摘　　要：北黄海海域LHIV地区油藏为低孔、低渗砂岩储层,油层易受到钻井液伤害。为保护油气层,优选了适用于该油层的低伤害PEM钻井液体系,室内试验表明PEM钻井液体系具有滤失量低、流变性、热稳定性好、具有一定抗污染能力,抑制性好等特点。PEM钻井液体系成功地应用于LHIV18-3-1井钻进,未出现明显井塌、井漏事故,取得了良好的效果。The North Yellow Sea LHIV block was a low porosity and permeability sandstone reservoir. The drilling fluids damage the reservoir easily. In order to protect the oil formation, the PEM drilling fluid system which suitable for the reservoir has been studied. The experiments showed that the PEM drilling fluid has low filtration loss, good rheological property and temperature stability, anti - pollution ability and inhibition. The PEM drilling fluid used in LHIV18 - 3 - 1 well successful. The hole caving and lost circulation were not occurred and it got good effect.
