摘要
地热流信息是了解地球内部热状态最直接的"窗口",也是开展油气、天然气水合物资源评价的重要基础数据。收集印尼-爪哇地区的地热流数据,结合构造特征、盆地分布等,分析该地区的地热流分布情况以及与油气之间的关系。结果表明:(1)印尼-爪哇地区的地温梯度值大部分处于30~60mk/m,存在部分高异常值;热流值大都处于60~120 m W/m2,存在较多高异常值。(2)印尼-爪哇地区整体处于高热流值区域,这与弧后环境的浅部弧后地幔对流等有关。(3)印尼-爪哇地区的盆地属于地温梯度较高的新生代沉积盆地,这些盆地处于较高的地温场中,有利于烃源岩的油气生成。
Geothermal flow information is the most direct"window"for understanding the thermal state of the earth’s interior,and it is also an important basic data for the evaluation of oil and gas and natural gas hydrate resources.This paper collects heat flow data in Indonesia-Java region,and analyzes the distribution of heat flow in the area and its relationship with oil and gas in combination with structural features and basin distribution.The results show:(1)Most of the geothermal gradients in Indonesia-Java Aera are 30-60 mk/m,with some high abnormal values;the heat flow values are mostly 60-120 mW/m^2,with many high abnormal values.(2)The Indonesia-Java Area is generally in a high heat flow area,which is related to the shallow back-arc mantle convection in the back-arc environment.(3)The basins in the Indonesia-Java Area belong to Cenozoic sedimentary basins with a high geothermal gradient.These basins are located in a high geothermal field,which is conducive to the generation of hydrocarbon source rocks.
