Abstract

Abstract:

A lacustrine carbonate sequence composed of limestone,marl,lime mudstone and gypsiferous mudstone is developed widely in the upper Es⁴ (the 4^th member of the Paleogene Shahejie Fm) and acts as important source rocks in Bonan Sag of northern Huanghe Delta.The source rocks are 20 m to100 m thick with the maximum thickness at Kenxi and Yidong.Rich in sapropel-type organic matters,the rocks are of excellent quality.The source rocks generated hydrocarbon earilier than that of mudstone at the same sequence and reached hydrocarbon generation peak when R_o is about 0.6%.The crude samples show a feature of high homohopane (C₃₅/C₃₄) ratio and high abundance of 4-methylsterane and sulfur content.There were two important stages for oil accumulation:the end of Ed to Ng and the end of Ng to Nm.It is suggested that the carbonates of the upper Es⁴,the fan-delta and beach-bar sandstoneas well as the lower Es⁴ in juxtaposition the oil source rocks in the deep sag,be considered favorable exploration targets.

Key words: timing of hydrocarbon accumulation, exploration potential, hydrocarbon source rock, carbonate rock, Shahejie Formation, Bonan Sag
