One is that,by the shove of passive rift valley polycycle,quartz sandstone with high maturity of lithologic composition deposits on the background of sub-plain during sag period;together with the rock formation environment of paranormal saltless local water,the reservoir characterized b.

厘定该盆地这种突出商业价值的地质因素主要表现在以下两个方面：1被动裂谷的多旋回推移，在坳陷期的准平原背景下沉积了高岩石成分成熟度的石英砂岩，加之超淡地层水的成岩环境，最终形成盆地的高孔高渗储层；2&教科书&式的生储盖组合。

Sequence stratigraphy Ⅱ contains not only mudstonds of deep-lake subfacies with large thickness and wide distribution, but also rich sandstones of fluvial facies, fan delta facies, delta facies, and is the main sequence with source-reservoir-caprock assemblage combination.

Lower Cretaceous belong to retrograding sedimentary sequence of tide-flat-carbonate platform facies,and have good hydrocarbon source rock and reservoir rock but no good cap rock.

下白垩统属退积的潮坪—碳酸盐岩台地沉积序列，生、储油层发育，但盖层发育相对较差，有可能在靠近改则—尼玛断裂带附近形成一些与逆冲断层有关的小型油气藏。

This paper analyzes the gas reservoir formation condition of all the rift s in the north part of Songliao Basin, and proposes the apparent difference of hydrocarbon source rock development, organic matter evolution and cap rock condition among the rift s.

在深入分析松辽盆地北部各断陷天然气成藏条件的基础上，指出各断陷在烃源岩发育、有机质演化程度和盖层条件上存在明显的差异。

Petroleum systems in half-grabens extend along the slope, while petroleum systems in grabens are basically restricted between two boundary faults or extend slightly.

盆地早第三纪经历了3个裂陷期，均发育有烃源岩、储层和局部盖层，形成的含油气系统存在着依次改造相互叠加组合的关系。

Basic geological conditions for migration and accumulation mode of the deep marine basin are similar to the shallow ones, but the basin has deeper sags and rifts, bigger deposits and infillings, developed source rocks, and good source-reservoir-caprock associations.

该深水盆地油气运聚成藏的基本地质条件亦与浅水区类似，但陆坡深水区凹陷裂陷更深、沉积充填规模更大，且发育4套烃源岩和3套储盖组合类型，使深水油气运聚成藏有了良好的基础。

Volcanic rocks shaped by a volcanic movement tend to occur vugs and fissures as spaces for hydrocarbon storage during rapid magma condensation;the volcanic debris deposits are characterized by expanding and dispersing in water,being either favorable to packing pores,and becoming good sealing caps,or to preservation of oil/ga...

火山活动形成的火山岩，在岩浆迅速冷凝过程中会产生孔洞和缝隙，成为容留油气的空间；火山活动形成的火山灰沉积，具有遇水膨胀和分散的特点，地层孔隙被其它充填后而成为良好的封存盖层并能抗御新构造运动的破坏而有利于油气田的保存；火山活动提供1020～1200℃的岩浆和300～400℃的热液流体携带的热能，为油气运移提供热动力条件，促进油气运移；火山活动在沉积盆地内形成的火山岩体与侵入岩体，为含油气盆地增加了一种非构造圈闭———火山岩岩性圈闭。

Late pool-forming periods and the Tertiary undercompacted mudstone forming large area of pressure sealings are advantageous to the preservation of natural gas.

成藏期晚和第三系欠压实泥岩形成大面积的压力封盖，有利于天然气的保存。

In order to look for new prospecting replacing territory ,this paper researched systematically the hydrocarbon source rock condition, reservoir rock condition, cover condition, trap type, natural gas migratory-concentration procession and conservation condition, etc., to analyze overall the natural gas enriching and forming reservoir conditions of the Paleozoic in southeastern Ordos Basin, discussed its natural gas prospecting foreground, pointed out the beneficial prospecting targets and put forward concrete prospecting strategy.

目前，鄂尔多斯盆地中北部已发现多个天然气田，为寻找新的勘探接替区域，从储集条件、烃源岩条件、封盖条件、圈闭类型、天然气运聚成藏过程和保存条件等方面入手，对鄂尔多斯盆地东南部古生界天然气的富集与成藏条件进行了全面分析，探讨了其天然气勘探前景，指出了有利勘探目标，并提出了具体的勘探部署意见。

Hard work pays off, as expected in the weathering profile of the mottled soil off the surface of a white quartzite seen to build a small thumb-shaped scraper, a pleasant surprise in their minds, this is a major accident harvest.

功夫不负有心人，果然在剖面风化剥落的杂色土面上见到了一件白色石英岩小姆指盖状刮削器，他们心中一阵惊喜，此为一个意外的重大收获。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
