Low permeability sandstone reservoirs generally are defined as oil reservoirs with gaspermeability of less than 50md,in China. They can be further graded into three types basedon values of permeability and development scheme. Accroding to their geological occurrence,low permeability sandstone reservoirs in Chinacan be classified into three categories:primary low permeability reservoirs,secondary lowpermeability reservoirs and fractured low permeability reservoirs. Reservoir description andevaluation would be different in different types of low permeability sandstone reservoirs.The characteristics of low permeability sanstone reservoirs in China are small diameterof pore throats,high capillary pressure,low oil saturation,high clay content,and easily sub-jecting formation damage to reduce producibility. The maturity of sediments of reservoirs islow,and their diagenetic maturity is high.Many low permeability sandstone reseroirs are lowresistance oil reservoirs,lithologic trap reservoirs,and have natural fractures. As discribedabove,they will result in some of difficulty for reservoir study and development.

低渗透砂岩储层系指空气渗透率小于50md的含油砂岩储层,按其渗透率大小及开采方式可细分为三类;另根据地质成因,我国低渗透砂岩储层分为三种类型,即原生低渗透储层、次生低渗透储层和裂缝性低渗透储层。不同成因类型的低渗透砂岩储层,其储层描述与评价方法各异。我国低渗透砂岩储层的地质特点:沉积物成熟度低,成岩成熟度高;孔喉半径小,毛管压力高;原始含油饱和度低;粘土矿物含量高,在钻井、完井和开采过程中极易造成伤害。大多数低透储层测井反映为低电阻率,以岩性圈闭及岩性一构造圈闭油藏为主,天然裂缝比较发育。因此,认识和开采此类油藏难度较大。

Daihai lake is located in central inner Mongolia and is a modern faulted basin of terrestrial factes. This modern basin is well comparative with the faulted basin of Meozoic and Cenozoic era in the eastern part of China. Deltas is often important infilling sandbodies in faulted basin of terrestrial factes. Therefore, this peper is mainly emphasized on the analysis and Study on the depeitional processes and the favorable reservior sandbodies on different sedimentary scales of two delays in the direction of short axis in Daihai lake basin. One delta, called Yuanzigou delay, is located in thenorthern steep slope of the lake basin, while another one, Bulianghe detla, in the sourthen gentle slope of the lake basin. Both are fluvial-dominated braided deltuic system with coarse deceits.Provenances of two delays are varying form eath other. Yuanzigou river is a short distance ephemeral braided stream and Bulianghe river a long distance ephemeral braided stream.Through element analysis of lithology, grain size, sedimentary structures, thickness of sandbeds, clastic components and color etc., the description and interpretation of the depositional features of two delays are provided. 12 lithofacies or genetic factes form two delays have been defined. Their mutual assemblages in verprofile make up different type of lithofaices assemblages or vertical sedimentary sequences, each corresponding to a cerium depeitional process and subenvironment. Therefore, nine sedimentury sequences have been recognized which reflect depositztional features in different perts of two btaided delays. The four sedimentary sub environments or sedimentary factes zones of each delay were distinguished by depeitional features,that is, (1) upper delta plain, (2) lower delta plain, (3) delta front slope and (4) pre-delta.The two delay have been modelled. There are both similarities and differences of depositional features among Yuanzigen delta and Bulianghe delay. Moreever depositional precesses and features between fan delta and braided delta have been discussed in this paper.There exists apparent control of depeitional processes and sedimentary factes zones on the reservoir of two delays.The deltas of the steep and gentle slope in the direction of short axis in the faulted barn have some different features of sedimentary and geometry shape of sandbodies.Finally,through sedimentary sequences, porosity zones and sandbodies geometry of two delays, the sketch model of two delays,sandbody at 3-D sauce extension in each sedimentary zones have been set up.

粗粒三角洲是陆相湖盆的主要充填实体,然而,在中国东部陆相湖泊断陷盆地或裂谷型盆地中,由于盆地短轴方面断层陡缓程度的差异所造成的不对称性断陷盆地,使得其沉积充填实体之一的三角洲也因此而出现其各自的特色和差异。为此,本文通过岱海湖短轴方向陡、缓两侧辫状河三角洲沉积特征的比较来阐明各自的储层地质特点及与扇三角洲的区别,进而分析不同背景下辫状河三角洲的沉积特点、储层沉积学规律和砂体骨架在三维空间展布的地质模型。
