针对中原油田文88块深层高压低渗油藏储层发育不稳定,采收率低的开发难点,文章以单砂体沉积微相研究为基础,通过沉积相约束下的合理层段组合、注采井距、注采井网的合理配置研究、相控剩余油挖潜研究,并选择适应高压低渗透油藏的配套工艺技术等开发实践,开展深层高压低渗透油藏提高采收率技术研究,探索高压低渗透油藏提高采收率的有效途径。
In view of the difficult development of the reservoirs in Wen-88 block high-pressure and low-permeability reservoirs in Zhongyuan Oilfield and the low recovery rate, based on the study of sedimentary microfacies of single sand body and the reasonable combination of layers under the constraints of sedimentary facies, Well spacing, well allocation of injection and production well patterns, research on potential tapping potential of phased residual oil, and development and application of matching technology to meet the requirements of high pressure and low permeability reservoirs, to carry out researches on enhanced oil recovery of deep high pressure and low permeability reservoirs, Exploring Effective Ways to Improve Oil Recovery in High Pressure and Low Permeability Reservoirs.
