摘要

摘要: 伊拉克米桑油田Abu区块储层岩性为碳酸盐地层，缝洞非常发育，而且地层压力系数低，漏失是钻井过程面临的主要难题。结合相关地质取心和电测成像资料，在总结分析前期堵漏工艺的基础上，室内对现有可酸溶复合堵漏材料配方进行了优化，将酸溶率提高到75%以上，室内模拟实验承压能力提高到7 MPa以上，并进一步优化形成了适应该区块的堵漏施工工艺。通过现场5口漏失井的试验表明，优化后的可酸溶堵漏配方明显提高了现场堵漏成功率，进一步缩短了钻井周期。

Abstract: Carbonate reservoirs in the Block Abu, Missan Oilfield (Iraq) are full of fractures and vugs and are of low formation pressure. Mud losses have been the main problem encountered in drilling operations. Based on the summary of previous mud loss control techniques, an acid soluble compound lost circulation material (LCM) formulation was optimized under the help of logging data and electric imaging logging data. The acid dissolution rate of the optimized compound LCM was increased to above 75%. In laboratory simulation test, the pressure bearing capacity of the optimized compound LCM was increased to 7 MPa. Techniques of using the LCM were also optimized. This compound LCM was used on 5 wells in the Block Abu, and the success rate of mud loss control was evidently increased, further cutting down drilling time.
