摘要:

为满足复杂地层绳索取心钻探技术的需要,寻找、配制了既能代替泥浆具有良好的护壁堵漏性能,又能满足绳索取心钻进技术要求的CL植物胶复合无固相冲洗液。详细介绍了CL植物胶复合无固相冲洗液的配方和配制工艺、性能指标测试与评价、护壁机理认识及应用效果。

Abstract:

To meet the demand of wire-line coring drilling in complicated formation, compound solid-free drilling fluid of CL plant glue was compounded and used instead of drilling mud with the property of wall protection and leaking stoppage. The paper detailed the formula, compounding technology, performance index test and evaluation, borehole wall protection mechanism and application effect.
