南堡凹陷高柳地区深层储层特征及影响因素分析

Deep reservoir characteristics and its controlling factors at Gaoliu area,Nanpu depression

  • 摘要: 南堡凹陷高柳地区深层沙河街组储层主要为低孔、低渗-特低渗储层,孔隙度一般在3%~18%之间,渗透率多在(0.1~100)×10~(-3)μm~2。深层孔隙类型主要包括粒间溶孔、粒内溶蚀孔、铸模孔、溶解填隙物内孔隙和溶解缝。深层储层影响因素主要包括成岩作用和异常压力。淡水淋漓溶蚀作用导致深层砂岩在3 250~3 800 m形成一个次生孔隙发育带。断层和不整合面作为淡水的淋滤通道,与异常高压等因素一起控制着次生孔隙的分布,据此预测,高柳地区高北断层附近、朔河断层下降盘、唐海地区、紧靠柏各庄断层下降盘的拾场次凹是深层储集层物性较好地区。

     

    Abstract: The deep Shahejie formation consists of low porosity and low to extremely low permeability sandstones at Gaoliu area,Nanpu depression.The porosity is 3%-18%and the permeability as(0.1-100)×10~(-3)μm~2,The porosities in deep horizon include the secondary intraparticle porosity,the interparticle porosity,the moldic porosity,and the dissolved cement porosity and fractures.Controlling factors of deep horizon reservoir include diagenesis and abnormal pressure. Severe dissolution generates a secondary porosity interval between 3 250 m and 3 800 m.Faults and uncomformities, served as the leaching path of ground water,alone with the abnormal high pressure,is a key factor to the secondary porosities distribution.Superior reservoirs are possibly in the places near the Gaobei fault,the footwall of Shuohe fault, Tanghai area,and Shichang sub-depression near the foot-wall of the Baigezhuang faults.
