塔里木盆地的构造演化及找气前景

在古生代克拉通盆地找气工作中,除了注意在克拉通内浅水滨海沼泽相和陆棚相盆地继续寻找和勘探天然气外,应当特别重视在克拉通内或边缘深水拗陷型盆地找气。塔里木盆地满加尔拗陷早古生代盆地即属于这种类型。烃源岩裂解后生气潜力要比浅水拗陷大得多。根据目前获得的资料分析,该拗陷具备有生成大量石油和天然气的物质基础。在邻近拗陷的塔北隆起上已发现的雅克拉凝析气藏表明,这是一个很有希望找到大型油藏和气藏的地区。成藏的有利条件主要是:     

开展油气储地球物理研究，促进油气开发工作

一、概述 在油田开采中,当油井进入老年期产油量逐渐减少时,常常需要为后期生产确定具体的技术方案。同时,为了更有效地挖掘油气藏的潜力,采用更合理的开采方法,科学地扩展油气藏的范围,八十年代以来,国际上出现了一个新的应用地球物理学分支,即油气储地球物理学(或称开发地球物理学)。 油气储地球物理学是以多分量跨孔地震,多偏移距垂直地震剖面(VSP)和高分辨率四维反射地震,各种井间的层析成象,综合地球物理测井为主要手段,结合石油地     

Formation Conditions and Distribution Regularities of Oil—gas Pools in Tertiary Volcanic Rocks in Western Huimin Depression,Shandong Province

The formation conditions and distribution regularities of oil-gas pools in volcanic rocks in western Huimin Depression have been studied in terms of geolgic,sesmic and well logging information,This paper discusses the types and lithofacies,development and distribution of Tertiary volcanic rocks in the area.The results demonstrate that volcanic activity occurred mainly during the period from the Sha-4 stage to the Guantao episode,i.e.,before the oil-generating period(before the end of the Guantao episode and the Minghuazhen episode).The activity did not destroy oil and gas formation and accumulation,but was favourable for the concentration of organic matter and its conversion to hydrocarbons;besides,volcanic rocks can serve as reservoir rocks and cap rocks,playing a role very similar to that of a syndepositional anticline,The volcanic rocks are distributed near the margins of the oil-generating depression;there are many secondary interstices in the rocks,which are connected with each other.These are the leading conditions for the formation of oil-generating period and their self-sealing or good combination with other cap rocks are important factors for forming volcanic rock-hosted oil and gas pools.The oil-gas pools associated with volcanic rocks in western Huimin are mainly distributed around the deep oil-generating depression,in the central up lift or the high structural levels on the margins of the depression.In particular,the sites where several faults cross are usually locatons where hith-yielding oil-gas pools in volcanic rocks are concentrated.
