准噶尔盆地西缘胜利探区岩性油藏勘探技术
|
摘要
2003年以来,准噶尔盆地西缘胜利探区先后实现了浅层稀油、浅层稠油的突破,并高速高效开发了春光油田。科技人员运用石油地质新理论,对前人在准噶尔盆地西缘车排子地区油气勘探取得的成果进行了深入的再研究,总结了该区油气生、运、聚、成藏的规律性认识,通过合情推理明确了勘探方向,取得准噶尔盆地西缘高凸起有望形成大中型油田的认识突破;立足实践、大胆开拓,通过油气源研究明确了车排子地区油源方向及层系;通过油气输导体系的研究证实了两个主要油气输导通道;通过沉积体系的研究为车排子地区储层预测及描述提供了理论依据。坚持在该区进行油气勘探,成功应用了高密度三维地震勘探、类亮点、人工合成地震记录、子波拓频、测井约束反演、多种地震属性分析技术,先后发现稀油、高产油藏14个,浅层气藏6个,浅层稠油油藏3个,已经建成47.5×104t年产原油能力。
Since 2003 breakthroughs have been made successively in the exploration of shallow light oil and shallow heavy oil in Shengli Prospect Area in Western Margin of Junggar Basin, and development of Chunguang Oilfield has been also fulfilled with high speed and high efficiency. With new theories of petroleum geology in the west of the Junggar Basin, researchers further studied the achievements of predecessors in oil and gas exploration in Chepaizi, and summarized regular cognition of oil and gas generation, migration, accumulation and reservoir formation in the area. Through plausible reasoning, the direction of exploration was made clear, and breakthroughs were made in the understanding that large-medium-sized oilfields were expected to form in high lifts in western margin of Junggar Basin. Through the study of oil and gas sources, oil source direction and strata in Chepaizi were made clear. Through the study of oil and gas transporting system, two major oil and gas transporting passages were proved. The study of sedimentary system provides theoretical basis for reservoir prediction and description in the area. Based on persistent oil and gas exploration in the area, techniques of three-dimensional seismic exploration, class highlights, synthetic seismograms, wavelet frequency extension processing, logging constrained inversion, and multiple seismic attribute analysis techniques were applied successfully. Finally 14 light oil reservoirs and high-yield reservoirs, six shallow gas reservoirs, and three shallow heavy oil reservoirs were discovered, with annual production capacity of crude oil reaching 475,000 tons.
