【摘要】：鉀元素是植物不可或缺的元素之一,而我國是一個農(nóng)業(yè)大國,其在農(nóng)業(yè)生產(chǎn)中的重要作用不言而喻。然而鉀鹽一直是我國的緊缺礦產(chǎn)資源之一,因此其勘探開發(fā)極為重要。柴達(dá)木盆地是我國鉀鹽主要產(chǎn)地,目前只對易開采的盆地中東部地區(qū)進(jìn)行了大規(guī)模開發(fā)。而盆地西部黑北凹地的鹽湖資源限于礦床研究程度低、開發(fā)環(huán)境相對較差,多數(shù)未能被大面積的開發(fā)。近年來西部開發(fā)條件得到改善,這必將帶動柴達(dá)木西部地區(qū)鹽湖資源的開發(fā)利用,大規(guī)模開發(fā)后也能獲得較好的經(jīng)濟(jì)效益。本文正是建立在這種背景下,從“油鉀兼探”的理論出發(fā),通過研究含鉀儲鹵層成礦的有利地質(zhì)條件及其地下構(gòu)造、地層發(fā)育特征以及盆地的演化史、地球物理特征的基礎(chǔ)上,討論了含鉀儲鹵層的成礦機(jī)理,并結(jié)合構(gòu)造地質(zhì)學(xué)、地球物理學(xué)、沉積學(xué)、盆地分析學(xué)等多學(xué)科理論進(jìn)行指導(dǎo)。通過對收集到的高精度電磁頻譜、測井資料和油氣勘探中的地震資料的研究和解譯,并利用地震屬性分析、基于模型寬帶約束波阻抗反演等地球物理特殊處理手段進(jìn)行分析預(yù)測。通過上述地球物理方法得到相對圍巖含鉀儲鹵層的地球物理響應(yīng)特征表現(xiàn)為高波速、高密度、中高伽馬、高阻抗、高磁場強(qiáng)度、中低振幅、低電阻率。以此來建立識別模式,在地震剖面中進(jìn)行儲層預(yù)測,然后通過提取平面屬性特征,結(jié)合平面構(gòu)造圖,研究含鉀儲鹵層的空間展布特征。最后結(jié)合研究區(qū)的構(gòu)造沉積特征信息圈定出含鉀儲鹵層的有利區(qū)域,在實際應(yīng)用中取得了較好的效果,為進(jìn)一步的勘探開發(fā)提供了依據(jù)。
[Abstract]:Potassium is one of the indispensable elements of plants, and China is a large agricultural country, its important role in agricultural production is self-evident. However, potassium salt has always been one of the scarce mineral resources in China, so its exploration and development is very important. Chaidamu Basin is the main producing area of potassium salt in China. At present, only the central and eastern part of the basin, which is easy to be exploited, has been developed on a large scale. However, the salt lake resources in the Heibei depression in the western part of the basin are limited to the low degree of deposit research, the development environment is relatively poor, and most of them have not been developed in a large area. In recent years, the conditions of western development have been improved, which will certainly lead to the development and utilization of salt lake resources in western Chaidamu area, and good economic benefits can also be obtained after large-scale development. Based on the theory of "both oil and potassium exploration", this paper studies the favorable geological conditions, underground structure, formation development characteristics, evolution history and geophysical characteristics of potassium-bearing halogen reservoirs. The metallogenic mechanism of potassium-bearing halogen reservoirs is discussed and guided by tectonic geology, geophysics, sedimentology, basin analysis and other multi-disciplinary theories. Through the research and interpretation of the collected high precision electromagnetic spectrum, logging data and seismic data in oil and gas exploration, and by using seismic attribute analysis, Based on the model broadband constrained wave impedance inversion and other geophysical special processing methods for analysis and prediction. According to the above geophysical methods, the geophysical response characteristics of potassium-bearing halogen reservoirs in surrounding rock are as follows: high wave velocity, high density, medium and high gamma, high impedance, high magnetic field intensity, low amplitude and low resistance. In order to establish the recognition pattern, the reservoir prediction is carried out in the seismic section, and then the spatial distribution characteristics of potassium-bearing halogen reservoirs are studied by extracting the plane attribute features and combining with the plane structural map. Finally, the favorable areas of potassium-bearing halogen reservoirs are delineated according to the structural sedimentary characteristic information of the study area, and good results have been obtained in practical application, which provides the basis for further exploration and development.
