摘　　要：江家店油田地质构造复杂,内部断层十分发育,预示着其依旧有较大的油气勘探潜力。由于该区发育众多断距较小的低序级断层,且目前对低序级断层的识别和勘探研究程度较低,因此,需要对低序级断层的构造精细解释及其控藏作用进行研究。该区发育北东-南西向、近东西向以及南北向三组低序级断层,在二级、三级断层附近,低序级断层与主干断层以斜交式分布,远离二级、三级断层,低序级断层呈现不同方向分布。利用相干体切片方法能够识别出江家店油田低序级断层,通过对低序级断层的构造精细解释,进而分析该区成藏模式,主要有构造控制的层状油藏和构造-岩性油藏,此外有少量透镜体岩性油藏。低序级断层的精细解释及其控藏作用的研究对油气的勘探开发具有重要意义。Jiangjiadian Oilfield has complex geological structure and well-developed internal faults,which indicates that it still has great oil and gas exploration potential.Due to the development of numerous low-sequence faults with small fault intervals in the area,the identification and exploration are relatively low at present,it is necessary to study the fine-structural interpretation and the reservoir control.The area is characterized by three sets of low-sequence faults:northeast-southwest,nearly east-west,and north-south.Near the second and third level faults,the faults are distributed diagonally with the main faults,far away from the second and third level ones and showing different directions.Therefore,they can be identified by the method of coherent volume slice.Through structural interpretation,the accumulation model of this area is analyzed.There are mainly stratified reservoirs controlled by structure and structure-lithology reservoirs.Besides,there are a few lenticular-lithologic reservoirs.The precise interpretation and reservoir control of low order faults are of great significance for the exploration and development of oil and gas.
