摘要:

Marsel探区位于哈萨克斯坦境内的楚-萨雷苏盆地,面积1.85×104km2,主要发育泥盆系、石炭系、二叠系地层。前苏联时期经35年勘探发现天然气储量137×108m3;加拿大Condor公司开展5年勘探发现天然气储量60×108m3;中科华康石油公司获得探矿权后,委托中国石油大学(北京)和中国地质大学(北京)相关力量进行了为期近3年的研究。应用叠复连续油气藏成因模式,结合对已有资料的重新处理与解释,研究了地层展布特征、构造演化特征、生储盖组合特征和油气运聚特征,预测出探区内存在一个广泛连续分布、面积超过2 500 km2的含气区。通过77口探井的钻探结果分析、相关测井资料中含气层重新解释、地震资料中各目的层含气性特殊处理和追踪、与国内外叠覆连续气藏产状特征比较,检测到Marsel探区内南哈气田的存在并厘定了含气边界、含气范围和含气层有效厚度分布。基于国际PRMS系统评价出南哈气田可采天然气资源储量最佳估值达18 049×108m3,国际评价公司(GCA)审定当前条件下已达到天然气3C级别可采资源储量为5 159×108m3。南哈气田位于中亚腹地的哈萨克斯坦境内,距中国已建成的第3条输气管线不到150 km,其发现将启迪在中亚仍至世界其他地区发现更多类似的非常规叠复连续的油气资源,为建设新丝绸之路经济带作出重要贡献。

Abstract:

The Marsel exploration area is located within the Chu-Sarysu Basin in Kazakhstan. It covers an area of 1.85×104km2 and mainly develops sedimentary formations of the Devonian, Carboniferous, and Permian. Previous exploration by the former Soviet Union took 35 years and discovered gas reserves of 137×108m3. Later, the Canadian Condor Company explored this area for 5 years and discovered gas reserves of 60×108m3. More recently, the Chinese Zhongke Huakang Oil Company obtained the exploration right and authorized research teams from the China University of Petroleum (Beijing) and China University of Geosciences (Beijing) to investigate the Marsel area over a period of 3 years. This study elucidated the characteristics of strata distribution, structure evolution, reservoir-caprock assemblages, and hydrocarbon migration and accumulation in Marsel based on the genetic model of superimposed continuous hydrocarbon reservoirs and combined with re-analysis and interpretation of the existing data. A continuous gas-bearing area larger than 2 500 km2 was predicted in the exploratory area. Additionally, this study analyzed the drilling data from 77 exploration wells, re-interpreted gas-bearing layers using well logging data, specifically processed and tracked the gas-bearing property of target layers with seismic data, and further compared the occurrence of gas layers with superimposed continuous gas reservoirs elsewhere, domestically and overseas. The South Kazakhstan gas field was discovered in the exploration area, and its gas-bearing boundary and range as well as the effective thickness of gas layers were identified. According to the international evaluation system of PRMS, the recoverable reserves of natural gas resources in the new gas field can be as large as 18 049×108m3. An international evolution company, GCA, has approved the 3C recoverable reserves of natural gas resources as 5 159×108m3. This gas field is located in Kazakhstan, the hinterland of Central Asia, less than 150 km away from the third gas pipeline built by China. The discovery of this gas field will promote the exploration and development of similar unconventional superimposed oil and gas resources in Central Asia and other places in the world. It will also play a role in boosting the economy of the new Silk Road.

Key words: Kazakhstan, Chu-Sarysu Basin, Marsel exploration area, superimposed continuous gas field, South Kazakhstan gas field
