为了研究“压胀松动”增产技术的增产效果和对套管的影响,在延长石油管理局子长油矿对4242 井进行了现场实验.该技术采用强动载波在地层深处叠加的方法,造成压胀条件,松动岩石,增大近井带渗透率,提高油井产量.施工后,该井产量增加为原来的4 倍多.本次实验工艺上是成功的, 首先是按设计要求引爆了炸药,其二是由于采取了保护措施,使套管变形局限在施工段处,不影响下泵,不影响油井生产;套管强度校核分析也证明了套管不会破坏.施工后地质效果明显.
In order to study the effect of increasing production of “bulking loosening” and its effect on casing, a field experiment was carried out on 4242 well in Yanchang Oilfield Bureau. The technique uses a method of superposition of a strong moving carrier in the depths of a formation to cause the conditions of pressure expansion, loosening the rock, increasing the permeability near the wellbore and increasing the production of the well. After the construction, the well production increased more than 4 times. The experimental process is successful, the first is detonated according to the design requirements of the explosives, and the other is due to take protective measures, the casing deformation is limited to the construction section, does not affect the pump, does not affect the production of wells; casing strength Analysis also proved that the casing will not be damaged. Geological effect after construction is obvious.
