【摘要】：元坝长兴组生物礁相储层平面相变快、纵向上多期次叠加,各礁带内小礁体连通性复杂。在实际开发生产中,生物礁体或礁群之间的连通性研究为井位调整优化、井轨迹设计和减少遇水的风险提供了重要依据。目前研究储层静态连通性主要是利用地质综合研究方法或井间地震技术。将频谱成像技术应用于储层静态连通性的研究中,初步形成了一套基于频谱成像技术判定生物礁体或礁群连通性的方法。首先分析井位处生物礁储层与非储层的频谱差异性,然后用这种差异性来指导区域横向上的频谱差异性,进而判定礁体或礁群之间的连通性。利用该方法研究了元坝长兴组各生物礁带的连通性,所取得的认识已初步应用于元坝长兴组气藏开发中,新部署的开发井成功避水,并获得了高产。
[Abstract]:In the Changxing formation of Yuanba formation, the horizontal phase transition of the reef reservoir is fast, the vertical multi-stage superposition, the connectivity of the small reef body in each reef belt is complex. In actual development and production, the research on the connectivity between the reef body and the reef group is to optimize the well location adjustment. The research on static connectivity of reservoir is mainly based on geological comprehensive research method or cross-well seismic technique. The spectral imaging technology is applied to the study of reservoir static connectivity. A method of determining the connectivity of reef body or reef group based on spectrum imaging technique is formed. Firstly, the spectrum difference between reef reservoir and non-reservoir in well location is analyzed, and then the difference is used to guide the horizontal spectrum difference in the region. By using this method, the connectivity of the reef zone in Changxing formation of Yuanba has been studied. The understanding obtained has been applied to the development of Changxing formation gas reservoir in Yuanba, and the newly deployed development well has successfully avoided water. A high yield was obtained.
