Exploration history and revelation of typical complex fault block oilfield

Oil and gas exploration is a gradual process. Liuchu area introduced in this paper is a typical complex small faulted oil bearing block. Its exploration history fully sustain that the essence of success is to insist on determined exploration target. The key to high quality and efficiency exploration is to understand oil and gas accumulation thoroughly, to evaluate comprehensively, and to make plan on full scale. The precondition of success is to perform 3D seismic in time and to define trap accurately. Scientific organization is an important guarantee for improving exploration benefit. An effective way of making further achievement is stereo progressive exploration and development with combination of various data.
