the accuracy of formation distribution. According to the above problems, this paper uses existing theories and practical results, abandon the two-dimensional the traditional method of hierarchical graph, using DEM interpolation algorithm, constructing multi-layer rules of DEM, and through the fitting function to solve the geological problems. Through the layers to faces This paper analyzed and compared, choose the more popular irregular grid TIN triangulation to simplify the formation interface, and add layer number in the traditional TIN data structure, based on GTP model, combined with the TIN triangulation, according to the number of layers from top to bottom layer link topology, established a three-dimensional model based on actual logging data, solve the traditional GTP model due to its characteristics of generalized triangular prism and the display process is prone to empty problems. Practice shows that based on the hybrid model presented in this paper are the real needs of modeling and visualization technology to meet the logging enterprises, is an efficient and feasible solution.
