高导流压裂技术在新疆油田准东采油厂的应用

Application of high conductivity fracturing technology in Zhundong Oil Production Plant of Xinjiang Oilfield

针对低渗透油气藏的特点,对于低渗透储层改造的关键点在于提高其导流能力,高导流通道压裂技术通过高导流聚合剂与支撑剂同步拌注,采用脉冲加砂的方式,使支撑团簇离散分布在裂缝中,支撑剂团簇之间的大通道成为油气运移的主要通道,极大改善储层导流能力。在新疆油田准东采油厂进行了3口井共5级压裂施工试验,验证了高导流通道技术在增产、提质方面优越性,具有广泛的应用空间。

According to the characteristics of low permeability oil and gas reservoirs,the key point of the reconstruction of low permeability reservoir is to improve its conductivity.Through the high conductivity channel fracturing,the polymer and proppant are mixed synchronously,and the pulse sand is adopted to make the support clusters dispersed in the fractures.The large channel between the proppant clusters becomes the main channel for oil and gas migration,which greatly improves the permeability of the reservoir.A total of 5 stages fracturing tests were carried out on 3 Wells in Zhundong Oil Production Plant of Xinjiang Oilfield,which verified the advantages of high diversion channel technology in terms of production increase and quality improvement,and it has a wide range of application space.
