水平井分段压裂技术研究

Technology Study of Staged Fracturing of Horizontal Wells

目前,我国开发较早的大型油田已进入开发后期,出油量下降,含水量大幅上升,开采难度增大。为了适应经济的发展,大力开采低渗透油气藏成为增加产量的主要手段。而水平井分段压裂增产措施是开采低渗透油气藏的最佳方法,对提高单井产量有重要作用。

Nowadays, large -scale oil fields tapped early in China have been in the late stage of reduction of oil pump capacity and significant increase of water content, making the exploitation development with more difficult. In order to adapt to the economic development, it is the primary means to increase yield by endeavor exploitation of low permeability reservoirs. While the best way to exploit low permeability reservoirs is staged fracture of horizontal wells, which plays an important role in the increase of per - well production.
