【摘要】：黃縣盆地為一中生代形成、新生代繼承發(fā)展的近海煤與油頁巖共生盆地。盆地內(nèi)地層沉積受黃縣—九里店大斷層控制。本文通過對研究區(qū)內(nèi)北皂礦井、梁家礦井以及北馬資源接替區(qū)進(jìn)行井下和鉆孔巖石樣品系統(tǒng)的采樣和分析測試,以及對區(qū)域各層油頁巖詳細(xì)的化驗(yàn)數(shù)據(jù)的搜集,并通過宏觀微觀相結(jié)合的分析方法,分析研究了研究區(qū)內(nèi)部油頁巖含油率特征、賦存特征、地球化學(xué)特征等。通過大量的鉆井巖心、露頭、測井曲線的觀察與分析,劃分出盆地內(nèi)油頁巖地層沉積相類型；以單井沉積相為基礎(chǔ),分析黃縣盆地研究區(qū)內(nèi)部朱壁店組和李家崖組沉積相垂向特征。對黃縣盆地西部含煤與油頁巖層系進(jìn)行了層序地層劃分及對比,通過單井層序地層分析和連井層序地層劃分確定盆地煤與油頁巖形成于水進(jìn)體系域的湖泊沼澤環(huán)境。對北皂1403工作面主采層油2段上下7.9m內(nèi)的油頁巖、炭質(zhì)泥巖、含油泥巖進(jìn)行連續(xù)采樣,以此為例,根據(jù)微量元素測試分析結(jié)果,進(jìn)一步論證了盆地煤與油頁巖形成于溫暖而潮濕氣候下的淡水到半咸水的淺水環(huán)境。在此基礎(chǔ)上,通過構(gòu)造作用、沉積環(huán)境分析和有機(jī)質(zhì)來源等研究,確定了研究區(qū)煤與油頁巖生成和分布控制因素,總結(jié)了黃縣盆地研究區(qū)煤與油頁巖的共生規(guī)律,最后作出油頁巖成礦模式圖。
[Abstract]:Huangxian Basin is a Mesozoic and Cenozoic inherited offshore coal and oil shale symbiotic basin. The deposit of the inland layer of the basin is controlled by Huangxian-Jiulidian big fault. In this paper, the samples and analysis of rock samples from underground and drilled rock in Beizhai Mine, Liangjia Mine and Beima Resource replacement area in the study area, as well as the collection of detailed laboratory data of oil shale in various layers of the region, are carried out. The characteristics of oil shale oil content, occurrence and geochemistry in the study area are analyzed by combining macro and micro analysis methods. Through the observation and analysis of a large number of drilling cores, outcrops and log curves, the sedimentary facies of oil shale formation in the basin are divided into two types, which are based on single well sedimentary facies. The vertical characteristics of sedimentary facies of Zhubiedian formation and Lijiaya formation in Huangxian Basin are analyzed. The sequence stratigraphic classification and correlation of coal-bearing and oil shale strata in the west of Huangxian Basin are carried out. The lacustrine swamp environment formed by coal and oil shale in the basin is determined by single-well sequence stratigraphic analysis and multi-well sequence stratigraphic division. The oil shale, carbonaceous mudstone and oil-bearing mudstone are continuously sampled from the oil shale, carbonaceous mudstone and oil-bearing mudstone in the upper and lower parts of the main oil layer of Beizao 1403 working face. The results of trace element test and analysis are taken as an example. The shallow water environment from fresh water to brackish water formed by coal and oil shale in warm and humid climate in the basin is further demonstrated. On this basis, through the study of tectonic action, sedimentary environment analysis and source of organic matter, the factors controlling the formation and distribution of coal and oil shale in the study area are determined, and the symbiotic law of coal and oil shale in the study area of Huangxian Basin is summarized. Finally, the metallogenic model map of oil shale is made.
