doi:10.7657/XJPG20230303

Abstract

Abstract:

22 oil and gas layers in the tight sandstones below the Xishanyao formation were interpreted in the risky exploration Well Qintan-1 in the Shengbei subsag, Turpan-Hami basin. It is necessary to evaluate the encountered source rocks and determine the tight oil source. The source rocks in the Xishanyao formation are non-or poor source rocks in most intervals near Well Taican-2, except the 4 700-4 900 m interval, and are moderate-good source rocks in Well Qintan-1 in the subsag. The source rocks in the Sangonghe formation are moderate to good. The organic matters in the Middle-Lower Jurassic are generally Type Ⅱ₂-Ⅲ. The Xishanyao formation source rocks are mature, while the Sangonghe formation and Badaowan formation source rocks are highly mature. The carbon number of the paraffins in the soluble organic matters in source rocks distributes in a wide range, and the C₂₇-C₂₈-C₂₉ αααR sterane shows a reverse “L” configuration, indicating a hybrid organic matters mainly sourced from terrestrial higher plants. The organic matter of Xishanyao formation has a low gammacerane content and a relatively high pristane-phytane ratio (Pr/Ph), corresponding to a weak oxidation-weak reduction sedimentary environment with relatively low salinity. The organic matter of Sangonghe formation and Badaowan formation have low Pr/Ph and high gammacerane content, showing a strong reduction sedimentary environment with high salinity. β-carotane is developed in the entire Sangonghe formation, and is quite abundant in some intervals, with the content equivalent to that of the main peak n-alkanes, indicating the contribution of halophilic bacteria and a reducing water environment in these intervals. According to the parameters such as C₂₇/C₂₉ αααR sterane, Pr/Ph, C₁₉₊₂₀/C₂₃₊₂₄ tricyclic terpane, C₂₄ tetracyclic terpane/C₂₆ tricyclic terpane, rearranged hopane and β-carotane, it can be inferred that the crude oil in the Sangonghe formation came from the source rocks of the same formation; the crude oil at the bottom of the Xishanyao formation originated from the Sangonghe formation source rocks enriched in β-carotane and underwent secondary migration, and the oil sand extracts from the upper and middle members of the Xishanyao formation are related to the source rocks in the Xishanyao formation.

Key words: Turpan-Hami basin, Shengbei subsag, Middle-Lower Jurassic, tight oil, biomarker, β-carotane, source rock evaluation, oil-source correlation
