摘要
Abstract
A chlorine-free composite as oil-well cement early strength agent named LL was developed.Combining organic acids A,alcohol amines B and nitrate compound C in a certain ratio,the compressive of cement stone in 6 h as the strength examining index can be designed in optimization test using the orthogonal method.The optimum formula determined by orthogonal was as follows:the weight of organic acids D is 1.0% based on cement,the weight of alcohols amines E is 0.04%, the weight of nitrates F is 4%.Under the optimum proportion,and the performance test of early strength agent LL was carried out after its addition of 2.5% in the cement.The ratio of the thickening time of early strength agent LL slurry to cement slurry is 0.436 less than 0.5,and the compressive strength of cement stone 6 h (39 ℃ and atmospheric pressure)is 11.0 MPa more than 4.0 MPa,they are all meeting the requirement of early strength agent industry standard SY/T5504.4-2008.And it has a good compatibility with the homemade retarders MAM,dispersants FASA and fluid loss AS.关键词
