| 摘 要： | 优质储层发育与分布是深层、超深层碳酸盐岩勘探的关键.近几年四川普光、通南巴和元坝等一系列深层超深层气田的发现,不断在深度上突破早期的认识,探索这类极限条件下优质储层发育机理,成为勘探的热点和难点.本文根据普光气田主要钻井的岩芯观察、薄片、孔渗、电子显微镜、同位素分析等数据资料的分析与统计,探讨普光气田优质碳酸盐岩储层发育的主控因素,提出沉积-成岩环境控制早期孔隙发育、构造-压力耦合控制裂缝与溶蚀、流体-岩石相互作用控制深部溶蚀与孔隙的保存的"三元控储"机理.

| Abstract: | The formation and distribution of high quality reservoirs are key to the prospecting in deep marine carbonates. In recent years, the discoveries in (ultra-) deep-buried carbonate reservoirs of the giant Puguang gas field and many others have broken through the early viewpoints. The formation mechanism of this kind of reservoirs under the limited conditions has become the highlight, as well as the nodus of researches. Based on the petrological characteristics from drilling cores and thinsections, and data from porosities, permeabilities, and isotopes, three controlling factors are summarized: (1) the early depositional and diagenetic environment which controlled the early porosities; (2) tectonics and formation pressures which formed the fractures and dissolutions; and (3) fluid-rock interactions that influenced the deep burial dissolution and the preservation of the porosities. |
