油田成藏条件及勘探开发关键技术分析

Analysis of Reservoir Formation Conditions and Key Technologies for Oilfield Exploration and Development

针对目前特殊地质条件下是否具备油田成藏条件、是否具备勘探、开发技术条件等理论技术缺失,现在特殊地质条件下油田勘探和开发的现状。以鄂尔多斯盆地特殊地质条件为基础,对其成藏条件、勘探方案、抽采方案等进行了分析。结果表明,在盆地条件下黑色页岩具备最强的生烃能力,采用井-震混采及单点接收的三维地震采集技术方案能够实现对特殊地质条件下的精确勘探,采用水力喷砂分段压裂工艺技术能够实现在特殊地形条件下的高效开采。

In view of the lack of theories and technologies such as whether oilfield formation conditions and exploration and development technology conditions are available under special geological conditions,the current status of oilfield exploration and development under special geological conditions.Based on the special geological conditions of Ordos Basin,the reservoir formation conditions,exploration plan and extraction plan are analyzed.The results show that the black shale has the strongest hydrocarbon production capacity under the basin conditions,and the 3D seismic acquisition technology of well-seismic mixing and single-point reception can achieve accurate exploration under the special geological conditions,and the hydraulic sandblasting segmental fracturing technology can achieve efficient extraction under the special topographic conditions.
