摘要

深南背斜是深县凹陷南部的一个塌陷背斜 ,本区有良好的石油地质条件 ,已发现了一定规模油气藏。由于该区构造复杂 ,地震资料品质较差 ,圈闭落实程度较低 ,已发现的油藏纵向上具含油层位多、油水间互等特点 ,并存在低阻油层 ,影响了勘探开发成效。针对上述勘探中存在的技术难点 ,在工作中应用了高次覆盖三维地震勘探技术 ,提高了地震资料品质 ,并利用新资料理顺断裂结构 ,落实和评价了有效圈闭 ;用定向斜井钻探技术和核磁共振测井解释技术 ,发现了多套含油目的层系 ,提高了低阻油层的认识水平。通过应用综合勘探技术 ,深南背斜油气勘探已取得了进展 ,开发已建立了一定规模产能。
Shennan anticline, a collapse anticline located in the south of Shenxian depression, has good petroleum geological conditions, where sizable reservoirs have been discovered. In this area, the structures are complex, seismic data attributes are poor, trap materialization level is low, the reservoirs discovered have the characteristics of multiple oil - bearing zones with aquifers interbeded, and low resistivity layers exist, thus exploration and development effects are poor. Multifold 3D seismic survey technology is used to improve the quality of seismic data and new data are used to ascertain and evaluate effective traps. The application of directional deviating hole drilling technologies and nuclear magnetic resonance logging technologies lead to the discovery of several sets of oil zones and improvement of knowledge of low resistivity reservoirs.
