摘要

摘要: 针对漏失及恶性漏失的堵漏工作,研制的特种凝胶ZND在实际应用中取得了显著的成绩,但是对于恶性漏失堵漏用的凝胶,没有一套合适的仪器及方法来规范其性能指标,因此研制了一台具有高精度的新型启动压力装置,并得到了相关的启动压力评价方法——液位-压力曲线。通过液位-压力曲线,可以确定凝胶在模拟地层中的启动压力,并能够判断相同启动压力情况下凝胶的性能优劣。

Abstract: ZND, a special gel has recently found a wide use in controlling mud losses. This paper discusses a novel instrument used for the evaluation of ZND, and a method of measuring the start-up pressure of ZND-liquid level-pressure curve method. By plotting the liquid level versus pressure, this high-precision instrument can be used to determine the start-up pressure of ZND in simulated formation conditions, and the performance of gels at the same start-up pressure.
