摘要
对辽河油田笔架岭地区油藏特征及控制因素进行的研究结果表明 ,在辽河油田笔架岭地区的沙二段至东三段沉积时期 ,发育了受西侧物源供给影响的扇三角洲和辫状河三角洲前缘砂体。这些砂体临近东侧的海南生油洼陷 ,具有中等至低的成分和结构成熟度 ,并具有原生和次生孔隙混合发育的储集空间和中孔、中低渗的储层物性。此砂体在向东撒开的帚状断裂控制下 ,形成了断块型油气藏。这些油气藏的分布受控于断裂活动及其展布。断块油气藏呈屋脊状并沿二级主干断层上升盘多层位分布。根据目前油气分布状况和断裂油气藏特征 ,预测了 5个有利的油气勘探地区。
During the deposition period of Shahejie formation in the Tertiary, fan delta and braided delta in influence of western material supply were developed. These sand bodies of delta were near to Hainan source area. They had mid lower maturity in composition and texture, and had the primary and second pores, as well as mid porosity and mid lower permeability in the reservoir quality. Faulted pools were controlled by fault activity and distribution. They occurred along the up throw of growth faults lastly. Five favorite targets had been forecasted on the basis of present hydrocarbon occurrence and characteristics of faulted pools.
