摘要

摘要: 为了解决大庆油田齐家-古龙区块页岩油水平井井壁失稳的问题，对古龙区块地质特征、施工难点和失稳机理进行总结分析。针对施工中遇到的井壁稳定、钻井液流变性控制、井眼净化等油基钻井液技术难题，提出相应的技术对策。优选SFD-1、无荧光防塌剂BY和Soltex等关键封堵处理剂，并对目前使用的油包水钻井液配方进行优化和室内评价。实验结果表明，优化后的钻井液具有良好的性能，高温高压滤失量小于3 mL，抗岩屑侵可达30%。该钻井液技术在大庆油田古龙区块^**2HC井进行现场试验，施工顺利，井下无复杂事故发生，能够解决长水平段井眼失稳问题，在大庆油田页岩油勘探开发中具有应用前景。

Abstract: In this paper the geological characteristics, operation difficulties and mechanisms of borehole wall collapse of the Gulong block in Daqing Oilfield are summarized and analyzed in an effort to solve the borehole wall instability problem encountered in shale oil horizontal drilling in the Qijia-Gulong block. Different measures have been presented to solve different problems encountered for the use of oil base muds, such as borehole wall stabilization, mud rheology control and hole cleaning. Key plugging agents such as SFD-1, non-fluorescent anti-collapse agent BY and Soltex were selected for use in the oil base (water-in-oil) drilling fluid that was used in the past and was now optimized. Laboratory evaluation tests showed that the optimized oil base mud has HTHP filter loss of less than 3 mL and is resistant to the contamination from 30% drilled cuttings. Filed application of this mud on the well ^**2HC in the Gulong block was successful and no downhole troubles have ever happened during drilling. The optimized oil base drilling fluid can be used to solve borehole wall collapse problem encountered in long horizontal drilling, and will have broader prospects of application in shale oil exploration and development in Daqing Oilfield.
