摘要:

塔里木盆地西南坳陷叶城凹陷以二叠系为主力烃源岩,前人多按单一的海相或湖相烃源岩笼统分析,未考虑二叠系烃源岩不同组段及其沉积环境和沉积相带的差异。本文通过对叶城凹陷二叠系开展野外地质调查,结合该区钻井资料,首次将烃源岩分析精细到组,结果显示,叶城小区和和田小区二叠系分别以棋盘组和普司格组上段为主力烃源岩,但两者在分布和地化指标上有较大差异。其中棋盘组以浅海陆棚相为主,分布于凹陷西部的和什拉甫-莫莫克地区,烃源岩平均厚度大于100 m,总有机碳质量分数平均1.06%,类型为Ⅱ型,处于高-过成熟阶段。普司格组上段以湖相为主,分布于凹陷东部的普萨-杜瓦地区,烃源岩平均厚度大于200 m,总有机碳质量分数平均0.97%,类型为Ⅱ型和Ⅲ型之间,处于生油高峰阶段。二叠系这两套烃源岩具有较好的生烃能力,相比之下普司格组上段湖相烃源岩生烃潜力明显好于棋盘组浅海陆棚相。通过正构烷烃碳同位素比值和生物标志化合物分析,普司格组上段烃源岩为柯东1井原油的油源。结合储盖条件综合分析,叶城凹陷以甫沙-克里阳地区为油气勘探最有利区。

Abstract:

Permian is the main period for the accumulation of the hydrocarbon source rocks in the Yecheng depression of southwestern Tarim basin. Previous works hitherto have commonly treated simply the Permian oil-shales as a marine or lacustrine hydrocarbon source rocks, which have ignored an important fact that different formations of the Permian formed in different sedimentary environments, and show different sedimentary facies and have different oil and gas potentials. Based on the geological survey in Yecheng depression, combined with the drilling data, our results indicate that the key source units include Qipan and Pusige Formations. They are the main Permian source rocks in Yecheng (in the northwest) and Hetian (in the southeast) areas of the Yecheng depression. According to facies analysis and organic geochemical results, we interpreted that the Qipan Formation was deposited in a shallow marine shelf environment and distributed in Heshilafu-Momoke area of the northwestern Yecheng depression. The average thickness of source rock is more than 100 meters, the type Ⅱ organic matter have reached a high maturity evolution stage. In contrast, Pusige Formation was deposited in a lacustrine facies sedimentary environment and distributed in Pusha-Duwa area, the average thickness of source rock is more than 200 meters. It shows an average TOC content of 0.97% and type Ⅱ or Ⅲ organic matter which has reached the peak stage of hydrocarbon generation. Concerning the hydrocarbon potential of the two formations, Upper Pusige Formation is better than Qipan Formation. In order to trace the oil-source of a nearby commercial well KD1, we correlate the data sets of radiometric carbon isotope ratios and biomarkers of normal alkanes between the oil and different source rocks. Our results show that the oil trapped in the well KD1 comes from the Upper Pusige Formation source rocks. Combined with the comprehensive analysis of the petroleum system, we indicated that the most favorable exploration target in the region is the area of Fusha-Keliyang in the eastern Yecheng depression.

Key words: Tarim basin, Yecheng depression, Permian, shallow marine and lacustrine source rocks, Pusige Formation, Qipan Formation
