摘要
塔里木油田塔北地区目前在碳酸盐岩勘探中面临识别溶洞的真假难、溶洞三维位置确定难以及在长井段裸眼井中电缆VSP测井卡钻风险很高等主要问题和挑战,针对上述问题和挑战,甲方首次在哈16-7井使用随钻地震SVWD和SGD结合综合解决方案。利用SVWD技术在套管井段和长裸眼井段采集准确的时深关系和速度,更新SGD速度模型并对地面地震目标数据进行更新处理,从而对溶孔溶洞的真假以及位置进行准确刻画,进而实时指导钻井钻遇目的体,寻找串珠状缝洞发育,为塔里木油田增储上产提供打下坚实基础。
The tarim oil field in north tarim area in the exploration of carbonate rock face identification of true and false of the karst cave,karst cave it is difficult to determine the three-dimensional position and in a long period of open hole well VSP logging cable stuck drill main problems and challenges,higher risk for these problems and challenges,party a for the first time in 16-7 Wells using seismic SVWD while drilling and SGD combined with integrated solution.SVWD technology is used in cased well and when long open hole section to collect accurate depth relationship and speed,update the SGD velocity model and update the ground seismic data processing,and solution pores of true and false of the karst cave and position accurately,which will guide drilling real-time drill in purpose,looking for beaded seam hole development,on the basis of tarim oil field production to lay a solid foundation.
