综合利用岩石薄片、储层物性等资料，结合埋藏史及油气充注史研究，通过分析成藏期毯砂成岩特征，建立成岩演化序列与油气充注的对应关系，并分别采用压实趋势法与反演回剥法对准噶尔盆地中部1区块侏罗系三工河组二段下亚段[ J1 s2（1）]毯砂在关键成藏期的孔隙度进行了定量恢复。结果表明，在成藏关键期，毯砂埋藏浅，物性较好，可做为较好的油气输导层及储集层，表明该毯砂在成藏关键期的重要输导作用，同时明确了该区具有较大的勘探潜力。

By using thin section and physical property data and in combination with the burial history and hydrocarbon charging history , this paper studied the diagenetic characteristics of the blanket sand in the hydrocarbon charging period , and established the coupling relationship between reservoir diagenetic sequence and the hydrocarbon charging .The po-rosity of blanket sand during the hydrocarbon charging in the lower 2 nd member of the Jurassic Sangonghe Fornation in Block 1 in central Junggar Basin was quantitatively reconstructed by using the compaction trend and inversion back strip -ping methods respectively .The results show that the blanket sand were shallow buried and had good physical properties during the critical hydrocarbon charging period , thus could be good carrrier beds and reservoirs .The blanket sand played a critical role in hydrocarbon transportation and the study area has great exploration potential .
