摘要(Abstract)：

松辽盆地北部中浅层具有形成大规模、连续型致密油藏的有利地质条件,青山口组烃源岩内部和下部分别发育高台子和扶余2套致密油层,具有很大的资源潜力,但应用常规技术难以有效开发动用。大庆油田按照"预探先行、储备技术、评价跟进"思路积极探索致密油藏勘探开发模式,在建立扶余、高台子油层致密油资源精细分类评价,以及"甜点"识别方法的基础上,秉承"水平井+大规模体积压裂"理念,形成了"三优二精一配套"的水平井设计、钻探跟踪及增产改造技术。在致密油水平井段钻探长度、油层钻遇率、压裂方式、压裂段数、压裂规模等方面取得了突破性进展,水平井提产效果显著。针对扶余和高台子油层特定的致密储层地质条件,优选有利区块,通过个性化井网设计和尝试工厂化作业模式,初步建立了3个水平井开发试验区,为松辽盆地北部致密油全面有效开发积累了经验。
The middle-shallow formations in North Songliao Basin have favorable geological conditions to form large-size continuous tight oil reservoirs,and 2 sets of Gaotaizi and Fuyu tight oil formations in and beneath Qingshankou source rocks have a certain tight oil resource potentials.For this part of the resources,the conventional techniques cannot effectively develop them.According to the thoughts of " pre-exploration first and reserving techniques,evaluation second" and then seeking for the effective developing models for Daqing Oilfield,on the bases of the fine classification and evaluation of the above resources and " sweet point" optimizing method,and moreover taking the philosophy of "horizontal well + large-size bulk fracturing",the techniques of "three optimizations,two accuracies & one match" considering horizontal well design,drilling trace and stimulation are generally established.The breakthrough achievements and progress have made in the aspects of the horizontal well length,ratios of the drilled and penetrated tight oil layers,fracturing modes,fracturing segments and fracturing scales and so on.And moreover the tight oil production of the horizontal wells increases obviously.In the light of the specific geological conditions of the tight reservoirs in above two fomiations,the favorable blocks are optimized,and moreover through individualized well pattern design and attempt to industrialized operation pattern,3 horizontal well experimental blocks have been set up,thus the experiences have gained and accumulated for the tight oil exploration and effective development in North Songliao Basin.
