高精度三维地震在马王庙地区隐蔽油藏勘探中的应用

The Application of Three Dimensional Seismic Prospecting Methods with High Precision in Mawangmiao Subtle Reservoirs Exploration

江汉盆地马王庙地区已进入隐蔽油藏勘探阶段,因此进行了马王庙地区高精度三维地震勘探部署。利用方差体、三维可视化等解释技术,提高了在该地区解释精度,对该地区的结构构造、断裂特征、储层预测及圈闭识别方面有了新认识,同时形成了高精度三维地震在隐蔽油藏勘探中应用的新技术,在油气勘探中获得了较好的应用效果。

Three dimensional seismic prospecting methods with high precision were deployed in Mawangmiao of Jianghan Depression for the drilling project there had entered the phase of subtle reservoirs exploration.Interpretation skills such as variance cube and three-dimensional visualization techniques had been applied to improve the accuracy of interpretation which led to new understanding of composition,fracture characteristics,reservoir forecast and trap identification in the area while the newly developed techniques to employ three dimensional seismic prospecting methods with high precision in elusive reservoir exploration had achieved fairly good feedbacks.
