【摘要】：鉆孔數(shù)據(jù)是地質(zhì)中最常見且最簡(jiǎn)單的數(shù)據(jù),利用鉆孔數(shù)據(jù)直接建立三維地質(zhì)模型已經(jīng)成為國(guó)內(nèi)外學(xué)者研究的焦點(diǎn)。在研究前人多種地質(zhì)建模方法的基礎(chǔ)上,結(jié)合工程實(shí)踐,提出一套具有工程實(shí)用價(jià)值的優(yōu)化地質(zhì)建模方法。該方法以鉆孔數(shù)據(jù)為基礎(chǔ)數(shù)據(jù),將鉆孔地質(zhì)剖面數(shù)據(jù)融入到地質(zhì)建模中,修正了以往建模中尖滅點(diǎn)位置取值1/2區(qū)域的不合理情況,生成精確位置地層尖滅線;并且在建模的過程中加入了依據(jù)剖面圖數(shù)據(jù)的模型調(diào)整。最后通過建模實(shí)例驗(yàn)證了該方法的準(zhǔn)確性與有效性。
[Abstract]:Borehole data is the most common and simplest data in geology. It has become the focus of scholars at home and abroad to establish 3D geological model directly from borehole data. Based on the research of many geological modeling methods and engineering practice, a set of optimal geological modeling methods with practical engineering value is put forward. This method takes drilling data as the basic data and integrates the borehole geological profile data into the geological modeling. It corrects the unreasonable situation of 1 / 2 region where the point out point position is taken in the previous modeling, and generates the accurate position stratum tip extinguishing line. And the model adjustment based on the profile data is added in the modeling process. Finally, the accuracy and validity of the method are verified by a modeling example.
