Development of Seawater Base Annular Space Protection Fluid Used in Bohai Oilfield

摘要: 随着渤海油田采出液含水逐年升高,油气井和注水井油管、套管腐蚀损坏问题日益严重,并且从降低成本考虑,有必要开发一种水基环空保护液。根据海上平台淡水缺乏的特点,在分析渤海水质情况的基础上,优选出了效果较好的杀菌剂YHZWJ-15和防垢剂BHF-701A,研究出了抗高矿化度盐水的缓蚀剂BHH-509,通过几种单剂复配之后的稳定性实验,开发出一种适用于渤海油田的以海水为基液的环空保护液,其基础配方为海水+0.5%YHZWJ-15+0.01%BHF-701A+0.01%硫脲+0.5%BHH-509。通过挂片实验,该海水基环空保护液对管柱的腐蚀速率可降到0.0051 mm/a。Abstract: A seawater base annular space protection fluid, CP-02.was developed for use in offshore drilling in Bohai oilfield where fresh water is in shortage on platforms.The formulation of CP-02 includes some additives selected through laboratory experiments, such as the biocide YHZWJ-15, scale inhibitor BHF-701 A, and corrosion inhibitor BHH-509, which is suitable for use in seawater.One example of the formulation is as this:Seawater+0.5% YHZWJ-15+0.01% BHF-701A+0.01% thiocarbamide+0.5% BHH-509.The rate of corrosion of the CP-02 to oil well pipes is as low as 0.005, 1 mm/a, indicating its good performance in protecting oil well pipe strings.
