中文摘要	商河油田商三区沙二下亚段储层属低孔低渗储层,其岩性以粉砂、细砂为主,砂泥岩薄互层.储层砂体层间差异小,但层内非均质性很强.经过多年的注水开发,研究区在注采井距、油水井套损、注入水水质等方面的问题日益突出.根据油田的开发现状,针对存在的问题,建议修好并开启所有注水井和生产井,提高注入水的水质,对研究区沙二下采用脉冲式周期注水开发方式开采.
英文摘要	The reservoirs in the lower member of Es2 in Shangsan Region of Shanghe Oilfield are res-ervoirs with low pore and low permeability, where siltstones and fine sands are dominated in its li-thology, sandstones and mudstones are thin arid interbedding. The difference between each sand-body in small intralayer heterogeneity is strong. For many years of waterflooding, the problems on injector-producer spacing, casing failure in oil-water wells and the quality of injection water have be-come more and more serious in the studied area . Based on the present status of oilfield development , aiming at the existed problems, it is proposed that all injectors and producers are repaired and opened, the quality of injection water is improved, the mode of pulse type cyclic water injection is used in the lower member of ES2 in the studied area.
