| 摘 要： | 低渗透储集层的自然产能很低。若油井以自然产能生产,油井产量的递减速度并不快,而是与中高渗透储集层基本相同。若迫使油井以较高的初期产量投产,油井的产量递减速度必然很快,这是初期开采、后期亏空的必然结果,并不是储集层的应力敏感性所致。

| Abstract: | Natural productivity of low-permeability reservoirs is quite low. If wells produce at natural productivity, their tlow rates decnne with the same speed as the mid- and high-permeability reservoirs. It wells produce at higher rate than their natural productivity, the flow rates will certainly decline with higher speed, which is the inevitable result of earlier exploitation and late voidation of reservoirs. High speed deelinationof flow rates of low-permeability reservoirs are not related to stress sensitivity in reservoir rocks. |
