摘要

摘要: 针对高密度钻井液对润滑性能的要求,采用多元醇、含双键的长链脂肪酸、矿物原料等为原料合成一种高密度钻井液用润滑剂SMJH-1,其为一种接入具有极压抗摩能力化学元素的大分子酯。性能评价结果表明,润滑剂SMJH-1加量为1%、2%和3%时,润滑系数降低率为24.2%、33.6%、38.3%,具有良好的润滑性,抗温达180℃,抗盐达30%,对密度为1.4~2.0 g/cm³的高密度钻井液在150℃、16 h老化前后流变性能影响较小,并有助于高温高压滤失量的控制。SMJH-1通过物理化学吸附作用和侧向黏附力在钢质表面形成固态膜,增强表面的疏水性,控制流动界面内的固有涡流,减少摩阻压力。该润滑剂在元陆601H和元陆31井进行了试验应用,取得较好的润滑效果。

Abstract: A high density drilling fluid lubricant, SMJH-1, was developed using polyalcohol, long-chain fatty acids with double bonds in their molecules, and natural minerals. SMJH-1 is a high molecular weight ester with ability to reduce extreme pressure friction. Drilling fluids treated with 1%, 2% and 3% SMJH-1 have coefficient of friction reduced by 24.2%, 33.6% and 38.3%, respectively. SMJH-1 functions at 180℃ and in drilling fluids contaminated with 30% salt. SMJH-1 reduces the HTHP filter loss of drilling fluids with density between 1.4 g/cm³ and 2.0 g/cm³, while only slightly affects their rheology. SMJH-1 can spread on the surface of steel, forming a solid film by physico-chemical adsorption and lateral adhesion, hence enhancing the hydrophobicity of the surface and controlling the vortices in the flowing fluid. In this way the friction between fluid and solid surface is reduced. SMJH-1 has been tried in the drilling of the Well Yuanlu-601H and Yuanlu-301, and proved successful.
