利用非地震资料综合研究鄂尔多斯盆地姬塬地区油气有利区

Studying the Oil-gas Favorable Zone in Jiyuan Region by Integrated Study of None-seismic Data

在鄂尔多斯盆地姬塬地区,利用非地震勘探方法——重力进行场源分离、界面反演对三叠系界面起伏、局部构造以及与古地貌的关系进行研究,利用遥感资料研究地表裂隙及其分布规律;利用油气化探对有利构造油气微渗漏的分布特征和油气属性进行研究。最后综合这几种资料指出姬塬地区三叠系有利勘探区。

In the Jiyuan region of Ordos basin, non-seismic exploration methods were used. Gravity was used to separate the gravity fields and invert the interface of Triassic to study the flucuation of interface, local structure and the relation between the interface and the palaeogeomorphology. Remote sensing data were used to study the surface fracture and its distribution. Hydrocarbon geochemical method was used to study the micropercolation of oil and the nature of oil, finally the favorable exploration zones of Triassic were given by integrating the three kinds of data.
