摘要

摘要: 鲕粒灰岩是重要的碳酸盐岩油气储层。通过常温常压下，北京西山鲕粒灰岩的溶解动力学实验发现，鲕粒灰岩的溶解主要受岩石和矿物的结构和化学成分控制。结构上表现为构造裂缝、鲕粒结合纹、颗粒晶体结合带等结构薄弱带优先发生溶蚀。成分上表现为白云岩化组分不仅自身较易溶蚀，而且能促进鲕粒灰岩的整体溶解；粘土矿物、石英等杂质组分常与鲕粒和白云岩化颗粒伴生，其对两者的阻溶效应更大。溶解过程中，鲕粒灰岩的构造裂隙、鲕粒放射结合纹和同心圈层等首先发生溶蚀，产生溶隙、粒内溶孔和粒间溶孔；其次为白云质组分以及白云质组分与方解石结合处而产生晶间溶孔、粒内溶孔；随着溶蚀强度的加强，围绕鲕粒形成环状溶蚀沟，在鲕粒溶蚀脱落后而形成鲕模孔。

Abstract: Oolitic limestone is an crucial oil reservoir. Through dissolution kinetics experiment under normal temperature and pressure, this paper discussed dissolution kinetics characteristics and morphology evolution of oolitic limestone. The result indicates that oolitic limestone dissolution is main controlled by petrotextural features and chemical composition. Petrotextural feature control is characterized by selective dissolving textural weakness, such as tectonic microfracture, crack in ooid especially oolitic radiate crack, binding domain between grains and crystals and so on. Chemical composition control is characterized by prior dissolution of dolomitized particles and inhabitations of clay mineral and quartz. To dolomitized particles, they not only dissolve easer itself, but also could accelerate rock dissolution. However, to clay mineral and quartz, their inhabitations are more harmful to ooids and dolomitized particles' dissolution than to substrate. During oolitic limestone dissolution, firstly, it brought dissolved crack, intergranular pore, intercrystalliine pore after tectonic microfracture and crack in ooid. Secondly, it led to interpartide pore and intercrystalliine pore with dolomitized particles and calcite around them dissolved. Then, along with further dissolution, annular channel could be formed around ooids. Finally, it would form oolitic moldic pore in surface after ooids fell off substrate.
