摘　　要：常规油气资源的开发已进入中后期,低渗、超低渗油气田的有效开发成为油田增产稳产的关键。利用水平井水力压裂技术对低渗、超低渗储层进行改造,改变了储层流体的流动状态,扩大了泄油半径,使其中的油气资源得到了更有效开发。由于地层情况复杂,针对不同的地质条件、储层特征,应选择合适的压裂方式,以便获得更好的储层改造效果。The development of conventional oil and gas resources has entered into the middle and late period. The effective development of low permeability and ultra low permeability oil and gas fields has become the key to yield increase and stable yield. The hydraulic fracturing technique of horizontal well is always used to transform the low permeability and ultra low permeability reservoirs, which changes the flow state of the reservoir fluid and enlarges the drain radius, so that the oil and gas resources can be developed more effectively. Due to the complicated stratigraphic conditions, suitable fracturing methods should be selected for different geological conditions and reservoir characteristics in order to obtain better reservoir modification effect.
