-
摘要: 现有常规桥浆堵漏材料存在裂缝适应性不强、封堵层浅和堵漏成功率较低等问题。为此，优选了不同规格弹性孔网材料，进行了压缩回弹性、抗拉强度和抗温性等性能评价试验，优选了综合性能最佳的弹性孔网材料，并考察了弹性孔网材料尺寸、形状和加量对堵漏效果的影响。试验结果表明，1#弹性孔网材料的50%压缩永久变形率低于10%，抗拉强度为150 kPa，抗温能力达150 ℃，适合用作堵漏材料；正方体形弹性孔网材料可滞留在裂缝内，堵漏效果较好，尺寸为5.0 mm×5.0 mm×5.0 mm的弹性孔网材料对尺寸为5.0 mm×4.0 mm的楔形缝封堵效果最优；弹性孔网材料加量为0.08%时的堵漏效果最好。弹性孔网材料在多口井进行了现场堵漏，一次堵漏成功率达86.7%。研究表明，弹性孔网材料对裂缝性地层具有较好的适应性和堵漏效果，能够解决地层漏失问题。Abstract: The existing conventional bridge slurry plugging materials have problems such as weak fracture adaptability, shallow plugging layer and low plugging success rate. For this reason, different specifications of elastic mesh materials were selected for evaluation tests of compressive resilience, tensile strength and temperature resistance, and the one with the optimal performance was identified. In addition, we investigated the influence of sizes, shapes and concentrations of the elastic mesh material on plugging efficacy. Experimental results indicate that elastic mesh material marked No.1 is suitable for plugging, due to its low permanent compressive rate of 10% at 50% of its compressive strength, high tensile strength of 150 kPa and high temperature resistance of 150 °C. The cubic elastic mesh material can remain in fractures, and thus presents excellent performance in plugging. The elastic mesh material in the size of 5.0 mm×5.0 mm×5.0 mm has the best plugging performance in wedge-shaped fracture in the size of 5.0 mm × 4.0 mm. In addition, the optimal concentration of the elastic mesh material is 0.08%, and the success rate of one-time plugging has reached 86.7% after the elastic mesh material has been applied in multiple wells. The research demonstrated that the elastic mesh material has good adaptability and plugging effect for fractured formations, and can solve the problem of lost circulation.
