塔里木盆地HD油田薄砂岩油藏为2层产油层,属于超深、超薄的中低渗层状边水油藏,采用双台阶水平井注水开发。利用相渗曲线,建立该特殊油藏水平井采液(油)指数、吸水指数随含水变化的经验公式,经现场生产及测试资料验证,符合程度较高,对预测该油藏水平井注采能力、合理调整注采关系、提高水驱采收率具有重要指导作用。 The thin sandstone reservoir of the HD Oilfield in the Tarim Basin is a 2-layer oil reservoir. It belongs to the ultra-deep and ultra-thin mid-low permeability layered water reservoir, and is developed by double-stage horizontal well waterflooding. Using the phase-permeability curve, the oil-production (oil) index and water-absorbing index of horizontal wells in this special oil reservoir were established, which were verified by the field production and test data, which were in good agreement with each other. Ability, reasonably adjust the relationship between injection and production, improve waterflood recovery has an important guiding role.
