摘要:

地应力对深层-超深层致密砂岩储集层品质控制明显,厘清应力控储效应对深层-超深层致密砂岩储集层综合评价与预测至关重要。通过岩心、薄片等分析化验资料揭示了库车坳陷中秋地区白垩系巴什基奇克组储集层基本特征,实现了地应力大小测井评价,并阐明地应力对储集层品质控制。结果表明,储集层岩性主要为中细砂岩,以原生粒间孔隙为主,次生孔隙较少,偶尔可见裂缝。通过成像测井实现了裂缝面形态拾取,同时实现了裂缝参数测井计算,在此基础上通过测井资料完成了地应力大小评价,并揭示了地应力对基质孔隙及裂缝参数耦合控制关系。综合物性参数以及地应力大小实现了巴什基奇克组储集层分类评价,优质储集层主要发育在裂缝发育段以及低水平两向应力差区域。通过地应力测井评价结合储集层参数计算,可实现储集层品质分类评价以及优质储集层测井预测。研究成果可为深层-超深层致密砂岩储集层综合评价与有利区带预测提供技术支撑。

Abstract:

In situ stress significantly controls the quality of deep and ultra-deep tight sandstone reservoirs. It is important to clarify the stress-controlled storage effect for the comprehensive evaluation and prediction of deep and ultra-deep tight sandstone reservoirs. In this paper,basic characteristics of the Cretaceous Bashijiqike Formation in the Zhongqiu area of Kuqa Depression are revealed through analysis of cores and thin sections,the logging evaluation of in situ stress is realized,and the control of in situ stress on reservoir quality is clarified. The results show that the reservoir is mainly made of medium-fine sandstones,which is dominated by primary intergranular pores,with less secondary pores and occasional fractures. The fracture surface morphology is picked up by image logging,and the logging calculation of fracture parameters is realized. Evaluation of in situ stress is completed through logging data,and the coupling control relationships between in situ stress,and matrix pores and fracture parameters are revealed. The reservoir classification and evaluation of the Bashijiqike Formation are realized by combining physical parameters with in situ stress. High-quality reservoirs are mainly developed in fractured zones and intervals with low in situ horizontal stress differences. Through logging evaluation of in situ stress combined with calculation of reservoir parameter,the reservoir quality classification evaluation and high-quality reservoir logging prediction can be realized. The research results may provide technical support for the comprehensive evaluation of deep and ultra-deep tight sandstone reservoirs and the prediction of favorable zones.

Key words: deep and ultra-deep reservoir, in-situ stress, reservoir quality, Bashijiqike Formation, Zhongqiu area, Kuqa Depression, Tarim Basin
