在大宛齐油区识别出了三角洲平原和三角洲前缘两个亚相并从中进一步划分出了8种微相，查明了康村组岩性由不同粒级的岩屑砂岩的组成，分流河道砂体、水下分流河道砂体和河口砂坝砂体是油气的主要储集层，储层在纵向上多期叠置、在横向上频繁迁移、尖灭和连续性较差。

Second, the study determines that there are five sedimentary facies types including fan delta, braided delta, nearshore subaqueous fan, sublacustrine fan and beach bar, according to the identification of facies marks as well as comprehensive analyses of the content of conglomerate and sandstone, sandstone thickness, mudstone color, detrital composition and other data of Shahejie Formation in the western beach area of Liaohe Basin. There are three main provenance areas consisted of western uplifting, Huludao uplifting and central low uplifting.

通过相标志的识别以及对砾岩含量、砂岩含量、砂岩厚度、泥岩颜色及碎屑组分等资料的综合分析，确定了滩海西部地区沙河街组主要发育扇三角洲、辫状河三角洲、近岸水下扇、湖底扇和滩坝五种储层沉积相类型，并存在西部凸起、葫芦岛凸起和中央低凸起三个主要的物源区。

The researches show that fan delta, alluvial plain, delta, lacus and sublacustrine fan develop, each sedimentary facies are divided into several subfacis again. The probability cumulative grain size curves incude "uphill arched arc" pattern, one segment pattern, bi-segment pattern, tri-segments pattern, multi-segments pattern, complicated bi-segment pattern, complicated tri-segments pattern,"low slope multi-segments" pattern,"high slope multi-bouncing population-one suspension population" pattern,"high slope multi-bouncing population-one suspension population-transitional zone" pattern,"high slope and multi-bouncing population" pattern,"broadly uphill arched arc" pattern and so on, each subfacis has own peculiar probability cumulative grain size curves.

研究表明，该地区发育的沉积相有扇三角洲、冲积平原、三角洲、湖泊、湖底扇，每一种沉积相又分为几种沉积亚相类型；该地区碎屑岩的粒度概率累积曲线特征主要包括：&上拱弧形&式、一段式、两段式、三段式、多段式、复杂两段式和复杂三段式、&低斜多段&式、&高斜多跳一悬&式和&高斜多跳一悬夹过渡&式、&高斜多跳&式、&宽缓上拱&式等，每种沉积亚相类型对应其独特的粒度概率累积曲线特征。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征，研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪；N1层属于低孔、特低渗储层，孔隙类型以原生、次生粒间溶孔为主；分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用；进行了储层评价与有利相带预测，将储层分为三类并划分了有利区带、较有利区带，认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带，储层以Ⅰ、Ⅱ类为主。

Weak negative Ce/Ce* anomaly indicate the marine origin,as well as terrigenous contribution.

弱的Ce/Ce*负异常，说明了海相沉积成因，也表明陆源碎屑物对沉积岩的主导作用。

In contrast , the content of terrigenous sediment shows an opposite glacial-interglacial variation pattern.

分别用元素TiO2、CaO估算出沉积物中陆源碎屑的含量及CaCO3的含量，结果显示CaCO3在间冰期时高，而在冰期时低，表现出&大西洋旋回&的特征。

In the northern South China Sea, variations of carbonate content are mainly controlled by dilution of terrigenous sediment.

南海北部碳酸钙百分含量主要受控於陆源物质对碳酸盐的稀释作用，即海平面低位时陆源碎屑经过陆架进入较深海域增多，也称稀释旋回。

In terms of the strata-overlaping from south to north, the trend of facies types from distal facies in the south to proximal facies in the north, and terrigenous sediments transported from north to south, there disappeared old land in the north.

从地层由南向北超覆，相类型由北部的近源相至南部的远源相，以及碎屑搬运方向总体从北向南的变化趋势，更加确定了以前认为北部存在一个消失的古陆的认识。

The results indicate that the CaCO3 cycle at this SCS locality was strongly influenced by terrigenous dilution.

陆源碎屑含量与CaCO3含量相反，显示出南海CaCO3旋回属于稀释旋回。

Sedimentary analyses show that ore-bearing Baifeng Formation belongs to a set of terrigenous clast turbidite, including Bouma sequence and turbidite fan channel system.

沉积学分析表明，含矿的百逢组为一套陆源碎屑浊积岩，包括鲍马序列和浊积水道体系。
