摘要(Abstract)：

松辽盆地北部富油凹陷资源丰富,勘探成熟度高,剩余资源潜力主要为斜坡带、向斜区的低渗小砂体隐蔽性油藏,规模不确定。通过齐家—古龙地区杏西—哈尔温富油区勘探开发一体化实践,提出了斜坡带、向斜区萨尔图、葡萄花油层隐蔽油藏受微构造、低幅度断背斜、断层—岩性多种圈闭控制,沿斜坡带、向斜区串珠状分布的新认识;创新了微构造精准解释、小砂体精细预测与刻画、隐蔽油藏风险评价和按砂布井开发优化设计4项关键技术;建立了萨尔图、葡萄花油层隐蔽油藏"全藏规模建产、分步动用建产和单井建产"3种建产模式。结果表明,勘探开发一体化部署取得了评价井高产比例高、开发井建产节奏快的好效果。研究成果对于松辽盆地及其类似成熟探区效益评价、优化建产,具有一定的指导意义。
The resources of the oil-rich sags in North Songliao Basin are abundant,but the exploration maturity is rather higher,potentiality of surplus resources are mainly the subtle reservoirs with small low-permeability sandbodies and uncertain scales. With the help of the integrated exploration and development practice for Xingxi-Haerwen oil-rich area in Qijia-Gulong oil-rich sag,the new understandings were obtained and presented: the subtle oil reservoirs in Saertu and Putaohua reservoirs of the slope belt and syncline block were controlled by the multiple traps such as the micro-structures,low-amplitude fault anticlines and fault-lithology,and moreover beadedly distributed along the slope belt and the syncline; the following four key techniques were initiated and developed: fine and accurate interpretation of the micro-structures,fine prediction and characterization of the small sandbodies,risk assessment of the subtle oil reservoirs and the optimized design of the well arrangement according to the sandbodies;three types of the producing modes were established for the hidden reservoirs in Saertu and Putaohua reservoirs:producing for the whole reservoirs,producing and developing step-by-step and producing for the individual well.The achievements show that much better effects have been obtained for the integrated exploration and the development i. e. pretty higher high-production ratio for the evaluating wells and greatly faster pace of the production of the developing wells. The research achievements possess a certain guiding significances for the benefit evaluation and optimized production of Songliao Basin and the other similar matured exploring regions.
