Abstract

In the central part of southern margin of Junggar Basin

Well Hutan1 at the Huxi anticline and Well Tianwan1 at the Dongwan anticline have obtained high-yield oil-gas flows from the Lower Cretaceous to Upper Jurassic reservoirs at a burial depth from 7 300 m to 8 100 m

which has made a major breakthrough in ultra-deep oil-gas exploration

showing a good prospect for hydrocarbon exploration in the ultra-deep lower assemblage of the thrust belt in the southern margin of Junggar Basin. The source and genesis of oil and gas in reservoirs are vital for understanding the hydrocarbon accumulation regularity and controlling factors as well as hydrocarbon resource potential in the ultra-deep lower assemblage. Based on the fine analysis and study of physicochemical and geochemical characteristics of ultra-deep condensate oil at the Huxi anticline and Dongwan anticline

the source and genesis of condensate oil was explored. The results show that the condensate oils in Well Hutan1 and Well Tianwan1 are characterized by low densities

low viscosities

low wax contents and freezing points

and high contents of alkanes

naphthenes and aromatics with low carbon numbers

as well as rich contents of n-alkanes with middle-high carbon numbers

and thus they are classified as light oils with low densities

low wax contents and low freezing points. The condensate oils have a light carbon isotope composition

the δ

C value of whole oil is from -30.7 ‰ to -28.6 ‰

and nC

-nC

n-alkanes have light carbon isotope compositions

especially nC

-nC

n-alkanes

and the corresponding δ

C value is from -29 ‰ to -33 ‰ . The condensate oils have a relatively high abundance of isoprenoids which show equalizing pristine (Pr)and phytane (Ph)contents or having a dominant Ph content

with Pr/Ph ratio from 0.69 to 1.27. In the compositions of biomarkers

and C

steranes and diasteranes are abundant

methylsteranes are

relatively abundant

and C

ααα-20R steranes show a V-shaped distribution. The 20S/(20S+20R)ratio and ββ/(αα＋ββ)ratio of C

sterane are greater than 0.45 and 0.60

respectively. The condensate oils have abundant tricyclic terpenes showed a near-normal distribution with C

terpane as the highest

have very abundant 18α(H)- trisnorneohopane (Ts)

diahopane and C

diahopane

and have a high content of gammacerane with an isomers

indicating that the condensate oil is generated by organic matters deposited in semi-saline to saline lacustrine clay-rich environment. As a whole

the condensate oils from Well Hutan1 and Well Titanwan1 in the ultra-deep reservoir of the central part of southern margin of Junggar Basin have very similar geochemical characteristics with the crude oil/condensate oil from the middle to shallow reservoirs at the Horgos anticline. The condensate oils are derived from the lacustrine source rocks of the Lower Cretaceous Qingshuihe Formation

and are formed by later gas invasion/washing in the early oil reservoirs.
