伊格尔砂岩的下部单元是分选良好的岩屑质和海相海绿石质。

The paper analyzed the basic characteristics of sandstone T2 spectra by NMR experiments and theoretical research, determined the quartz sandstone and lithic sandstone T2 cutoff value.

论文通过核磁共振试验和理论研究，分析了本区砂岩谱的基本特征，确定了石英砂岩和岩屑砂岩的截止值。

Lithic sandstone tant has high porosity and permeability that is relative low fractal dimension, the greater the rock fractal dimension, and of the poorer, more complex pore structure.

岩屑砂岩之间孔隙度、渗透率相对较高的具有较低的分数维。

Feldspar and lithic feldspar fine sandtone are mainly sandstone.

储层以细粒长石砂岩、岩屑长石砂岩等为主。

The results indicate the reservoir is characterized by low-permeability, low compositional and structural maturity, abundant plastic lithic fragment and matrix.

结果表明，该区沙二上4-7砂层组为小型闭塞陆相断陷湖盆三角洲前缘沉积，其岩石成分和结构成熟度低，塑性岩屑和杂基含量高，属于低渗透储层，目前处于晚成岩A1亚期。

Studies show that it is a set of turbidity sedimentary under the condition of deep-water environment in rift deep depressing period with the characteristics of multiphase and mutability, The lithology of reservoir is chiefly mid-fine grained conglomerate and lithic mixed sandstone, as well as the gravel-bearing sandstone next. Sand bodies in the plane are controlled by water channel obviously, resulting in NW-oriented banded distribution.

研究表明，大凌河油层是裂谷深陷期深水环境条件下形成的一套浊流沉积物，沉积物具有多期性和突变性，主要岩性以中－细砾岩和岩屑质混合砂岩为主，次为含砾砂岩，砂体在平面上受水道控制明显，呈北西向的条带状展布。

The results show that the sandstone reservoirs with high porosity and permeability are mainly composed of coarse-grained lithic quartz sandstone and quartz sandstone with relatively well-preserved primary intergranular pores, relatively large median radius and average pore throat radius, and relatively low displacement pressure.

结果表明：组成高孔、渗储层的砂岩类型主要是粗粒的岩屑石英砂岩和石英砂岩，其较多地保存了原生粒间孔，具有较高的中值半径和平均喉道半径以及较低的排驱压力；高能环境下有利的沉积微相和成岩早期包壳状胶结物对原生粒间孔隙的保护作用是形成高孔、渗储层的基础条件。

Acid-fracturing treatment and testing technology level have great impact for testing production. The reservoir can be damaged easily and the uncertainty for calibrating log interpretation will increase according to testing conclusions.⑶ Lithology complex (quartz sandstone, lithic sandstone, arcose), the reservoir has different characteristics with different lithology. Conventional log interpretation methods can not accurately identify the various sandstone.

酸化压裂和试油工艺水平对测试产能的影响很大，储层容易被伤害，使根据试油气结论进行测井解释标定的不确定性增大；⑶岩性（石英砂岩、岩屑砂岩、长石砂岩）复杂，不同岩性的储层具有不同的特征，常规测井解释方法无法准确的识别各类砂岩岩性等。
