东营凹陷陈官庄地区构造精细研究
|
摘要
东营凹陷陈官庄地区在2005年以前使用老的三维资料,分辨率低,不能满足勘探开发需要;2004—2005年对该区进行高精度三维资料采集。在高精度地震资料采集、处理基础上,运用相干、可视化等技术手段,完成了研究区多个地震反射标准层构造解释和非标准层储层预测,确定了该区的断裂体系、储层分布、油气成藏的控制作用,新发现控制含油圈闭8个,圈闭面积为21.3km2。根据地质综合研究成果,取得了良好的应用效果,在官126、官14、王66、王661、王73等区块部署钻井29口,2007年上报沙四段含油面积23.81km2,控制石油地质储量908.48×104t;新建产能10.82×104t。
The old 3-D data ever used in the Chenguanzhuang area before 2005 feature in low resolution and can not meet the requirement of exploration and development. During 2004 and 2005,high-accuracy 3-D data acquisition was conducted in the area. On the basis of high-accuracy seismic data acquisition and processing,using such techniques as the coherence technique and the visualization technique,structural interpretation of marked seismic reflection zones and reservoir prediction of unmarked zones are fulfilled in the area. The control effect on fracture system,reservoir distribution,oil and gas accumulation is determined. Eight controlled petroliferous traps are newly discovered,with the petroliferous area of 21.3km2. According to the comprehensive geological research results,good application results are obtained. 29 wells are deployed in some blocks,such as the Guan 126 block,the Wang 66 block,the Wang 661 block,and the Wang 73 block. In2007,the petroliferous area of Es4 was reported as 23.81 km2,the controlled oil in place was 908.48×104t,and the improved productivity was 10.82×104t.
