Ultra-high Temperature Water Base Drilling Fluid

No. 462 Zhongyuan Lu, Puyang city, Henan 457001, China

摘要

摘要: 通过引入抗高温降滤失剂MP488、高温流型调节剂CGW-6,使超高温钻井液流变性得到控制,通过采用抗盐高温高压降滤失剂HTASP-C,使超高温钻井液高温高压滤失量得到有效控制,形成了抗温达260 ℃、密度为2.35g/cm³ 的淡水钻井液配方,并对其进行了抗温机理分析和性能评价。结果表明,该淡水钻井液抗NaCl 污染可达饱和,页岩滚动回收率达94.1%,抗钻屑、膨润土污染能力强,具有良好的沉降稳定性,在密度为2.0～2.5 g/cm³ 时表现出较好的适应性,能够满足钻井液抗温260 ℃性能要求。

Abstract: An ultra-high temperature water base drilling fluid was prepared with high temperature filter loss reducer MP488, high temperature rheology stabilizer CGW-6 and high temperature filter loss reducer HTASP-C with good salt tolerance. The drilling fluid, having density of 2.3 g/cm³, was able to tolerate salt (NaCl) contamination to saturation, and percent recovery of shale sample in hotrolling test of was 94.1%. It also had good suspension capacity and tolerance to clay contamination. This drilling fluid was suitable for use in high temperature (260 ℃) well drilling, with its density being adjusted between 2.0 g/cm³ and 2.5 g/cm³.
