解堵工艺在七里村油田的研究和应用

Research and Application of Broken Down Technology in Qili Village Oilfield

七里村油田的储层物性(孔隙度、渗透率)比较差,生产过程中每口井几乎都要进行多次压裂,加上修井等其他因素的影响,导致近井筒地带的储层不可避免的被堵塞,使油井产量大幅下降。为了消除这种堵塞的不良影响,提高油井产量,七里村油田开展了许多解堵工艺技术的研究和应用工作,取得了一定的成效和认识。

Physical property （porosity, permeability ） of the reservoir in Qili village oilfield is bad. Nearly each well has been fractured many times in production. Effected by other factors like workover, the reservoir near borehole zone is blocked unavoidably, it leads to well production dramatically decline. In order to eliminate the influence of the block and increase the well production, carried out in Qih village oilfield, and take a good research and application of many broken down technologies are effect.
