【摘要】：滇東地區(qū)是典型的多煤層地區(qū),具有高應(yīng)力、構(gòu)造復(fù)雜、構(gòu)造煤發(fā)育等特點(diǎn),使得目前比較常見(jiàn)的選區(qū)方法和指標(biāo)很難在該區(qū)直接應(yīng)用。本論文以滇東多煤層發(fā)育區(qū)為研究對(duì)象,以眾多含煤向斜和礦區(qū)為基本研究單元,在大量煤田地質(zhì)勘探資料和煤層氣井資料基礎(chǔ)上,結(jié)合實(shí)驗(yàn)室測(cè)試分析數(shù)據(jù),分析了研究區(qū)構(gòu)造條件、沉積特征、水文條件等宏觀控氣地質(zhì)因素,探討了含煤性、含氣性、滲透性、資源可采性等煤層氣地質(zhì)條件特征;分別運(yùn)用“關(guān)鍵要素遞階優(yōu)選法”和“煤儲(chǔ)層能量系統(tǒng)法”進(jìn)行了煤層氣有利目標(biāo)區(qū)和靶區(qū)優(yōu)選,提出了一套適合研究區(qū)的多煤層煤層氣地質(zhì)選區(qū)指標(biāo)體系和方法。以煤層氣地質(zhì)資源量、煤層氣地質(zhì)資源豐度、煤層氣可采資源量、煤層氣可采資源豐度、埋深1000m以淺地質(zhì)資源量、滲透率、臨儲(chǔ)比為關(guān)鍵評(píng)價(jià)要素,運(yùn)用“關(guān)鍵要素遞階優(yōu)選法”對(duì)滇東地區(qū)眾多含煤向斜(礦區(qū))進(jìn)行了煤層氣有利目標(biāo)區(qū)優(yōu)選。結(jié)果顯示,老廠為最有利區(qū);恩洪、阿崗、圭山為較有利區(qū),其中恩洪更佳;新莊、昭通為一般有利區(qū);羅木、倘塘、寶山、來(lái)賓、鎮(zhèn)雄、羊場(chǎng)等為不利區(qū)。針對(duì)老廠、恩洪有利目標(biāo)區(qū),基于“煤儲(chǔ)層能量系統(tǒng)”選區(qū)方法,利用煤層氣成藏三元判識(shí)標(biāo)志參數(shù),定量表征了煤儲(chǔ)層的有效運(yùn)移系統(tǒng)和有效壓力系統(tǒng),在恩洪、老廠有利目標(biāo)區(qū)內(nèi)進(jìn)行了煤層氣勘探開發(fā)“靶區(qū)”優(yōu)選。結(jié)果顯示,恩洪礦區(qū)Ⅱ構(gòu)造單元和老廠礦區(qū)四勘區(qū)為最有利靶區(qū)。
[Abstract]:East Yunnan is a typical multi-coal seam area with the characteristics of high stress, complex structure and development of tectonic coal, which makes it difficult to apply the common selection method and index directly in this area. This paper takes the development area of multi-seam in eastern Yunnan as the research object, taking many coal syncline and mining area as the basic research units, based on a large number of coalfield geological exploration data and coalbed gas well data, combined with the laboratory test and analysis data. The structural conditions, sedimentary characteristics and hydrological conditions of the study area are analyzed, and the characteristics of coal-bearing, gas-bearing, permeable and recoverable coal-bed methane geological conditions are discussed. In this paper, the "key element hierarchical optimization method" and "coal reservoir energy system method" are used to optimize the favorable target area and target area of coalbed methane, and a set of multi-coalbed methane geological selection index system and method suitable for the study area are put forward. Taking the geological resources of coalbed methane (CBM), the abundance of CBM (coalbed methane), the recoverable resources (CBM), the depth (1000m) of CBM as the key evaluation elements, the quantity of shallow geological resources, the permeability and the ratio of adjacent reserves are the key evaluation elements. By using the method of hierarchical selection of key elements, a number of coal-bearing synclines (mining areas) in eastern Yunnan are selected for the favorable target area of coal-bed methane (CBM). The results show that the old factory is the most favorable area; Enhong, Agang and Guishan are the more favorable areas, of which Enhong is better; Xinzhuang, Zhaotong is the general favorable area; and Lamu, Luantang, Baoshan, Guest, Zhenxiong and Sheep Farm are unfavorable areas. In view of Laochang and Enhong favorable target area, based on the method of "coal reservoir energy system", the effective migration system and effective pressure system of coal reservoir are quantitatively characterized by using the three dimensional identification criteria parameters of coalbed methane reservoir formation, and the effective migration system and effective pressure system of coal reservoir are quantitatively represented in Enhong. In the favorable target area of the old factory, the target area of coalbed methane exploration and development has been selected. The results show that the second tectonic unit and the fourth prospecting area of Laochang mining area are the most favorable target areas.
