摘要(Abstract)：

松辽盆地敖南地区构造较为简单,速度横向变化小,为了节省投资,该区的斜直井钻井比例为3∶1,开发井完钻后,需要根据完钻井的深度对构造图进行校正。构造图作为一个地质基础图件,在预探阶段、评价阶段及开发阶段都发挥着重要的作用,构造的准确与否对滚动开发,尤其是水平井钻井工作关系重大。利用部分直井作为校验井,通过分析斜直井校正对构造成图精度的影响,得出合理的构造校正方法,为水平井钻井和滚动开发提供指导。
The structure of Aonan region in Songliao Basin is not so complicated and the horizontal change of velocity is not obvious,hence to save operation cost,the deviated well and straight well ratio is designed to be 3:1 and after the completion of development wells,structural maps would be corrected according to the depth of drilled wells.Structural maps are the foundation of exploration works,which play an important role in preparatory exploration stage,evaluation stage and development stage.The precision of structural maps directly correlates to the effect of development and horizontal well drilling.In this article,it is proposed to take some of the straight wells as check wells to analyze the influences of deviated well and straight well correction on structural maps precision in order to get the most reasonable way for structural correction,and thus providing guidance for horizontal well drilling and development of the western periphery regions.
