摘　　要：针对中原油田文 33块沙三上亚段油藏埋藏深、高温、高压、低渗透等地质特点和近 10余年来一直注不进水、难采出、开发基本面临瘫痪状态的实际情况 ,通过开展逐层上返先导试验 ,结合细分层系、加密井网 ,并采取压裂改造、改善水质等技术措施 。The reservoir in the upper part of Sha 3 formation in block Wen 33, Zhongyuan oilfield, was deeply buried, of high temperature and pressure, and low permeable. In more than last 10 years, this reservoir has been unable in injection and difficult in production, and the development was almost in paralysis. Under this situation, many technological measures have been adopted, including pilot test of lifting layer by layer, subdividing strata, infilling pattern, fracturing reconstruct, and improving water quality. As a result, full scale water flooding development has been realized in this deep and low permeability reservoir.
