摘要

卫城—古云集地区沙一中油藏因构造复杂,储层发育规律认识不清,一直未得到有效开发。通过建立对比剖面,精细地层对比,根据三维地震和钻井资料,结合测井曲线,应用多方向油藏剖面技术开展构造精细解释研究,并进行储层评价,进一步落实构造,认识储层。开展了水平井优化部署研究,重点对水平井的位置、井身轨迹方位及水平段长进行优化。在此基础上,在沙一中油藏有利部位部署并实施了3口水平井,取得了明显效果,为薄油层油藏的成功开发开辟了新的途径。
Because the reservoir structure is very complex and the reservoir development law has not been clearly understood in the middle part of the first member of Shahejie Formation in Weicheng-Guyunji Area,it hasn't been effectively developed. By establishing the correlation section and making the detailed stratigraphic correlation,the detailed structure explanation has been conducted and the reservoir evaluation has also implemented through using the three dimensional seismic data,drilling data,well log curves and applying the multi-direction reservoir section technology. The optimizing disposition of horizontal well has been developed. The horizontal well location,wellbore trajectory and the length of horizontal well section are stressly optimized. Based on the above,three horizontal wells have been located in the available position of middle Es1 reservoir. The better effect has been obtained at present,which opens a new way for the development of thin reservoirs.
