摘　　要：“深地一号”顺北深层油气田项目,位于塔里木盆地腹地,具有超深、高温及高压等特点,储层平均埋藏深度超过7300m,是世界陆上最深的商业开发油气田之一。顺北油气田以“断裂+串珠”形成的断控体为主要勘探目标,储集体空间结构复杂,存在着地震异常体中储层发育的具体位置不能精确预测和定位、实钻资料揭示的储集体特征也与地震预测储集体特征不匹配,目的层压力与应力分布复杂,存在局部高压等诸多问题。这些问题为录井溢流预报带来了很大的困难,也使得安全高效钻井的难度加大。针对以上情况,文章总结顺北区域已钻井录井溢流预报工程参数变化特征,探索顺北工区录井溢流预报工程参数异常模型,该模型在实际应用中取得了较好的成果。“Shendi No.1”-Shunbei deep oil and gas field project is located in the hinterland of the Tarim Basin.It is characterized by ultra-deep,high temperature and high pressure.The average burial depth of the reservoir is more than 7300 meters.It is one of the deepest commercial oil and gas fields on land in the world.Shunbei oil and gas field takes the fault-control body formed by“fault+bead”as the main exploration target.The spatial structure of the reservoir is complex,and the specific location of the reservoir development in the seismic anomaly body cannot be accurately predicted and located.The characteristics of the reservoir revealed by the actual drilling data also do not match the characteristics of the seismic prediction reservoir,the pressure and stress distribution of the target layer is complex,and there are many problems such as local high pressure.As the first responsible person for the overflow monitoring discovery,these problems bring great difficulties to logging overflow prediction,and also make it more diff icult to drill safely and eff iciently.In view of the above situation,the article summarizes the characteristics of parameter changes in the well logging overflow prediction engineering in the Shunbei region,and explores the abnormal parameter model of the well logging overflow prediction engineering in the Shunbei work area.This model has achieved good results in practical application.
