摘　　要：大港高尘头油田歧 1 34- 1断块为 1 995年上报的探明储量区块 ,其目的层为下第三系沙河街组沙三段。该断块由于构造和储层比较复杂 ,一直未能投入开发。近期通过对该断块未动用储量进行评价 ,充分利用各种三维地震资料、钻井、录井、测井、测试与开发动态资料 ,采用先进的三维地震资料处理、构造解释和储层评价技术 ,重新落实了目的层为中生界而非沙三段 ,并新增探明地质储量 2 7× 1 0 4t,新增预测储量 32× 1 0 4t,使中生界成为找油的新领域 ,取得了显著的效果。Qi 134-1 block of Dagang Gaochentou oilfield is an explored reserves block reported in 1995 and its target zone is Sha Ⅲ reservoir of Shahejie oil-bearing group in Eogene. Due to the complicated structure and reservoir, it has not been put into development. Recently undeveloped reserves of the block are evaluated and every kind of 3D seismic,drilling, mud logging, log, well test and production performance data are adequately adopted, what's more, advanced technologies such as 3D seismic data process, structural interpretation and reservoir evaluation are used to reascertain that target zone is Mesoide reservoir not Sha Ⅲ, and explored geological reserves are newly increased by 27×10 4 t and predicted reserves 32×10 4 t, which make Mesoide reservoir a new area to seek for oil and remarkable effect is gained.
