Ebstract System in East Depression of the Liaohe basin is at the diagenesis stage. The correlation between the Extractable Organic hater (EOM), kerogen the the Bio-thermocatalytic Transition Zone Oases (BTZG) in the source rocal has ben discussed in this paper. It is discovered that there exist different organic source materials in the EOM and kerogen of the same sample. A higher carbon -number preference of the saturated hydrocarbons, and a sghicant distribution of land plantderived biomarkers, i. e., C29 sterane, pimarane, abieboe, r-lupane and oleanane in the EOM show that the EOM is characterized by orpoic matter of type, Ⅱ-Ⅲ. However, the carbon i8OtOPic competion of the keroggn indicate that it mainly consists of organic matter of type Ⅰ -Ⅱa. The difference in organic compositions between the EOM and kerogen at the diagenesis stage can be explained by the selective accumulation of sedhoenlary orpoic matter. Specific IR absorption spectra and corresponding parameters of bitumen A, non-hydrocarbons and asphaltene show the same pattern of variation in the depth Of 1850 ̄ 3060m. Three evolution stages have been determined in this study. The EOM are rapidly degradated in about 2200-2770m, i. e., the stage. and highest at about 2500m, which results in fotming BTZO. Although kerogens are characteristic of deoxygen and delipidic groupo at the sarge, they have no direct relationS to the formation Of BTZG beCause they mainly Produce depolyineric betumen at the stage. Therefore the EOM, especially non-hycrocarbons and asphaltene, could be considered as the most important source materials of BTZG in East Depression of the Liaohe basin.

辽河盆地东部凹陷中部沙一段和沙二段烃源岩主要处于成岩演化阶段,本文通过对其可溶有机质和干酪根的研究探讨了它们与过渡带气之间的关系,发现可溶有机质与同一样品的干酪根之间往往表现出不同的生源组成,前者以Ⅱσ—Ⅲ型有机质为特征,而后者主要属Ⅰ—Ⅱ.型母质。在埋深1850~3060m的范围内,沥青A、非烃和沥青质的红外特征吸收及其有关参数呈一致的变化规律。由此划分出三个明显不同的演化阶段.并指出2200~2770m左右为沥青A、非烃和沥青质急剧降解的阶段,2500m左右达到高峰,其结果与过渡带气的形成密切相关。干酪根在该阶段虽然也表现出脱氧、脱脂基因特征,但以生成解聚沥青为主,与过渡带气不存在直接的联系。因此认为可溶有机质,尤其是其中的非烃和沥青质是东部凹陷过渡带气最主要的母源物质。

It is known that the relationship between volcanic rock and sandstone presents negative correlation in thickness. Well D25 is just in where with thin volcanic rock, while the thick volcanic rock exists in both sides of there. So that the location of D25 is a swale in Paleogeomorphology.The study indicated...

Under the influence of rift movement of Tertiary, many times of magma eruption have occured and thus the volcanic rocks were widely distributed in Dapingfang area in southern East Depression of Liaohe rift. It is known that the relationship between volcanic rock and sandstone presents negative correlation in thickness. Well D25 is just in where with thin volcanic rock, while the thick volcanic rock exists in both sides of there. So that the location of D25 is a swale in Paleogeomorphology.The study indicated that the regional direction of paleocurrent is in the NE-SW, but the date of diplog shows that is in the NW-SE. The analysis infers that the direction of paleocurrent was abruptly turned in the D25 area. Under the action of erosion caused by secondry flow, a package of coarse sediment was superimpositionally deposited in the flut of channel near concave bank, and the conglomeratic sandstone is excellent reservoir and has better oil and gas bearing potential. The study of the deposit offers a new type of reservoir and provides a new thinking for hydrocarbon exploration.

河流深槽沉积体是河流沉积的一种特殊沉积体。辽河坳陷第三纪断裂活动强烈,火山岩广泛分布,形成了独特的地貌条件,具备形成河流深槽沉积体的地质条件。本文以辽河坳陷东部凹陷大25井区为例,对河流深槽沉积体的成因及特征进行探讨,证实了大25井区巨厚砂砾岩沉积是河流在火山岩古地形的限制下发生急转弯,在其变曲河段的深槽中沉积的深槽沉积体。该沉积体中发育良好的储集空间,有利于油气储集。该类储集体的发现,丰富了辽河坳陷的储层类型,为油气勘探提供了新的领域。

Xihu sag is located in the central part of east depression of east China sea continental shelf basin. The 20 years exploration proves it a sag enriched with condensate gas. The sag can be divided into 5 secondary tectonic belts, the main sedimentary formation is Tertiary and the main source rock is Pinghu coal measures of Eocene. Condensate gas pools are enriched at the west slop and the central folded anticlinal belt of the sag, till now, 2 oil gas fields and 3 hydrocarbon-bearing structures tested...

Xihu sag is located in the central part of east depression of east China sea continental shelf basin. The 20 years exploration proves it a sag enriched with condensate gas. The sag can be divided into 5 secondary tectonic belts, the main sedimentary formation is Tertiary and the main source rock is Pinghu coal measures of Eocene. Condensate gas pools are enriched at the west slop and the central folded anticlinal belt of the sag, till now, 2 oil gas fields and 3 hydrocarbon-bearing structures tested from sandstone of Pinghu formation have been discovered at west slop; 4 gas-bearing structures have also been discovered at the southern sector of central folded anticlinal belt, but the main gas producing pay are the sandstones in the middle part of Huagang formation, Oligocene.The oil and gas enrichment is mainly controlled by 3 factors: (1)Regional tectonic development and good cooperation in the time and space of the generation, discharging and accumulation of hydrocarbon;(2)favourable reservoir-seal assemblage;(3)the closing and opening of fault in tectonic stress field.

西湖凹陷位于东海陆架盆地东部拗陷中部,经近20年的勘探,已证实是个富含凝析气的凹陷。该凹陷分为5个二级构造带,沉积地层以第三系为主,主要烃源岩为始新统平湖组煤系。凝析气藏富集在凹陷的西部斜坡带和中央褶皱背科带南段,前者已发现2个油气田和3个含油气构造,凝析气产自平湖组砂岩;后者已发现4个含气构造,主要产气层为渐新统花港组中部砂岩。区内的油气富集主要受3个因素控制:①区域构造发展及局部构造形成期与生、排烃期在时空上的配合;②具有利的储盖组合;③在构造应力场中造成断层的封闭性和开启性。勘探证明,西湖凹陷必将成为我国海上的重要产气基地。
