摘　　要：八面河油田面十四区沙四段储层为泥质胶结疏松砂岩油藏,粉细沙、微粒、粘土分散运移易造成地层堵塞,损害油层渗透性,具有潜在伤害油层的内因。在对油藏潜在伤害因素分析评价的基础上,优选入井液中多种油层保护添加剂,对油井增产措施作业提出了相应的油层保护措施。Reservoirs located in the fourth member of Shahejie formation in Mian 14 district of Ba Mianhe Oil Field are typical unconsolidated sandstone deposits formed by muddy cementation. The scattering and migration of silty fine sands, motes and clay can cause formation plugging and undermine the permeability which poses a threat to the reservoirs. Based on the analysis of the potential threats, this paper suggested adopting the working fluid containing multiple additives that protect the oil stratum during the oil production facilitating process.
