摘要

摘要: 针对元坝地区海相碳酸盐岩地层井下常遭遇酸根及硫化氢污染，造成钻井液黏度和滤失量上升、抗温性下降，流型难以控制，给现场维护带来极大挑战。提出采用生物-化学的方法对木质素进行改性，研制出一种团状多支结构的环保型生物质合成树脂降滤失剂LDR。性能评价结果显示，该产品抗温达200 ℃，抗盐25%，抗钙3000 mg/L，表现出较强的耐温抗盐的性能，并以此为核心抗高温材料，通过引入钾、钙、钠等离子，构建出抗高温复合盐水钻井液体系。在元坝地区现场应用2口井，现场应用表明，在元坝X-701井钻井液最高密度为2.34 g/cm³，电测显示温度为157 ℃，酸根含量达21 157 mg/L，该体系依然具有良好的流变性，抗污染能力强，两趟电测均一次顺利到底，连续静止7 d返出钻井液黏度48 s，仅用28.88 d完成了侧钻任务。该体系的成功应用，标志着生物质资源在高温高密度钻井液中取得新的突破，满足了高温小井眼对钻井液的需求，对元坝地区深井、超深井具有较好的指导借鉴意义。

Abstract: In view of the fact that the marine carbonate formation in Yuanba area is often polluted by acid radical and hydrogen sulfide, which causes the viscosity and water loss of drilling fluid to rise, the temperature resistance to decline, and the flow pattern to be difficult to control, bringing great challenges to on-site maintenance. In this paper, a bio chemical method is proposed to modify lignin to develop an environment-friendly filtration reducer LDR of biomass synthetic resin with a cluster multi branch structure. The performance evaluation results show that the product has a temperature resistance of 200 ℃, a salt resistance of 25%, and a calcium resistance of 3,000 mg/L, showing a strong temperature and salt resistance performance. With this as the core of the high temperature resistant material, a high temperature resistant composite brine drilling fluid system is constructed by introducing potassium, calcium, and sodium plasma. Two wells were applied in Yuanba area. The field application shows that the maximum density of drilling fluid in Yuanba X-701 well is 2.34 g/cm³, the electric measurement shows that the temperature is 157 ℃, and the acid radical content is 21,157 mg/L. The system still has good rheological property and strong anti pollution ability. The two electric measurements successfully reached the bottom at one time, and the drilling fluid viscosity returned for 48 s after 7 consecutive days of standstill. It only took 28.88 days to complete the sidetracking task. The successful application of this system indicates that biomass resources have made a new breakthrough in high-temperature and high-density drilling fluid, effectively meeting the requirements of high-temperature slim hole for drilling fluid, and has good guidance and reference significance for deep wells and ultra deep wells in Yuanba area.
