| 摘 要： | 煤田钻探中,经常会遇到比较破碎、易坍塌、易水化膨胀等复杂地层,给钻进造成较大的困难。开发了具有良好的防塌性能、较好的抑制性并具有适当密度的高密度低失水泥浆体系。现场使用证明,该泥浆体系在煤田小口径金刚石绳索取心钻探中能很好维持孔壁稳定、有效抑制泥页岩的水化膨胀,降低孔内事故的发生率。

| Abstract: | It is very difficult in the coalfield drilling process because rather complex strata are usually encountered;such as breaking layer,collapsing layer and hydration expansive layer.Heavy density and low filtration drilling fluid system were developed with anti-sloughing,inhibiting and proper density.Field application proves that the drilling fluid system can perfectly maintain borehole stability and effectively inhibit the hydration expansion of mud stone and shale with the accident rate in wire-line coring drilling decreased. |
