随机模拟地震反演技术在水平井井位设计中的应用

Stochastic Simulation of Seismic Inversion Technology in the Design of Horizontal Wells Application

摘要: 随机模拟地震反演技术是储层预测中一项比较实用的技术，该技术算法稳定、可靠、精确，在储层描述方面有较强的优势，尤其对构造及储层复杂地区的预测效果更加明显。大庆长垣东部Z201地区扶余油层储层物性差，横向上属于典型的砂泥岩薄互层，平面迭加连片，油水和岩性分布复杂，地震预测难，本文运用该项技术进行储层预测和精细描述，预测效果与钻井数据吻合度较高，与区域沉积特征吻合，为该区的水平井井位设计提供了可靠的依据。

Abstract: Stochastic modeling of seismic inversion in reservoir prediction technology is a more practical technology, which algorithm is stable, reliable, accurate, description of the reservoir has a strong advantage, especially in complex areas of construction and reservoir prediction was more obvious. Of Daqing area in eastern Z201 poor reservoir properties of Fuyu oil layer, typical laterally interbedded shale, thin, flat lace overlay, complex distribution of water and lithology, seismic prediction is difficult, the use of the technology for this reservoir prediction and fine description, prediction results and drilling material coincide degrees higher, consistent with the regional sedimentary characteristics, the area of the horizontal wells provide a reliable basis for design.
