| 摘 要： | 储集层岩石微观孔隙结构特征直接反映了储集层的渗流能力,为储集层评价提供重要依据。通过储层岩石学,对XX油田长7储层特征进行深入研究。结果表明,长7层砂岩岩石类型主要为岩屑长石砂岩、长石岩屑砂岩和长石砂岩;填隙物以粘土杂基为主,次为灰泥和白云岩杂基;粒度中值为细砂;分选性中等—差;磨圆度差-极差;孔隙以粒间空隙为主,孔隙度介于4.3%~12.6%,吼道以片状细喉为主。

| Abstract: | The microscopic pore structure of reservoir rock directly reflects the reservoir permeability and provides the important basis of evaluation of reservoir Studying the reservoir characteristics of Chang 7 reservoir XX Oilfield by the reservoir petrology. The results shov, that the Chang 7 sandstone rock types are mainly lithic arkose, feldspathic litharenite and feldspathic sandstone; The main interstitial material is clay, time lbr plaster mud and dolomite mixed; Median size is fine sangstone; Sorting characteristics of medium - poor; Psephicity is poor- very poor; Porosity is given priority to with intergranular space, porosity is between 4.3 %-1 2.6 %.Throat is given priority to with flake fine throat.
