摘要
对甲酸钠在钻井液体系中的应用进行了研究。对甲酸钠钻井液进行了耐温试验、储层保护试验及盐敏试验,结果表明,其钻井液体系具有耐温性好,储层伤害低,但甲酸钠加量过高会导致岩心盐敏伤害,甲酸钠最佳加量为20%,现场使用甲酸钠加重需控制其加量。
The application of cling test, reservoir protection test According to the results of tests, harm to reservoir. However, too core, and the optimum volume of sodium formate in drilling fluid system was studied. Temperature withstan- and salt sensitivity test were conducted for the sodium formate drilling fluid. this drilling fluid is good in temperature withstanding performance with low high addition volume of sodium formate may cause salt sensitivity harm to sodium formate is 20%.
