| Bai Ma Yao Xian Gaotai—Luo Pang Yuan area located in Zhang Yaoxian Township,on the West of the main oil area Road. It is a typical low permeability reservoir, in which tblock development work has been in full swing. However, with the development and moreunderstanding of the reservoir characteristics, including the oil water movement law moreand more clearly, many development problems and contradictions have been exposed. Inorder to realize the development goal of the region, to enhance the oil reserves extent, andto release the contradiction that appears in the production process, it is very necessary tostudy the geological, structure and petrology characteristics of the reservoircomprehensively. On the basis of the former research, the analysis of reservoir engineeringstudy should be continued to carry out. Combined with reservoir dynamic method, choosepreferably water injection development plan, and confirm the basic geology and reservoirinternal features. The fine geological model is established, and the reservoir developmentscheme is adjusted through the reservoir numerical simulation.And ultimately determine the well pattern is inverted nine spot well pattern, and thewell spacing is480m (injection well to the corner wells)×130m (spacing)---500m×130m.The reasonable flow pressure of production well is8MPa; the reasonable productionpressure difference is9.6-13.3MPa; the maximum injection pressure of water injection is25.8MPa; the productivity of single well is2.2t/d; reasonable oil recovery rate is1.08%; itis advised to take the advanced water injection development, and advanced injection time is80-100days, injection flow rate is18m3/d. |
