Guan010-X1井分层失误原因分析

Cause Analysis of Failure in Stratification of Well Guan010-X1

Guan010-X1井在钻井过程中的地质分层与地震资料预测的地层深度出现较大误差时,运用测井资料,结合地质录井岩性资料能准确地确定地层深度,通过邻近资料的对比,分析Guan010-X1井地质分层出错的原因,指出了地质分层在实钻过程中的重要性。

In drilling process of well Guan010-X1, it is found that there is a big error between the geologic stratification and the formation depth predicted by seismic data. The formation depth was accurately determined using wireline logging curves and the lithologic characters of the geologic mud-logging, the causes leading to the stratification failure of well Guan010-X1 are analyzed by comparing with the formation of a adjacent well, and the importance of geological stratification in the process of drilling is pointed out.
