根据地质特征可以将中国近海油气田分为以海相砂岩为主的中小型油田 ,以陆相砂岩为主的大中型常规重质油油田 ,以复杂断块为主 (包括潜山和特殊岩性 )的复杂油气田和大中型砂岩气田等四大类。总结了中国近海不同类型油气田的地质特征 ,并论述了针对不同地质特征油气田所采取的不同开采策略 ,以及实施不同开采策略所取得的良好开发效果和经济效益。
According to the geological characteristics, offshore oil and gas fields in China can be divided into medium and small-sized oil-dominated marine sandstones, and large and medium-sized conventional heavy oil fields dominated by continental sandstone, mainly composed of complex fault blocks (including buried hills and special lithologies ) Complex oil and gas fields and large and medium-sized sandstone gas fields and other four categories. The geological characteristics of different types of oil and gas fields in China offshore are summarized. Different mining strategies for oil and gas fields with different geologic characteristics and good development results and economic benefits obtained through different mining strategies are discussed.
