摘　　要：根据外围“三低”油田的储层特性 ,确立了一种保护低压、低渗储层的新型钻井液———甲酸盐钻井液体系。通过与K2 SO4钻井液性能对比表明 ,两种盐水体系都是保护低压、低渗储层较为理想的钻井液体系。在州 1 3和海拉尔区块的试验应用中 ,表现出了极强的抑制性和保护储层特性。According to the reservoir property of the peripheral “three low”oil fields, a new type of drilling fluid formate drilling fluid system is determined to protect the reservoirs with low pressure and low permeability Compared with the performance of K 2SO 4 drilling fluid, both of them are suitable drilling fluid system to protect low pressure and low permeable reservoirs Their application in Block Zhou 13 and Block Hailaer shows a strong suppression and protection ability with a nice effect of test
