渤海南部海域黄河口凹陷新近系油田群具有相同的构造背景和沉积环境,地质条件类似,需要针对影响油田开发的关键问题开展技术攻关,形成一套有效的新近系河流相油田储层预测及描述技术系列.从地震资料入手,针对不同的研究目的对地震资料做相应的目标处理;抓住该区砂岩百分含量低、砂泥岩界面处地震反射特征明显这一特点,优选地球物理技术组合精细刻画储层;在钻前对潜力含油砂体定量描述,并纳入井网规划;最后利用实时可视决策系统对水平井进行实时随钻跟踪,提高水平井钻探效果.从目前已经完钻的开发井来看,取得了很好的效果.

Oil fields lying in south of Bohai Sea and Huanghe River Mouth Sag group Neogene have the same tectonic set-ting and depositional environment. Technology research should be conducted to solve the key problems influencing oil filed de-velopment. A series of technologies including reservoir prediction and description should be developed. From the in-depth study of seismic data, the according target process was done for different research purposes. Fine reservoir characterization was ob-tained by using the preferred geophysical techniques according to the features of low percentage of sandstone and obvious seis-mic reflection characteristics on sandshale interface. Potential oil-bearing sandstone was quantitatively described and classified into the well network planning. At last, real-time track-while-drilling was executed with real-time visualization and decision-making system. Thus, drilling and exploration works were conducted. Field practice shows that the performance of drilled de-velopment wells all achieved good results.
