摘要:
塔里木盆地顺北油田奥陶系主干断裂带测试获高产油气流,但是断溶体内部规模性储层地震响应特征复杂,需要精细解剖断裂内部结构,从而针对性部署井位。文中首先从现有的钻井、测井资料出发,得出主干断裂带中断裂面附近的空腔洞穴是最优钻探目标;然后在大量井震标定的基础上,总结出空白弱反射、杂乱反射、串珠强反射3类储层的地震响应特征,并指出相干加强属性是一间房组优质储层有效刻画属性;最后针对此类断溶体储层,通过张量属性描述边界,利用不同门槛值的相干加强属性和反演数据,清晰刻画储集体内部结构,形成断溶体储层描述技术。运用该技术,主干断裂带上钻井成功率达100%。
Abstract:
The high oil and gas flow through drilling in the Ordovician main fracture zone of the Shunbei Block of the Tarim Basin has been obtained. However, due to the complex seismic response characteristics of large-scale reservoirs within the fault, it is necessary to precisely dissect the internal structure of the fault and specifically deploy the well. In this article, firstly, based on the existing drilling and logging data, it is concluded that the cavity caverns near the fault planes in the main fault zone are the optimal drilling targets. Secondly, according to a large number of drilling calibration, the seismic response characteristics of weak blank reflection, mixed and disorderly reflection, and string of beads reflection are summarized, and it is pointed out that the coherence enhancement attribute is the effective characterization property of the high-quality reservoir of Yijianfang Formation at present. Finally, for such fault-karst reservoirs, the boundary is described by the tensor attribute, and the combination of different threshold value coherence enhancement attributes and inversion data can clearly describe the internal structure of the type. By using this technology, the drilling success rate on the main fracture can reach 100%.
