摘要

钻井和储层穿透效率的提高直接关系到所用钻井泥浆的质量。正确选择泥浆类型及其成分将保持地层产能、井壁稳定性,并减少其他复杂情况发生的可能性。在压力增加的情况下,油气运营商使用重晶石、菱铁矿或赤铁矿加重剂作为钻井泥浆成分中的加重成分。但是,使用这些添加剂穿透生产性地层会导致储层的过滤特性降低,因为几乎不可能将它们从孔隙通道中去除。因此,提出了以甲酸盐为基础,添加碳酸盐加重剂作为酸溶性桥接剂的无重晶石增密钻井泥浆。给出了无重晶石溶液流变参数的实验研究结果,并对所得数据进行了分析。根据对比结果,建议采用以甲酸盐(甲酸钠和甲酸钾)为基础,加入分子质量为2700万的部分水解聚丙烯酰胺的高密度钻井泥浆。

Study on the rheological properties of barite-free drilling mud with high density
Improved drilling and reservoir penetration efficiency is directly related to the quality of the drilling mud used. The right choice of mud type and its components will preserve formation productivity, stability of the well walls and reduce the probability of other complications. Oil and gas operators use barite, less often siderite or hematite weighting agent as a weighting component in the composition of drilling muds for the conditions of increased pressure. But the use of these additives for the penetration of the productive formation leads to the reduction of filtration characteristics of the reservoir, as it is almost impossible to remove them from the pore channels. Therefore, barite-free drilling mud of increased density based on formic acid salts with the addition of carbonate weighting agent as an acid-soluble bridging agent is proposed. The results of experimental investigations on rheological parameters of barite-free solutions are given and the obtained data are analyzed. Based on the comparison of results it is recommended to use high-density drilling mud on the basis of formic acid salts (sodium and potassium formate) and with the addition of partially hydrolyzed polyacrylamide with molecular mass of 27 million.
