YZ-1清洁压裂液在甘谷驿油田的应用

Application of YZ-1 Clean Fracturing Fluid in Ganguyi Oilfield

甘谷驿油田地处鄂尔多斯盆地东部,所属区块油藏具有"五低"的特点,即低孔、低渗、低丰度、低温、低压的特点,无自然产能,开发难度大。为了进一步提高甘谷驿油田储层的开发效果,采用了YZ-1清洁压裂液压裂工艺技术,此技术防膨效果和返排率好、残渣含有量较少、且对减少裂缝导流能力损失有利。

Ganguyi oilfield is located in the eastern part of Ordos Basin. The characteristics of the reservoir are low porosity, low permeability, low abundance, low temperature and low pressure; due to no natural production capacity, its development is difficult. In order to further improve development effect of Ganguyi oil reservoir, YZ-1 clean fracturing technology was adopted. The system of the fracturing fluid has high flowback rate, low residue content, excellent anti-swelling effect, and helps to reduce the loss of fracture conductivity.
