塔里木盆地北方新发现的哈拉哈塘油田，潜在石油资源量达700多亿桶。哈拉哈塘油田原油有机地球化学资料表明，该油田原油为中成熟、生物降解原油，属于同一个油族，来源于同一个古生界海相油源。对同时代含水和含烃包裹体数据的建模分别提供了100°C至110°C和大约39至59 MPa（5656-8557 psi）的流体捕获温度和压力。流体包裹体数据加上以前的盆地模型研究表明，一个单一的延长石油运移事件在二叠纪。原油的Re-Os同位素年龄为285 ± 48 Ma。通过埋藏史模拟，该年龄与古生代源的成熟时间一致，但稍老（1.55 - 5.5百万年）。与盆地模拟结合流体包裹体分析和已发表的储层伊利石K-Ar年龄所揭示的油气运聚成藏时间相比，因此，原油Re-Os年龄表明，塔里木盆地哈拉哈塘坳陷的原油生成时间为早二叠世，而不是志留纪，盆地模拟、流体包裹体分析和伊利石K-Ar年龄记录表明，原油的运移和聚集时间为中晚二叠世。该研究将原油Re-Os同位素定年与传统的分析方法（有机地球化学和流体包裹体分析）相结合，对油气演化进行了研究，不仅对塔里木盆地的油气勘探具有推动作用，而且对世界范围内的油气系统也具有一定的借鉴意义。
The newly discovered Halahatang oil field in the northern Tarim Basin has a potential resource of more than 70 billion bbl of oil. Oil organic geochemical data from the Halahatang oil field indicate that the oils are of moderate maturity, biodegraded, and represent one oil family, derived from the same Paleozoic marine source. Modeling of coeval aqueous and hydrocarbon-bearing inclusion data provide fluid trapping temperatures and pressures of 100°C to 110°C and approximately 39 to 59 MPa (∼5656–8557 psi), respectively. The fluid inclusion data coupled with the previous basin model studies suggest a single prolonged oil migration event during the Permian. The Re–Os isotope data of the oil yields an early Permian Re–Os age of 285 ± 48 Ma. The age agrees with the timing of maturation of the Paleozoic source via burial history modeling but is slightly older (∼5–55 m.y.) than the oil migration and accumulation timing implied by the basin modeling coupled with fluid inclusion analysis and the published reservoir illite K–Ar dates. Thus, the oil Re–Os date suggests that oil generation in the Halahatang depression of the Tarim Basin occurred during the early Permian rather than the Silurian as previously proposed, with subsequent oil migration and accumulation occurring during the middle–late Permian as recorded by basin modeling, coupled with fluid inclusion analysis and illite K–Ar dating. In addition to promoting petroleum exploration in the Tarim Basin, this study, which combines crude oil Re–Os isotope dating and traditional analytical methods (organic geochemistry and fluid inclusion analysis) to constrain petroleum evolution, is applicable to hydrocarbon systems worldwide.
