【摘要】：元坝长兴组生物礁储层纵向上多期次叠加,内幕结构十分复杂,精细雕刻难度大。在实际开发生产中研究生物礁内幕结构可为井位调整优化和井轨迹设计钻遇优质储层提供重要依据。通过单井相识别生物礁发育层段、地震模型正演建立地震响应模式、古地貌分析、地震属性优选、储层多参数定量预测进行礁平面展布研究,并应用三维可视化技术对礁体内幕精细雕刻,形成了一套针对生物礁储层内幕结构的精细雕刻技术。应用该技术对元坝长兴组生物礁储层进行开发井位部署及井位优化调整,大大提高了优质储层的钻遇率,后期钻井预测厚度的符合率达88.6%。
[Abstract]:The reservoir of the Changxing formation of Yuanba is superimposed for many times in longitudinal direction. The inside structure is very complicated and the fine carving is difficult. The study of the inside structure of the reef in actual development and production can provide an important basis for well location adjustment optimization and well trajectory design in drilling for high quality reservoirs. The seismic response model, paleogeomorphology analysis, seismic attribute optimization and reservoir multi-parameter quantitative prediction are used to study the reef plane distribution through single well facies identification of the reef developed zone, seismic model forward modeling, paleogeomorphology analysis, seismic attribute optimization and reservoir multi-parameter quantitative prediction. A set of fine engraving techniques for the inside structure of the reef reservoir is formed by using the 3D visualization technology to carve the curtain of the reef body. The application of this technique to the development of the reef reservoir in Changxing formation of Yuanba and its optimization and adjustment have greatly improved the drilling rate of the high quality reservoir, and the coincidence rate of the predicted thickness of drilling in the later stage is up to 88.6.
