| 摘要: |
| 本文以石炭系为主要研究目的层,综合地层、构造、油气等研究成果,从目的层生烃条件、储集条件及生储盖组合等方面评述了研究区石油地质条件。下石炭统烃源岩为研究区主要烃源岩,分布广、厚度较大,有机质丰度较高、成熟度较高,生烃潜力较大;储层主要发育孔隙型和裂缝型两种类型;盖层主要为石炭系和二叠系。结合生、储、盖条件综合分析,研究区发育4套生、储、盖组合,并根据各构造单元油气的地质条件,将研究区划分为两个远景区:西部坳陷带(特斯布拉克坳陷和科克潘索尔坳陷北部)和东部隆起带(萨雷苏隆起和塔斯金隆起北部),4个最有利局部构造:西背斜、克济尔卡克、塔拉普及中萨雷苏构造。 |

| Abstract: |
| The examination of petroleum geology is based on the hydrocarbon generation,reservoir quality,and source-reservoir-seal associations in the Carboniferous strata as the main target strata in the Zhezkazgan region of the Chu-Sarysu Basin,Kazakhstan.The Lower Carboniferous source rocks with greater thickness are characterized by higher abundance and maturity of organic matter,and thus have great potential of hydrocarbon generation.The reservoir rocks dominantly consist of two types: pore-type and fissure-type.The seal rocks are composed of the Carboniferous and Permian strata.Four source-reservoir-seal associations are recognized in the study area.Two prospects include the western depression and eastern uplift,and four most favourable structures for hydrocarbon accumulation include West Anticline Structure,Kezerkak Structure,Talap Structure and Central Sarysu Structure. |
