Pore is not only an important texture in carbonatite but also an importantstorage space for oil and gas as well as for the layered or stratabound solid metallic deposits. The Devonian carbonate pore of Hunan Province is classtfied intothree types based on genetic classification, they are original pore, secondary poreand secondary fissure. High surfacial porosity is concentrated on the top of QiZhiqiao formation and on the transitional layer of the bottm of She Tiangiaoformation. The average surfacial porosity is between 1.8-2.57%, Therefore,this layer is available for oil and gas reserve and for ore storage space.More complex micro pore type in carbonatite specially in low porosity micritecarbonate can be found by the observation under the scaning electron microscope.Dolomitization and recrystallization as well as pressure solution are suitable forthe formation of secondary pore. The later superimposition by solution and leach-ing may form and enlarge the araible pore so as to improve the surfacial porosi-ty. The secondary porosity and surfacial porosity are high in the fresh waterunder flow compress-cemented rocks of the too of Qi Ziqiao formation and thetransitional layer of the bottom of She Tianqiao formation.

将湖南泥盆系碳酸盐岩的孔隙(显孔隙)按成因划分为原生孔隙、次生孔隙和次生裂隙3类。面孔隙率较高的岩石集中于棋梓桥组上部及佘田桥组下部的过渡层位,平均面孔隙率为1.80~2.57%,因而该层位是较为有利的油气储集及容矿空间。用扫描电镜观察碳酸盐岩特别是孔隙率偏低的泥晶碳酸盐岩可以发现更为复杂的微孔隙类型。白云石化作用、重结晶作用及压溶作用有利于次生孔隙形成。而稍晚的溶解及淋溶作用叠加可形成并扩大有效孔隙,提高岩石的面孔隙率。发育于棋梓桥组上部及佘田桥组下部过渡层位的淡水潜流压实一胶结等5种成岩相中岩石的次生孔隙率和面孔隙率较高。

Located in the centre of Hunan Province and with an area about 6 000 km 2,Lianyuan Basin has a series of NE NNE trend brachy synclines,there are Lower Carboniferous Ceshui and Upper Permian Longtan coal measures in the Basin,and the coal beds are mainly distributed in the brachy synclines. The two sets of coal measures are humic coal with kerogen and strong gas generating.The small primary vesicles of coal rock are more than 90%,the secondary vesicles,endogenetic and secondary cracks also exist in coal,which make the coalbed methane be mainly adsorbed gas,and the free gas secondarily.The gas contains methane primarily,weight and non hydrocarbons gas slightly.The permeability of coal is low,but it can be improved by stimulating gas bearing reservoir.According to the results of resources assessment of the coalbed methane,three high,middle gas bearing zones can be located,and the prospective areas of gas exploitation are in southwest upwarping hinge and its vicinities of the brachy synclines near E W trend Longshan mole track at the southern edge of Lianyuan Basin.

位于湖南中部的涟源盆地,发育一系列北东—北北东向的短轴向斜,面积近6000km2。盆地内有下石炭统侧水组和上二叠统龙潭组两套煤系,煤层主要分布于向斜中。两套煤系的煤层均为腐殖煤,有机质属Ⅲ型干酪根,具较强的生气能力。煤岩中原生小气孔占90%以上,也有次生气孔和内生、次生裂隙,这就决定了煤层气的赋存以吸附状态为主,游离状态为辅。煤层气的组分主要为甲烷,含微量重烃气及非烃气。煤层的渗透率总体较低,但通过解放储层开采的措施,可显著提高渗透性以利于煤层气的抽放。根据煤层气资源评价结果,可在盆地内划分出3个高、中富气区,而两煤系煤层气的开发远景区均在靠近盆地南缘龙山东西向隆起带的各含煤向斜西南仰起端及其附近。
