运用油层水矿化度、变质系数和还原系数等参数对本区长6油层流体运移聚集成藏特征进行了初步研究，研究结果表明油层水化学特征所反映的油气运移成藏规律与勘探开发取得的实际认识相一致。长6油层虽然埋藏浅，但是并没有受到地表渗入水的影响，完整的保存了地层水原始特征。根据研究成果对研究区内油气运移聚集成藏有利区进行了预测，探索油层水化学特征在深化油田勘探开发方面的可行性。“,”Fluid migration,accumulation and preservation in Chang 6 oil-bearing formation are researched from the mineralization,metamorphic coefficient and reduction coefficient.Research results show that oil and gas migration accumulation reflected by the reservoir water chemical characteristics is in line with exploration and development.The Chang 6 oil-bearing formation is shal ow depth,not affected by the surface infiltration water and complete preserved the original formation water feature. According to the research results,the favorable area for hydrocarbon migration and accumulation is forecasted.Explore the feasibility in deepening the oil field exploration and development of the reservoir water chemical characteristics.
