Study on Physics Properties of ESPCP Stator Rubber with Oil Erosion
For studying physical properties of Nitrile Butadiene Rubber(NBR) stator of Electrical Submersible-motor-driven Progressive Cavity Pumping (ESPCP) with oil erosion,two different formulations of NBR soaked in crude oil at 90 ℃ for 168h.Variation rule with time of rubber quality,hardness,volume,tensile strength and elongation rate are got.The results show that erosion in the same temperature,rubber quality increase rapidly in the first 24h,increase slowly down in 24~168h.Rubber hardness does not change significantly soaked within 168h.Rubber volume change obviously in the first 72h and change slowly in 72~168h.In the first 96h,the rubbers tensile strength and elongation rate change quickly,slowly changes in 96~168h.The study has a certain reference of design of ESPCP stator under certain operating conditions.
