对低渗透油层特别强调油层保护并不是因为这类油层比高渗透油层更易受污染,而是因为低渗透油层自然渗透能力差,任何轻微的污染伤害都会导致产能的大幅度降低,因此,低渗透油层的油层保护尤为重要。
Laying particular emphasis on reservoirs in low-permeability reservoirs is not because these reservoirs are more susceptible to contamination than high-permeability reservoirs but because of the low natural permeability of low-permeability reservoirs and any minor pollution damage resulting in a substantial reduction in capacity. Therefore, low-permeability Reservoir protection is particularly important.
