摘　　要：鄂尔多斯盆地一直是中国油气勘探开发的重点地区之一,发现了一批重要的油气田。随着勘探程度提高,勘探对象转向致密、深层及盆地周边等成藏条件复杂区,寻找新的整装规模储量难度不断增大。通过系统总结近年来长庆油田公司在致密砂岩气和海相碳酸盐岩天然气等领域取得的新认识和新进展,分析了盆地不同类型气藏的主要地质特征和控制因素,结合油气资源分布状况和新发现气藏基本特征,科学地提出了油田公司“两步走”的发展战略,并指出了碳酸盐岩天然气、致密砂岩气以及除致密砂岩气以外的非常规天然气未来的勘探接替领域。同时针对勘探开发过程中面临的问题,紧密结合生产实践,系统制定了相应的工作对策。通过强化地质研究、积极转变工作思路,加大技术攻关.推进勘探开发一体化、地质工程一体化进程,以实现天然气的规模有效勘探开发,为其他类似盆地勘探和开发提供经验和借鉴。The Ordos Basin has always been one of the key oil&gas exploration and development areas in China.And in the Ordos Basin,some important oil and gas fields have been discovered.As the exploration continues,the exploration objects turn to the areas with complex hydrocarbon accumulation conditions,e.g.tight zones,deep zones and basin peripheries,and the difficulty in searching for new large-scale monoblock reserves increases.The Changqing Oilfield Company’s new cognitions and progresses in the fields of tight sandstone gas and marine carbonate gas in recent years were summarized systematically,and the main geological characteristics and control factors of different types of gas reservoirs in the Ordos Basin were analyzed.Then,based on the distribution situations of oil and gas resources and the basic characteristics of newly discovered gas reservoirs,the“two-step”development strategy of Changqing Oilfield Company was put forward scientifically.In addition,the future exploration replacement fields of carbonate gas,tight sandstone gas and unconventional natural gas(tight sandstone gas excluded)were pointed out.Finally,in view of the problems in the process of exploration and development,the corresponding countermeasures were formulated systematically by combining with production practice closely.In this way,the geologic researches are strengthened,the working concept is transformed actively,the technical researches were reinforced and the exploration-development integration and the geology-engineering integration are promoted so as to realize the large-scale efficient exploration and development of natural gas and provide the experience and reference for the exploration and development of similar basins.
