准噶尔盆地中部1、3区块走滑断裂特征及石油地质意义
|
摘要
在地质综合分析的基础上,利用二维、三维地震资料分析后认为,准噶尔盆地中部地区1、3区块发育走滑断裂体系。走滑断裂体系在剖面上呈花状构造,平面上具有雁列式、平行式排列特征。走滑断裂体系使研究区具有形成优质油藏的良好输导条件,因此,明确走滑断裂体系在研究区的分布及发育特征,对于加快非构造油气藏勘探、重新认识中部油气勘探潜力具有重要意义。
The geological analysis and 2D and 3D seismic data indicate that the strike-slip faults occur in No.1 and No.3 blocks in central Junggar basin.The characteristic of strike-slip fault system appears flower structure in profile and en-echelon and parallel structure on the plane,which could create good transport conditions for forming high quality reservoirs in this area.It is of an important significance to recognize the distribution and development characteristics of such faults in the studied area for speeding up non-structural or subtle petroleum reservoir exploration and re-understanding of the potentials for prospecting of central Junggar basin.
