岩性圈闭综合预测技术在油气勘探中的应用

Application of Comprehensive Forecast of Lithological Traps in Hydrocarbon Exploration

运用沉积相、测井地质学、地震信息储层预测等方法和技术,结合地震、测井信息及地质资料,建立地震相、测井相和沉积相的关系,摸清砂岩成因及分布规律是建立预测岩性圈闭模型,指导油田勘探的有效途径。实践表明,该项技术在油气勘探中取得了较好的应用效果。新发现莱10-斜7、莱2南、广2南等5个岩性圈闭,提供可钻探井位4口,完成探井2口,新增探明石油地质储量62×104t。

t is an effective way of building models for forecasting lithological traps and guiding hydrocarbon exploration that we ascertain the relations among seismic facies, logging phase and sedimentary facies as well as sandstone causes and distribution laws by means of sedimentary facies, logging geology and earthquake information reservoir forecast in accordance with earthquake, logging information and geological data. Practice proves this technology has a better effect in oil and gas exploration. The five lithological traps, which was newly discovered, supply 4 drillable well locations and 2 exploration wells and bring out proved petroleum geological reserves of 62 × 10^4 t.
