分层压裂工艺应用现状

Application Status Quo of Separate-Layer Fracturing Technology

对多层系开发低渗透油田,储层平面、纵向非均质性非常严重,层间差异大,以往笼统压裂后造成的不平衡改造及出砂问题已经严重制约着油田开发效果。为此人们采用了分层压裂工艺,改善了储层动用状况。介绍了选择性分层压裂技术研究现状,为油田压裂施工时选择适合的分层压裂工艺提供参考。

For the low permeability oilfield with many zones, the reservoir plane and longitudinal heterogeneity are severe. Difference among horizons is huge. Imbalance reconstruction and sand production caused by previously gen- eral fracturing has restricted the effects of oilfield development. Therefore, we utilized the separate layer fracturing techniques to improve the producing situation of reservoirs. Status quo of research on selective separate - layer frac- turing technology is introduced, which could provide reference for choosing the suitable separate - layer fracturing technology for the oilfield fracturing.
