摘要
准噶尔盆地西缘春风油田石炭系普遍发育火成岩且见到了油气显示,由于地震反射杂乱,油水关系复杂,储层预测难度较大。运用磁力异常、地震多属性和井间裂缝预测等方法对烃源岩的生烃能力和油源贡献进行分析。研究认为,该区石炭系火成岩具备生烃条件,或存在自生自储型油藏。同时,探索了石炭系火成岩水力喷砂压裂、水平井等实用开发技术。以此为指导,成功发现了多个以孔隙-裂缝型储层为主的油藏,并获得了工业油流,证实该区勘探开发潜力较大。
Igneous rocks are developed extensively and oil/gas shows have been observed in Carboniferous reservoirs in Chunfeng Oilfield at the western margin of Junggar Basin. Due to chaotic seismic reflection and complex oil-gas relations,it is difficult to predict reservoir. A multitude of approaches such as magnetic anomaly,seismic multi-attribute and inter-well fissure prediction are applied to analyze the hydrocarbon generation capacity and contribution of source rock. It is believed that the Carboniferous igneous rocks in this area have conditions to generate hydrocarbon or that there are self-generation self-accumulation reservoirs. Moreover,some development technologies such as sand-jet fracturing and horizontal well for Carboniferous igneous rock are studied.With the study results as the guideline,oil pools dominated by pore-fracture reservoirs have been successfully discovered and industrial oil flow has been acquired,which proves the huge potential in this area.
