摘要

摘要: 川西北广元—陕西宁强间下志留统巨厚的暗色泥岩地层中赋存有数以百计的生物礁，包括堤礁、点礁、堤状点礁群、生物岩丘、灰泥丘、层状岩丘，出露好，大小不一。礁是在浅水陆棚泥岩相的基础上发育起来的.造礁生物主要为横板珊瑚属的链珊瑚和蜂窝珊瑚及泡孔目的皮壳状、半球状苔藓虫。礁发育的基底主要为泥基质疙瘩状灰岩，也可以是生屑滩、近基风暴岩和淹没的潮坪层纹石灰岩。礁的衰亡以淹死型为主，少数为旱死型。在广元河湾场地区的河深１井钻遇礁组合５３.５５ｍ，中途测试有气浸显示、川南井下亦钻遇生物灰岩、生清灰岩（可能即为生物礁），见沥青充填裂隙、晶洞。包绕礁体的暗色泥岩有机炭丰度高。因之，志留系生物礁有希望成为四川盆地潜在的油气勘探目的层。

Abstract: Between Guangyuan. Sichuan to Ningqiang. Shaanxi province, Within giant-thick dead color mudstones of lower Silurian there are hundreds of reefs developed，including barrier reef, patch reef, barrier-like patch reefs, biohorm，Limemud mound and bed-rock mound. All of them are out Groped well and a great disparity in size. The reefs developed on the bases of the mudrock facies of the shallower shelf. The reef-building organism are mainly Halysites. Favorites, subalveotella,paleaofavosites, and clathrodictyon, Rosenella. The basesment rock on which reefs grooved is mainly mudbasis-knollenakalk and some are on the bioclast bank，the proximal tempestites and sumerged tidal flat stratifera limestones. Many of the reefs declimed and fell because of drove and a few of them died for drought. The reef is over 50 meters thick in the Hoshen 1 well and Ho 15 well in Guangyuan. North-west Sichuan，and a litter gas was gotten in it. Also, the reef was found in many wells in the southern Sichuan. In addition，the reefs is distributed over the eastern Sichuan，Northern Guizhou and western Hebui, the character of reef Complex is similar to that of the studied area. Bitumen filling crack and vug is often found. The organic carbon content in dead color mudstone which wraped up the reefs is high. There for. It is hope for the reef of the lower Silurian to be the exploration bojective formation in the Sichuan basin.
