河南油区魏岗油田构造复杂，油层较薄，平面物性变化大，储集层流动孔隙小，地下油水渗流阻力大，加上原油的“两高一低”（ 高含蜡、高凝固点、低含硫量） 特点，微观水驱油特征表现出驱替阻力进一步加大，宏观水驱油特征上表现出油田注水启动压力高。该油田采取常压注水方式开采，多数单井很难达到配注要求，区块单元难以达到方案设计的开发效果，采用常温注水开发则必须采用整体高压注水。经过高压注水论证、单井试注、区块高压注水推广及全油田高压注水推广，实现了高凝油藏整体高压注水长期高效开发的目标，创出了河南油区水驱油田中开发指标的“四个第一”（ 稳产年限最长、含水上升最慢、地层压力保持水平最高、存水率下降最缓） ，使整体高压注水开发模式在魏岗油田这种中渗透高凝油藏的水驱开发中取得成功。图４ 表１ 参２（杨堃摘）
The Weigang oilfield in Henan Oilfield is characterized by complex structures, thin oil layers, large changes in the physical properties of the reservoirs, small flow pores in the reservoirs and large seepage resistance of the oil and water in the underground areas, plus “two highs and one low” (high wax, high freezing point, low Sulfur content). The micro-water flooding characteristics showed a further increase in displacement resistance. The macroscopic water flooding characteristics showed a high starting pressure of oilfield water injection. The oilfield adopts normal pressure water injection method. Most single wells are difficult to meet the requirements of injection. It is difficult for block units to achieve the development effect of scheme design. For normal temperature water injection development, the overall high pressure water injection must be adopted. After high-pressure water injection demonstration, single well test injection, high-pressure water flooding promotion and high-pressure waterflooding in the whole oilfield, the goal of long-term and high-efficiency high-pressure waterflooding in high-oil reservoirs has been achieved and an indicator for the development of waterflooding oilfields in Henan oilfield The “four firsts” (the longest stable yield, the slowest rise in water cut, the highest level of formation pressure, and the slowest drop in water storage rate) make the overall high-pressure waterflooding development model permeate high-pourover reservoirs in Weigang Oilfield Water flooding development success.
