摘　　要：对鸡西盆地城子河组、穆棱组岩石薄片进行显微镜下观察,挑选包裹体发育的样品切制包裹体薄片,在冷热台上开展流体包裹体均一温度测试,结合鸡西盆地的埋藏史和热史,探讨研究区城子河组、穆棱组的油气运移期次以及成藏时间。研究结果表明,研究区发生过两期四个幕次的油气运移事件,可划分为80~77 Ma和45~38 Ma两个期次,其中,城子河组有过三幕油气运移,充注时间分别为80 Ma、45 Ma及38 Ma,穆棱组在77 Ma发生过一幕油气充注。本次研究结果与鸡西盆地经历的两次构造运动相吻合:即(1)库拉板块(活动期120~65 Ma)对中国大陆边缘作用影响;(2)始新世—渐新世,约40 Ma的喜山早期运动,每次构造运动都伴随着油气运聚事件。The rock slides of Chengzihe and Muling formations in Jixi Basin were studied under the microscope, and samples with a great number of fluid inclusions were chosen to make inclusion slides. The homogenization temperature test of fluid inclusion was subsequently performed on the freezing and heating stage.By analyzing the testing temperature data in combination with the burial history and thermal history of Jixi Basin, the oil and gas migration periods and accumulation stages of Chengzihe and Muling formations in Jixi Basin were discussed.The results showed that two stages and four episodes of hydrocarbon migration and accumulation occurred in the study area, which could be divided into two periods of 80-77 Ma and 45-38 Ma.There were three episodes of oil and gas migration in Chengzihe Formation,the filling time was 80 Ma, 45 Ma and 38 Ma, respectively, and there was one episode of oil and gas filling in Muling Formation in 77 Ma.The results of this study are consistent with two tectonic movements in the Jixi Basin：①Kula plate activity, in a period of 120-65 Ma, which had shaped China＇s mainland margin;②the earlier Himalayan movement in about 40 Ma in Eocene and Oligocene, both of which were accompanied by the migration and accumulation of oil and gas.
