作者何奕言（2019）在《通化盆地下白垩统亨通山组沉积特征及储层发育规律研究》一文中研究指出：通化盆地属于吉林省东部盆地群,其盆地主要形成时期是下白垩统,而盆地性质属于断陷盆地。通化盆地的西北部分与柳河盆地接壤,而东南部邻近集安盆地。本文在基于前人研究成果的基础上,通过一系列新的地质钻井,对所采取的岩芯样品进行镜下鉴定、压汞分析测试等一系列的室内分析工作。研究了通化盆地亨通山组的沉积特征,并对通化盆地亨通山组储层的岩石学特征、孔隙结构特征等进行研究,对亨通山组的储层发育规律进行探讨,取得了以下认识。1.通化盆地亨通山组发育的岩石类型和沉积相类型通化盆地亨通山组共识别出4类岩石类型:分别为碎屑岩类、火山碎屑岩类、火山碎屑沉积岩类和火成岩类;进一步可以划分为10亚类、24个基本类型。识别出4类沉积相类型:扇三角洲前缘、冲积扇、湖相和火山岩相;又细划分为7个亚相,23个微相类型。2.通化盆地亨通山组沉积相平面展布特征通化盆地亨通山组在三棵榆树坳陷主要发育火山岩相-湖泊沉积,在三源浦坳陷中发育的则是扇三角洲前缘和冲积扇沉积。S1层序:在三源浦坳陷发育扇三角洲前缘沉积;三棵榆树坳陷为火山岩相-湖泊沉积。S2层序:在三源浦坳陷发育冲积扇沉积;而三棵榆树坳陷为火山岩相-湖泊沉积。S3层序:三源浦坳陷发育冲积扇沉积;三棵榆树坳陷发育火山岩相-湖泊沉积。3.通化盆地亨通山组的储层特征通化盆地亨通山储层主要岩石类型由砾岩、砂岩、粉砂岩、凝灰质砂岩、凝灰岩和凝灰熔岩等组成。亨通山组储层的孔隙类型主要分为4个大类,细分为6个亚类;其中次生熔孔和构造裂缝较为发育。通过分析测试,发现亨通山组储层为特低孔-低孔、超低渗透储层。对通化盆地亨通山组的14个样品进行了压汞测试分析;然后依据大庆油田对储层的划分标准对其储层进行评价,其中5个样品为Ⅲ类储层,属于差储层;其余9个样品属于Ⅳ类储层,属于很差储层。4.通化盆地亨通山组储层的成岩作用类型及阶段亨通山组储层的成岩作用类型主要有压实-压溶作用、胶结与熔结作用、交代作用、重结晶作用、溶蚀溶解作用,以及火山物质的冷却固结作用。总体上,亨通山组储层的成岩作用阶段处于中成岩A期,属于低成熟-成熟阶段。5.通化盆地亨通山组储层的发育规律研究认识亨通山组储层主要受到沉积作用和成岩作用的影响。经过研究发现亨通山组储层的有利沉积相为水下扇相和火山岩相,前者因为水动力条件强,砂体厚度相对较大,颗粒较粗;后者则是因为熔岩快速冷却成岩而具有一定的抗压实能力,原生气孔裂缝发育。但是由于亨通山组储层的成岩作用较为复杂,首先较大的埋深导致压实作用强烈,研究区的砂岩转变为致密砂岩,其物性条件很差。而后在遭受了火山作用和其他的成岩改造后,虽然出现了部分次生溶蚀孔隙,但是其原生孔隙被破坏,同时大量的自生黏土矿物生成,将孔隙填充并堵塞喉道,导致储层物性差。
