ＦＤ９６是一种酚醛树脂基堵剂，地面粘度很低，在适宜的ｐＨ（９—１１）和温度（６０—１１０℃）下可在３１．５—４．２小时内固化，固结物致密，对岩芯的封堵能力很强。本文报道了该堵剂的组成，合成诸因素对堵剂性能的影响，堵剂抗盐抗钙和抗油污染的能力，岩芯封堵能力，在中原油田七个断块应用该堵剂封堵油、水井高出水层和套管漏失取得的良好效果。 FD-96 is a phenolic resin based plugging agent, the ground viscosity is very low, at a suitable pH (9-11) and temperature (60-110 ℃) in 31.5-4.2 hours curing, consolidation Material tight, plugging ability of the core is very strong. This paper reports the composition of the blocking agent, the influence of synthetic factors on the performance of the blocking agent, the ability of the salt to resist calcium and oil contamination of the blocking agent and the plugging ability of the core, and applies the blocking agent to seven blocks in the Zhongyuan Oilfield Blockage of oil, wells higher than the water and casing leakage achieved good results.
