孤东地区浅层声波曲线分析与校正

Analysis and correction on acoustic logging curve in shallow formations of Gudong area.

钻井过程中 ,泥浆滤液可使浅层较疏松岩层井壁发生垮塌 ,形成侵入带 ,造成声波测井曲线失真 ,进而影响由此合成的地震记录与实际地震剖面的相关对比。该文根据实测井径资料 ,提出了浅层声波测井曲线校正方法。该方法在孤东 2

Because of the loose sand in shallow formations, the soak of mud filtrate in drilling leads to the sidewall collapse forming invaded zone. It results in the falsification on acoustic logging curves, which has effect on the correlation between composite seismogram and actual seismic section. A method of correcting shallow acoustic logging curves is introduced on the basis of data of caliper survey achieving good results in Gudong 281 well block.
