摘要
综述了裂缝性储层保护技术与钻井完井液方面国内外的研究进展,论题包括裂缝性油气藏分类,应力敏感性评价、裂缝宽度预测、损害机理、暂堵机理、钻井完井液。指出许多问题有待探索:①应力敏感性和闭合滞后效应评价方法;②有效应力条件下裂缝宽度的实用性预测模型;③损害机理和保护机理;④保护裂缝性储层的切实可行的钻井完井液体系。参51。
The recent progress in protective methods, techniques, and technologies and in drilling/completion fluids for fractured oil and gas reservoirs is reviewed in topics including fractured reservoir classification, reservoir stress sensibility evaluation, fracture wideness estimation, formation damaging and temporarily plugging mechanisms, and drilling/completion fluids. The problems still to be solved are： methods of evaluating reservoir stress sensibility and fracture closure hysteresis effect; practical predicting models for fracture wideness under effective stress; mechanisms involved in formation damage and protection; practicable reservoir protecting drilling/completion fluids.
