1、論文題目：子長礦區(qū)煤油地質(zhì)特征及合理開發(fā)對策研究工程領(lǐng)域：地質(zhì)工程工程碩士：張健(簽名)指導(dǎo)教師：侯恩科王雙明(簽名)摘要子長礦區(qū)位于陜西省延安市北部，該礦區(qū)煤、油資源共生，資源儲量豐富，石油和煤炭這兩種產(chǎn)于三疊系上統(tǒng)延長群的資源在垂向上相互重疊，煤炭開采和石油開發(fā)已經(jīng)相互產(chǎn)生了不同程度的制約和不利影響。開展子長礦區(qū)煤油地質(zhì)特征及開發(fā)對策研究對促進(jìn)礦區(qū)持續(xù)發(fā)展具有重要意義。本文在總結(jié)子長礦區(qū)地層、構(gòu)造、水文地質(zhì)、工程地質(zhì)和開采技術(shù)條件的

2、基礎(chǔ)上，研究了子長礦區(qū)的煤油地質(zhì)特征，圈定了煤炭可采區(qū)與石油分布區(qū)范圍。子長礦區(qū)含煤地層為三疊系上統(tǒng)瓦窯堡組，可采煤層為3號和5號煤層。含油地層為三疊系上統(tǒng)延長群，共分為五段和十個油層組。煤層與油層主要呈煤上油下疊置關(guān)系。通過對現(xiàn)有煤油資源開發(fā)現(xiàn)狀調(diào)查，煤油資源開發(fā)中的相互影響問題較為突出，主要表現(xiàn)在煤炭開采導(dǎo)致部分油井破壞甚至報廢，油井的存在制約了煤炭大規(guī)模生產(chǎn)，壓占了大量的煤炭資源并威脅煤礦安全生產(chǎn)工作。針對子長礦區(qū)煤油資源共存，部

3、分地區(qū)同時開發(fā)的實際，提出了保煤采油和保油采煤的思路和對策。根據(jù)子長礦區(qū)煤、油地質(zhì)特征及勘查研究程度、開采現(xiàn)狀結(jié)合煤炭、石油發(fā)展規(guī)劃，將該區(qū)劃分為煤油共采區(qū)（Ⅰ）、石油優(yōu)先開采區(qū)（Ⅱ）、煤炭優(yōu)先開采區(qū)（Ⅲ）三類合理開發(fā)分區(qū)，并提出了三類開發(fā)分區(qū)相應(yīng)的開發(fā)對策。關(guān)鍵詞：子長礦區(qū)；煤炭地質(zhì)；石油地質(zhì)；特征；開發(fā)對策研究類型：應(yīng)用研究Subject:TheResearchontheCoalPetroleumGeologicalFeatures
