摘　　要：渤海湾盆地黄骅坳陷南堡凹陷周边唐180×2井在寒武系碳酸盐岩测试获日产260 m3工业油流,揭示了寒武系碳酸盐岩良好的油气勘探前景。但由于该层系勘探程度低,钻井少等因素,碳酸盐岩储层研究不深入,已成为该区油气勘探突破的瓶颈问题。综合研究表明,寒武系碳酸盐岩是受多旋回构造运动、多期岩溶及成岩作用控制的缝洞复合储集体,发育溶蚀孔洞型、裂缝-孔隙型、孔隙型及裂缝型共四种储集空间类型。溶蚀孔洞及裂缝-孔隙型储集物性较好,主要分布在寒武系中统、下统的渗流岩溶带及潜流岩溶带,为该区下步油气勘探部署的重要层位。Good industrial oil flows of daily oil production 260 m3 has been acquired from 180x2 wells in carbonate rocks of Nanpu depression,Huanghua depression and surrounding the Cambrian system,which reveals the Cambrian carbonate is of good oil and gas exploration prospect.However,because of low degree of prospecting and less drilling data,the research on carbonate rock reservoir has not deep yet,and it has become a bottleneck problem of the oil and gas exploration breakthrough.Through comprehensive studies,the results show Cambrian carbonate rocks are polycyclic tectonic movement of karst,multiphase and diagenesis control seam hole composite reservoir,solution pores,cracks and porosity,pore type and fracture type,a total of four types of reservoir space have been well developed.Solution pores,fractures and pore type reservoir are of better properties,which are mainly distributed in seepage in karst belt and undercurrent karst belt of the lower-middle Cambrian,which provides important horizon for the next deployment of oil and gas exploration.
