Thesubaqueous distributary channel sand and distributary mouth bar are the major type of sand.

对长 6 油层组 9 口取心井进行岩心观察与描述,识别出 9 种层理和 12 种岩相,并结合测井资料研究,认为本研究区总体上为辫状河三角洲沉积体系,主要发育三角洲前缘亚相和前三角洲亚相,并划分了 6 种沉积微相,其储集砂体主要为三角洲前缘的水下分流河道砂体和河口砂体。

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 Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.

利用地震、钻井、测井等资料,将古近系沙河街组划分出7个三级层序,通过剖面沉积学分析,以优势相原则绘制不同时期各亚段沉积体系平面分布图:沙四下总体以洪水-漫湖沉积为特征,沙四上沉积时期是在滨浅湖背景之上发育了曲流河三角洲和辫状河三角洲沉积;沙三段沉积时期南部主要发育辫状河、曲流河三角洲,西北部地区发育曲流河三角洲,中部地区主要为深湖—半深湖沉积;由沙三下至沙三上,西北部三角洲规模逐渐增大,沉积范围逐渐向东、东南方向推进;沙二段沉积时期为滨浅湖沉积,在背景之上广泛发育了辫状河三角洲和三角洲沉积;沙一段以滨浅湖滩沉积为特征,南部发育了曲流河三角洲和辫状河三角洲沉积;沉积地层中的岩性圈闭以滑塌浊积岩岩性圈闭和地层侧向尖灭型岩性圈闭为主,其形成和分布主要受盆地结构、沉积古地貌和构造活动强度等因素控制,北部基山、南部江家店和瓦屋具有发育滑塌浊积扇的良好地质条件。

The site that is located on the eminence of nose structure, and far-source the underwater distributary channel and estuary bar experiencing the late dagenetic period B is the most promising for accumulation of oil and gas. Vertically, late diagenetic period B sand layer is advantageous for oil and gas gathering, while late diagenetic subperiod A3 sand layer is disadvantageous for oil and gas gathering.
