摘要
侏罗系三工河组二段(J_1s_2)一直是准噶尔盆地中部1区块主力产油层段,目前在产井9口,均为J_1s_2油藏。但其砂体成因多样化且储层特征存在明显差异,导致油藏模式各不相同,多因素复杂性制约了油气勘探进程。根据砂体发育特征将J_1s_2划分为J_1s_2~1、J_1s_2~2,并在此基础上将J_1s_2~1细分为J_1s_2^(11)、J_1s_2^(12)。综合测井、录井、取芯等资料,明确储层非均质特征及其对油水的控制作用。结果表明,中部1区块J_1s_2主要发育泥质岩、细粒砂岩、钙质砂-砾岩三类夹层,控制了J_1s_2~1多期河道叠置而成的厚砂体内油气的运移、聚集,隔夹层垂向和侧向遮挡形成多个独立油藏,控制了油水的分布。
The Jurassic Sangonghe formation second section （ J1 s2 ） has been the main oil production layer in Block Zhong 1 of Junggar basin. The number of production wells is 9, all production wells are J1 s2 reservoir. But its genetic diversity and reservoir characteristics are obviously different, resulting in different reservoir model. Many complex factors restrict the oil and gas exploration process. According to the development characteristics of sand bodies, J1 s2 is divided into J1 s12 and J1 s22 , and J1 s12 is divided into J1 s112 and J1 s122 . Comprehensive logging, coring da-ta, the reservoir heterogeneity and its control effect on oil and water are clear. The results show that J1 s2 of Block Zhong 1 mainly developed three kinds of sandwich that is mudstone, fine sandstone and calcareous sand-conglom-erate, it controls oil and gas in thick sand body that develops in superimposed channel of J1 s12 , interlayer vertical and lateral occlusion form a independent reservoir, control the distribution of oil.
