藏1井是伦坡拉盆地首次获得工业油气突破的钻井,原油的地球化学特征研究表明原油主要是常规的高腊低硫的原油,化学类型为芳香中间型,原油的母质类型主要是腐泥─腐殖腐泥型,藻类和高等植物是成油的原始母质,源岩的沉积环境为咸水湖盆;原油的成熟演化阶段基本处于低熟─成熟阶段;原油的后生变化主要是水洗和氧化,而生物降解作用相对微弱。
Well Cang-1 is the first breakthrough in industrial exploration in Lunpola Basin. The study on the geochemical characteristics of crude oil shows that the crude oil is mainly conventional high sulfur and low sulfur crude oil, the chemical type is aromatic middle type, and the parent type of crude oil is mainly sapropel ─ Humus sapropelic, algae and higher plants are the original parent material forming oil, the sedimentary environment of source rocks is saltwater lake basin; the mature evolution stage of crude oil is in the low-maturity-mature stage basically; The epiphytic changes of crude oil are mainly washed and oxidized, The biodegradation is relatively weak.
