伏龙泉地区泉一段精细构造解释与有利目标评价
|
摘要
根据勘探和开发的需要,对伏龙泉地区主要目的层(泉一段)进行精细构造解释和有利目标评价。精细构造解释依据高分辨率、高保真和高信噪比的地震数据体,运用Landmark人机联作软件,对目的层进行井-震标定,确定目的层段的地震反射相位和地震波组特征,并在工区内其它井信息的辅助下开展横向追踪,用变速成图的方法绘制目的层段的构造图,落实各目的层的圈闭。在构造解释的基础上利用相干技术和时间切片辅助进行断层识别,并结合相关石油地质资料对目的层进行综合评价,优选出有利的油气圈闭,为勘探开发提供目标。
For the needs of exploration and development,the main target layer(Quanyiduan) in the Fulongquan region is interpreted in the fine structure and the favorable target is evaluated.Fine structural interpretation is based on high-resolution,high fidelity and high signal to noise ratio of seismic data,the use of Landmark Interaction software layer is to locate the well-seismic calibration of the target layer so as to determine the seismic reflection and seismic wave group characteristics of the target layer phase.And also other work is carried out with the help of the information in other wells.In the structural interpretation based on the use of the related technique and time slice for fault identification,combined with relevant geological and oil data on the target layer,the comprehensive evaluation is made.Good oil and gas traps are selected,which is helpful to the exploration and development.
