疏松砂岩水力喷砂压裂技术研究

Study on Hydraulic Sand Blasting Fracturing Technology for Unconsolidated Sandstone

以南海某井为例,通过水力喷砂压裂的系统设计,对低渗疏松砂岩油藏进行水力压裂造缝,增大泄油面积,追求产能最大化,验证了疏松砂岩进行水力喷砂压裂的可行性,对提高油井采收率意义重大。

Taking a well in the South China Sea as an example,through the system design of hydraulic sandblasting fracturing,hydraulic fracturing is carried out for low permeability unconsolidated sandstone reservoir to increase the oil drainage area and maximize the production capacity.The feasibility of hydraulic sandblasting fracturing for unconsolidated sandstone is verified,which is of great significance to improve the oil recovery.
