摘要

以“三结合”为基础,建立了本研究区碳酸盐岩裂缝性气藏模式。该模式对本区二、三叠系裂缝性气藏的构造发展与演化配置关系、构造裂缝与油气成藏关系、储集体成藏机理与成藏关系进行了全面系统的“三分析”,归纳出十项成藏规律。利用这一模式对本区钻探井进行钻探效果和气藏压力预测,符合程度高。本模式可用来预测有利构造带和局部构造,优选钻探目标,提高勘探成功率。指出了利用本模式仍然存在勘探风险,需要地质、地震专家通力合作确定钻探具体目标。
A model of fractured gas pools is proposed and established for the carbonate rocks in this studied area on the basis of combining the developing patterns of fractures,the seismic prospecting and the practical exploration results.In this model,the Permian and Triassic fractured pools of this area are analysizecl in three aspects,called tree analyses,i.e.analyses of the disposing relationships between structures and hydrocarbon evolution, between structural fractures and hydrocarbon reservoir formation and between mechanism of reservoir formtion and pool formation,which are then summarized into ten rules of reservoir formation.This model has been applied to predictions of the drilling results and the gas pool pressures in the drilled wells in this area and has indicated in accordance with the facts. It is suggested that the model may be used to the prediction of structural belts and local structures.
