叠后波阻抗约束反演的若干问题

Some Questions of Constraint Inversion of Post-Stack Wave Impedence

油气勘探已由构造油藏转向隐蔽油藏,储层预测与描述是隐蔽油藏勘探的关键,现在发展起来的叠后波阻抗反演是综合地质、钻井、测井和地震等资料预测描述油气藏的一种行之有效的方法,而地质、钻井、测井和地震等基础资料品质的好坏直接关系到反演精度,通过实际应用,谈及合成记录、地震子波、层位追踪等对其应用精度的影响。

The exploration had turn from structure reservoir to concealed reservoir,the key of concealed treservoir exploration is the prediction and discription.The developed poststack impedance invertion is good way for reservoir prediction and discription combined with geology,drilling,logging and seismic data.But the quality of geology,drilling,logging and seismic directly affect the accuracy of invertion.Through the application,the article talk about the affection of synthetic,wavelet and horizon about the accuracy of invertion.
