| 摘 要： | 为了预测松辽盆地深部碎屑岩成岩阶段和次生孔隙发育带的展布、研究储层孔隙发育史与其他成藏要素的匹配关系，本文将传统的成岩作用研究和数值模拟技术相结合，在作用模型和效应模型的基础上，建立了一个成岩作用数值模拟的综合模型。松辽盆地升平地区深层登娄库组成岩演化的研究表明，在泉头期末，登娄库组进入晚成岩阶段A1期，烃源岩进入生油门限，储层开始发育次生孔隙；在青山口期末，登娄库组处于晚成岩阶段A—B期，登二段烃源岩进入大量生、排烃的成熟阶段，生烃时间、储层次生孔隙发育时间和圈闭形成时间匹配良好，油气藏开始形成。目前，本区的登娄库组在南部主要处于晚成岩阶段C期，在北部处于晚成岩阶段B期。成岩指数ID=0．85～1.15，且有砂体发育的地区，即为本区次生孔隙发育带的分布范围。 |

| Abstract: | In order to predict the distribution of the diagenetic stages and the secondary pore zones in the deep of the Songliao basin and to study the matching relationships between the pore developing history and the other oil reservoir forming elements, we combined the clastic diagenetic theory with numerical modeling and established an integrated model for modeling diagenesis and predicting secondary pore zones on the base of effect-oriented models and process-oriented models. As the modeling results of the Shengping area of the Songliao basin show, at the end of the Quantou age, the Denglouku Formation got into the late diagenetic stage A1,in which the source rocks penetrated the petroleum-generation threshold and the reservoir rocks began to form secondary pores. At the end of the Qingshankou age, the Denglouku Formation reached the late diagenetic stage A-B, in which the source rocks were located in the mature stage and generated enormous petroleum, the reservoir rock secondary pore formation and the trap development matched well, and the oil and gas reservoirs began to form. Today the Denglouku Formation is situated in the late diagenetic stage C in the southern Shengping area, but in the late diagenetic stage B in the northern Shengping area. Where ID equals 0. 85~1. 15 and there exist sandstone bodies, there are secondary pore zones of reservoir rock. |
