摘要

经历多年勘探，顺北地区走滑断裂带陆续取得了油气突破，形成北部油藏、南部凝析气藏、东部过渡到干气藏的油气类型和相态分布格局。因此，从整体油气分布讨论其天然气成因机制、来源和热成熟度，对下一步超深层油气勘探持续推进具有重要参考意义。通过系统采集不同断裂带天然气样品、对顺北地区天然气地球化学特征进行了详细剖析。研究结果表明：除断裂带局部存在较强的热化学硫酸盐还原作用（TSR）改造外，顺北地区天然气总体受TSR改造较小。顺北1号和5号带北段和中段天然气主要为来自干酪根初次裂解的原油伴生气，而5号带南段和4号带天然气主要为早期干酪根裂解气（油伴生气）与晚期原油裂解气的混合。顺北12号带天然气则为深部高温原油裂解气成因，原油裂解级别达到湿气裂解。研究区天然气主要来自下寒武统玉尔吐斯组烃源岩，生气母质具有底栖藻类或者底栖藻类和浮游藻类混源特征。最终，建立了针对玉尔吐斯组烃源岩生烃过程甲烷碳同位素热成熟度回归方程。研究结果可为下一步超深层天然气成因、来源和热成熟度分析提供重要参考。

Abstract

ObjectivePetroleum breakthroughs in the strike-slip fault zones of the northeastern Shunbei area in the last decades reveled the spatial variation in petroleum accumulation types and phase patterns

including the oil accumulation on the north

condensate gas accumulation on the south

and dry gas accumulation on the east. Therefore

to further advance ultra-deep petroleum exploration

it is crucial to reveal the genesis mechanism

source

and thermal maturation of the natural gas from the perspective of overall petroleum distribution. MethodsThis study systematically collected gas samples from various fault zones in the Shunbei area in order to analyze the geochemical characteristics of natural gas and reveal its generation mechanism or thermal evolution process. Results The results indicate that the natural gas in the Shunbei area was minimally affected by TSR even though some parts of the fault zones showed strong modification of thermal-chemical sulfate reduction (TSR). The natural gases in the No. 1 fault zone and in the northern and middle sections of the No. 5 fault zone are primarily crude oil-associated gases generated by primary kerogen cracking. In contrast

the natural gases in the southern section of the No. 5 and No. 4 fault zones were mainly the mixture of early kerogen cracking gas (oil-associated gas) and late crude oil cracking gas. The natural gas in the Shunbei No. 12 fault zone originated from deeper

high-temperature crude oil cracking gas

which occurred at the wet gas stage. The natural gases in the study area predominantly came from the source rocks of the Lower Cambrian Yurtus Formation

and the parent material of these gases is characterized by benthic algae or a mixture of benthic and planktonic algae. Finally

a regression equation for thermal maturity calculation based on the carbon isotope of methane was established for the hydrocarbon generation process in the source rocks of the Yurtus Formation. Conclusion The research findings provide important insights into the origin

source

and thermal maturity of ultra-deep gas

offering valuable references for future studies on hydrocarbon generation in the Shunbei area.
