| 摘 要： | 大路沟地区长4＋5层为主要含油层系。此区长4＋5层成藏的控制因素主要有砂体分布受沉积相展布决定,进而对油藏分布起到决定作用,分流河道砂体富集有大量油气;目标区处于凹陷中心、有充足的油源;高渗储层具有较高的电阻率,此类油层为优质储层,具有非常高的试油产量,并且也受成岩作用的影响。

| Abstract: | Chang 4 +5 reservoir in Dalugou area is main oil-bearing series,its controlling factor is sand distribution determined by sedimentary facies,which play a decisive role in distribution of reservoirs.Diversion channel sand accumulation has large oil and gas;the target area in the depression center has sufficient oil source;high permeability reservoirs have high resistivity,it is high-quality oil reservoir,its producing test productivity is very high,and it is also affected by diagenesis. |
