| 摘 要： | 由于坪北油田储层物性差,孔隙度低,渗透率低,主要属于小孔细喉道,开采过程中很容易受到伤害,并造成油井近井地层的堵塞,从而使油井在措施后的较短时间内产量下滑。从地层堵塞的原因入手,综合考虑影响地层堵塞的各种因素采用合理的酸化解堵工艺,取得较好的现场应用效果。

| Abstract: | The reservoirs in Pingbei Area of Ansai Oilfield are easily damaged because of poor reservoir physical property,low porosity and low permeability.Therefore,they belong to small pore and fine throat,resulting in stratum plugging of the well pre-bore and production shortfall during the shorter time after oil well stimulation.Beginning with the reasons for stratum plugging,the authors comprehensively ponder over various factors of stratum plugging and utilize reasonable acidization technique for treating plugging,which gains better application effects on the spot. |
