摘要/Abstract

摘要： SAGD开发效果对储层非均质性十分敏感，泥页岩夹层对双水平井SAGD的泄油通道有一定的影响。以新疆风城某SAGD区块为研究目标区，建立了表征注采井间及井对上方夹层的多因素油藏数模模型，分别模拟了不同夹层展布形态、水平及垂向位置下的SAGD开发效果并进行对比研究，得到了夹层非均质油藏SAGD部署的临界夹层展布形态特征参数。同时可通过产油曲线所展现的典型特征，反推出诸如泥页岩夹层长度以及垂向位置等夹层展布情况，从而进一步掌握目标层系的地质体系结构，对指导下一步双水平井SAGD部署，规避地质风险，实现SAGD高效开发具有重要指导意义。

Abstract: SAGD performance is very sensitive to reservoir heterogeneity, and shale interlayers have a certain effect on a SAGD drainage channel with dual horizontal wells. Based on research of the Xinjiang Fengcheng oilfield, the multiple-factors numerical model characterizing a reservoir with interlayers between or above an injector-producer was established, and the SAGD performances were simulated under different interlayer distributions and horizontal and vertical locations to obtain the threshold parameters. In addition, the oil production profiles were used to detect geological architectures such as the size and the vertical location of shale barriers and act as a guide to enhance well deployment and avoid geological risk, thereby providing significant guidance for the realization of a SAGD-efficient development.

Key words: shale interlayer, SAGD, steam chamber development, oil rate curve, interlayer distribution
