The Qinghai-Tibet Railway runs across the Qarhan Playa (a dried salt-lake) of the Mid-Qaidam Basin, Qinghai Province, and is directly laid on the surface of a rocksalt layer up to 17m in thickness. The rocksalt layer is saturated with concentrated brine in its intercrystalline pores and the depth of the phreatic brine surface is about 0.1-0.7 m. There is a salt-karst zone near the northern margin of the playa owing to the intrusion of unsaturated phreatic and pressure water from the sandy zone outside the playa...

The menace of the salt-karst, particularly of the subsurface karst

察尔汉盐湖干滩地区岩盐岩溶演变和铁路路基基底稳定性的研究和长期监测表明,就路基基底现状而言,隐伏溶洞变化极其缓慢,岩盐地层具有足够的承载能力,以稳态蠕变的方式缓慢下沉,可以长期保持铁路主干线的稳定性。然而,盐湖卤水矿床的大规模开采以及其它人为因素的影响将可能加速溶洞的发展,威胁铁路的安全。建议采用基底的异常下沉速率和隐伏溶洞的危险洞顶盐厚,作为路基基底稳定性长期监测的两项安全指标。

The conventional approach to avoid stuck in salt formation is to use high density saturated brine mud. This approach may be effectual in some low in situ stress and low temperature salt formation, but can not prevent from tight hole in high in situ stress and high temperature salt formation. In addition, it is impractical to increase mud weight too much in drilling practice because mud lost may be induced in weak sand. A new way is presented to control tight hole in high in situ stress and high temperature...

The conventional approach to avoid stuck in salt formation is to use high density saturated brine mud. This approach may be effectual in some low in situ stress and low temperature salt formation, but can not prevent from tight hole in high in situ stress and high temperature salt formation. In addition, it is impractical to increase mud weight too much in drilling practice because mud lost may be induced in weak sand. A new way is presented to control tight hole in high in situ stress and high temperature salt formation by low density unsaturated brine mud. The salt solution rate can be controlled by adjusting content. If the balance between salt solution rate and hole shrinkage rate is established, stuck can be avoided successfully. The technique is used successfully in field.

防止盐岩卡钻传统的措施是采用饱和盐水泥浆 ,阻止盐岩溶解 ,加大泥浆密度 ,减缓盐岩向井眼方向的流动 ,防止缩径。但这种以提高泥浆密度为前提的盐层钻井在高温、高地应力区域 ,不能从根本上解决盐岩层卡钻的问题 ,因为实际钻井中泥浆密度不能无限制地增大 ,否则其他岩性层段易产生复杂情况 ,并且影响钻速。提出了解决这类问题的新方法 ,采用适当密度的欠饱和盐水泥浆 ,通过调整氯根 (Na Cl浓度 ) ,让欠饱和盐水泥浆能满足井眼截面的盐溶解速率与盐层的缩径率平衡 ,从而达到防止盐岩卡钻的目的 ,并在实际钻中得到较为有效的应用。

The influence of temperature and volume fraction on dissolution velocity of carbonate rock was studied by simulation tests, and another analysis was performed to determine the effects of preceding factors on enlargement ratio of borehole. In order to effectively control both of them, this paper presents new relational equations under different temperature and advisable proposals.

通过盐岩井眼溶解速率模拟试验,研究了温度、钻井液中盐的体积分数对盐岩溶解速率的影响,进而分析了温度、钻井液中盐的体积分数对井径扩大率的影响,建立了不同温度下,钻井液中盐的体积分数与盐岩溶解速率、井径扩大率的相关关系方程,并提出了控制盐岩地层控制井眼溶解速率的合理建议。
