摘要
在钻井过程中,钻井液中的固相和液相沿裂缝侵入储层,造成储层渗透率损害。介绍了裂缝性油藏屏蔽暂堵方法,并对该方法的可行性和重复性进行了评价。结果表明,该屏蔽暂堵方法对裂缝宽度为1mm的油藏是切实可行的,试验数据重复性好。对其它裂缝宽度油藏的屏蔽暂堵方法还需要进一步研究。
Solids and liquids in drilling fluid could cause serious formation damage sometimes. A shield temporary plugging method designed for fractured reservoir is presented, with its feasibility and accuracy evaluated. Tests indicate that this method is practical for plugging reservoir with 1 mm wide fractures.
