Abstract:

It is generally acknowledged that there are three series of hydrocarbon source rocks in Jurassic,Permian and Carboniferous formations in the east of Junggar Basin.A great quantity of oil whether from the Xiaoquangou Group of Triassic or not is not confirmed in Fukang Sag.However,no agreement has reached whether the Xiaoquangou Group of Triassic in Zhundong exploration area is effective hydrocarbon source rocks.A systematic analysis of the oil generation potential of the hydrocarbons in the area is carried out in this paper.The analysis indicates that the organic matter is rich in abundance and relatively good in the type and that they have come to the peak of oil production at present in thermal evolution.It is suggested that they should be the reasonable source for the hydrocarbon.Previous research discovered that the oil from Well Fu 5 of the Triassic Xiaoquangou Group actually came from the hydrocarbon of Xiaoquangou Group in Fukang Sag,which indicates that the Xiaoquangou in Fukang Sag possesses hydrocarbongenerating potential.Hence,the evaluation of hydrocarbongenerating potential will be of great significance for the oil and gas exploration in the Junggar Basin.
