冀中地区文安斜坡带成藏特征研究

斜坡带的重新认识对油田的稳定发展越来越重要。通过对文安斜坡带生油洼槽的生油条件、油气运移聚集规律、成藏特征研究后认为：文安斜坡带具有充足的油源，是油气运移的必然指向，但其总体勘探开发程度相对较低，仍具有较大的滚动勘探开发潜力；同时，圈闭形成与油气大规模运移期具有良好的配置关系，具备形成大中型岩性油气藏的物质基础。及时总结文安斜坡的成藏条件、基本成藏规律以及勘探开发成效，对斜坡带的研究以及提高油田勘探开发综合效益，具有重要的指导和借鉴意义。

Accumulation characteristics in Wen'an slope belt in Jizhong Depression

The hydrocarbon generation conditions and migration and accumulation characteristics in Wen＇ an slope are studied. The result shows that Wen＇an slope has abundant oil sources, it is favorable for indicating the oil and gas migration, and now it is believed to have great prospecting potential. Trap forming has a close relationship with hydrocarbon migration and oil sources are sufficient, which settled a strong base for the forming of lithologic reservoirs. The analyses of the hydrocarbon accumulation conditions and characteristics in Wen＇an slope belt are beneficial to the research of slope belt and take a significant part in guiding the further development in Huabei Oilfield.
