摘要:
塘沽油田古近系沙河街组沙三段发育厚层泥质白云岩与白云质泥岩纹层状特殊岩性体致密油油藏。通过岩心观察、X射线衍射鉴定、扫描电镜分析等技术,系统剖析了特殊岩性体储集空间类型、成因及储层含油性; 利用测井、地震信息有效结合,对特殊岩性体展布范围进行有效识别与精细刻画。在此基础上,优选先导试验区块,进行直井加大斜度井井网部署,利用大规模水力压裂、微地震监测、大斜度井分段压裂等储层改造技术,结合井网调整和循环注气技术探索,塘沽地区致密油在先导试验区块试油获近百吨高产,试采生产稳定,为渤海湾地区致密油规模增储及有效动用奠定了基础。
Abstract:
The tight-oil reservoir in the third member of Palaeogene Shahejie Formation of Tanggu Oilfield was a laminar special lithologic body which was interactively formed by argillaceous dolomite and dolomitic mudstone with thickness.By the means of core observation,X-ray diffraction identification,and scanning electron microscopy(SEM)analysis,etc.,it was systematically analyzed the space type,genesis,and oil-bearing property of the special lithology reservoir.In the powerful combination of well logging and seismic information,the range of the distribution of special lithology body can be effectively identified and described in detail.On this basis,screening the pilot test area,implementing the well pattern deployment of straight and high inclination wells,using reservoir reconstruction technologies including large-scale hydraulic fracturing,microseismic monitoring,high-gradient well fracturing,etc.,combined with well pattern adjustment and cycle gas injection,a high yield of nearly 100 t was obtained in the pilot test of Tanggu Oilfiled and the production testing was stable.This can lay a foundation for increasing tight-oil reserves and the effictive development in Bohai Bay area.
