摘要:纯化油田薄互层低渗油藏处于中高含水开发阶段,由于层多、层薄、非均质性强,“注不进、采不出”的矛盾突出。径向水射流作为一项低成本技术在纯化油田薄互层低渗透油藏开发调整过程中得到较多应用。基于油水井所在区域的物性、动态、径向水射流等数据,研究了径向水射流在薄互层低渗油藏的适应性及开发效果的影响因素,建立了薄互层低渗油藏径向水射流适应性标准。实践表明:径向水射流和井网井距、层系相适配,改善了水驱开发效果,单井注人能力大幅度改善,但增油效果差异较大;径间水射流油水井存在明显的增产、增注有效期及均衡驱替有效期。

(Research Institute of Exploration and Development of Sinopec Shengli Oifield,Dongying 257015,China) Abstract: The thin-interbedded low-pemeability oil reservoirs in Chunhua Oilfiled are in the development stage with high water cut, because of the multiple and thin layers and strong heterogeneity, the contradictions that the layers cannot be injected and produced are rather serious. As a low-cost technique, the water radial jet has been widely applied in the development adjustment of these reservoirs. Based on the physical properties, dynamic param-eters, radial water jet data and so on in the regions of the oil and water wells, the adaptability for the jet in these kinds of the reservoir and moreover the influencing factors of the development effects were studied, the adaptability criteria of the radial water jet in the thin-interbedded low-permeability oil reservoirs were established. The field practice shows that the development effects of the water flooding can be improved by the adaptation between the ra-dial water jet and well patterns and series of the layer, the injection capacity of the single well has greatly im-proved, but the oil incremental effects have a significant difference; there are rather obvious incremental injection and production periods and furthermore so are the equilibrium displacement validities for the oil and water wells. Key words: Chunhua Oilfiled; thin interbed; low-permeability oil reservoir; water radial jet; heterogeneity
