水平井压裂工艺技术现状及展望

Status and Prospect of Horizontal Well Fracturing Technology

现阶段,延长油田开发中有很大部分都是属于低渗透油气藏,其渗透率低,渗透阻力大,所以,为了提高经济效益,实现油田稳产增产,水平井裂压工艺被广泛应用于各大油田。虽然水平井裂压工艺已经被普遍应用,但在水平井分段裂压施工过程中还存在一定的技术局限性以及设备滞后性,导致目前我国水平井分段裂压技术发展缓慢。基于此,阐述了现阶段我国水平井分段裂压技术现状,以及面临的问题、不足,并对今后水平井裂压工艺的发展趋势进行了分析。

At this stage,a large part of the development of Yanchang Oilfield belongs to low-permeability oil and gas reservoirs, which have low permeability and high permeability resistance.Widely used in major oil fields.Although the fracturing technology of horizontal wells has been widely used,there are still some technical limitations and equipment lags in the staged fracturing construction of horizontal wells,resulting in the slow development of the fracturing technology of horizontal wells in China.Based on this,the current status of the horizontal fracturing technology of horizontal wells in China at this stage,as well as the problems and deficiencies faced,are discussed,and the development trend of the fracturing technology of horizontal wells in the future is analyzed.
