摘要
对沙花瓦地区的测井、测试、岩石物性等资料分析发现,沙埝、花瓦内坡带存在超压封存箱,其平面分布范围受到穿插火成岩和边界大断层的影响,纵向上盐城组沉积厚度的差异掩盖了超压封存箱的发育深度的一致性。封存箱内阜一段储层虽然埋深大,但是由于存在异常高压,其物性较好,产液能力强,而且箱内烃源岩排烃能力强,从而导致该区带油气显示丰富,具备形成富集油藏的成藏条件。
According to data analysis of logging,testing and physical properties,it was found the overpressure compartments in the inner slope belt of the Hua- Sha- Wa area. Their distributions in plane were affected by igneous rocks and boundary faults. The differences of Yancheng sedimentary thickness covered the consistency of the development depth of the overpressure compartment. Due to abnomal high pressure,better physical properties,higher fluid production ability,and stronger the hydrocarbon expulsion capability of source rocks in the overpressure compartment,which leads to enriched oil- gas shows,the first member of Funing Formation has the conditions of hydrocarbon accumulation.
