一体化地震勘探技术在孔雀河斜坡地区的应用
|
摘要
孔雀河斜坡位于塔里木盆地的东北部,该区具有良好的油气勘探前景,但地震地质条件十分复杂,曾经经历了几个阶段的勘探,均未获得突破。在新一轮勘探中,运用基于地质目标的采集方案设计、交互地震资料处理、地震地质资料综合解释的一体化勘探技术,以提高勘探精度。通过第一轮一体化地震勘探,在该区发现和落实圈闭20个,并在维马2号断背斜上钻探了孔雀1井,中途测试获商业油气流,实现了当年勘探、当年初见成效的良好局面。
Kongquehe slope is situates in the northeast of Tarim basin,which has good oil/gas exploration prospect,but it has complex seismic and geologic conditions which resulted in unsuccessful explorations many times in the past.In a new round of exploration,we adopted integrative exploration techniques such as geologic targets oriented acquisition scheme design,interactive seismic data processing and integrative interpretation of seismic and geologic data to improve exploration accuracy.After first round of integrative seismic exploration,20 traps have been found and determined and Kongque 1 well in Weima 2 faulted anticline has been drilled,the commercial oil/gas stream has been gained in well test,achieved in good scenario that the exploration provided benefits the same year it was finished.
