Research on quantitative description of new source rocks-old reservoir rocks vertical filling in eastern Sha-4 member of southern slope,Dongying depression

Hydrocarbon vertical filling is an important new source rocks-old reservoir rocks hydrocarbon accumulation pattern in structural depression zone.Aiming at eastern Sha-4member of southern slope in Dongying depression,the vertical filling of Sha-4 upper member source rock on Sha-4lower member reservoir rock has been studied.By applying the statistical method,the research on the relation between formation pressure coefficient and hydrocarbon shows thickness has been carried out.With the acoustic logging method,the abnormal formation pressure and the vertical filling depth have been calculated,the vertical plane distribution range have been further studied,the pressure-controlled reservoir characteristics of hydrocarbon pressure have been determined,and the favorable exploration direction has been made clear,and the quantitative description method of hydrocarbon vertical filling has been formed,which provides goodreference for hydrocarbon accumulation of similar new source rocks-old reservoir rocks type.
