摘　　要：加蓬G4-188区块WZ构造带有良好的油气显示,现已从勘探工作阶段转入准开发的关键时期。基于区域地质资料,结合现场地质录井、测井及后期试油等相关资料,对该构造带各层位的油气显示及分布特征进行了总结,探讨了每一层位的含油气特征及区域分布特点。研究表明:PG组为非油气产层;U.PC组为典型的产气层;L.PC组和Anguille组油气显示良好,且地层压力较高,为典型的高压油层。为该区的开发和邻区的进一步勘探提供建议。Oil and gas is abundant in belt WZ of Garbon block G4-188.The focus is moving from exploration to exploitation which is more important.Based on the areal geology data,combining with data of drill program and mudlogging,analyze oil and gas shows and distribution in every position.The results show that PG group isn＇t oil and gas producing formation,U.PC group is typical gas producing formation.L.PC group and Anguille group are typical high pressure reservoirs which have better oil and gas shows and formation pressure is higher.The study provides the reference for the development of this block and the exploration of other blocks.
