摘要

东海平湖油气田某油藏有3类原油,各类原油有显著的特征参数,经过筛选,芳烃的δ13C可作为原油的标记指纹.在油藏内原油自西南向东北运移,并且也可从下部H6储层向上运移至H2储层中,运移主要受构造隆起控制.油藏的连通性良好,成藏后虽有脱沥青作用影响,但不是很强,对储层的损伤影响较小,仍保持较好的连通性.

Abstract

There are three different types of crude oil in reservoirs of Pinghu oilfield. The oil can be discriminated by obvious geochemical parameters with carbon isotope of aromatic hydrocarbon as the fingerprint marker. The oil was migrated from southwest to northeast and from reservoir H6 in the lower part to reservoir H2 in the top. And hydrocarbon migration was controlled by structural uplift. The reservoirs were well connected, although the light deasphalted action of oil blocked some pores of reservoirs.
