塔河油田典型地震相
|
摘要
奥陶系—三叠系是塔河油田的勘探目的层,寒武系—奥陶系的原油沿断裂进入以上各时代的储层中,形成构造、岩性、地层及各种复合油气藏。综合分析三维地震资料与测井、岩心等资料,识别和预测各种沉积相所控制的砂岩和岩溶储层空间展布规律成为塔河油田油气勘探与开发中的一项重要技术。在该区共识别和确定了三叠系的辫状河、曲流河典型地震相,石炭系卡拉沙依组的低弯度河和巴楚组的潟湖—障壁相,泥盆系的三角洲相及奥陶系的岩溶相共六种地震相。三维地震资料的沿层振幅切片、反射强度斜率、波形分类、测井曲线是了解沉积体系格架、骨架砂体和储层展布的主要手段。
Ordovician—Triassic is explored targets in Tahe Oilfield, and crud oil in Cambrian-Ordovician moved into the reservoirs in each above-mentioned layers along the fractures, forming structural, lithologic and various composite oil-gas reservoirs. Comprehensive analysis of 3-D seismic data, logging and core data, identification and prediction of spatial distribution rule of sandstone and karst reservoirs controlled by various sedimentary facies are an important technology in oil-gas exploration and development in Tahe Oilfield. Total six seismic facies are identified in the area, including Triassic typical braid and meandering river; Carboniferous Kalashayi Formation low-sinuosity river and Bachu Formation lagoon-barrier facies; Devonian delta seismic and Ordovician karst facies. The along-horizons amplitude slices in 3-D seismic data, slop of reflection strength, waveform classification and logging traces are main tools in finding depositional framework, sand body and distribution of reservoirs.
