摘要/Abstract

摘要： 德古2井包裹体分析表明，油气进入德古2井圈闭的时间是在沙三段一馆陶组沉积时期，天然气组分分析表明，在烃源岩的低熟和成熟阶段早期，油气就开始运移、聚集于德古2井圈闭，德古2井烃类气体主要来自于班型干酪根的早期裂解气。天然气碳同位素分析表现出低熟的煤成气特征，天然气成熟度Ro约为0.8%。石炭系一二叠系和奥陶系储层差，石炭系一二叠系煤系地层生排烃能力低，是德古2井获低产气流的主要原因。

Abstract:

Well Degu 2 is located in construction of Bixue Dian in Dezhou sag of Linqing expression，Shengli oilfield. Analysis of inclusion show that the time which oil&gas enter into trap of well Degu 2 is at the period of sedimentation in Shashan Member-Guantao Formation. Analysis of gas component show that oil
&gas begin to migration in the period of low mature and mature for source rock, and accumulate to trap of well Degu 2. Gas in hydrocarbon is mainly from the crack gas of early kerogen in Ⅲtype kerogen. The character of coal-genetic gas is low mature based on the analysis of carbon isotope in gas. Maturity of gas is about 0. 8% so on. Reservoir in Carboniferouse-Permian and Ordovician is bad, coal-bearing seam in Carbonniferouse-Permian have a poor capacity of hydrocarbon-generating, poor capacity of hydrocarbon-generating and migration of Carbonifer-ouse-Permian is mainly reason of failure for the exploration well Dey 2.

Key words: well Degu 2, Linqing expression, analysis onreservoir formation
