【摘要】：針對(duì)魯克沁中區(qū)油藏非均質(zhì)性嚴(yán)重、水油流度比大和地層水礦化度高的特點(diǎn),研究了疏水締合聚合物AP-P8在該油藏條件下的黏度、溶解性、抗剪切性和熱穩(wěn)定性,考察了AP-P8的驅(qū)油性能,并在現(xiàn)場(chǎng)進(jìn)行了應(yīng)用。研究結(jié)果表明,配液水為注入水(礦化度約80 g/L)、溫度為78℃時(shí),AP-P8的增黏性能明顯好于常規(guī)聚合物,AP-P8溶液黏度隨溫度升高而降低,用注入水配制的2 g/L AP-P8溶液在100℃時(shí)的黏度為64.5 mPa·s;室溫下AP-P8在注入水中的溶解性較好,溶解時(shí)間為2.8 h;AP-P8抗剪切性較好,2.5 g/L AP-P8溶液剪切后的黏度保留率為54.2%。隨AP-P8濃度的增加,巖心阻力系數(shù)和殘余阻力系數(shù)增加,有利于提高原油的采收率;AP-P8可在水驅(qū)基礎(chǔ)上提高稠油采收率10.2%;現(xiàn)場(chǎng)試注試驗(yàn)結(jié)果表明,AP-P8的注入性良好,常溫配液黏度為100 mPa·s,注聚穩(wěn)定壓力27.5 MPa。AP-P8滿足魯克沁中區(qū)油藏條件對(duì)聚合物驅(qū)性能的要求,應(yīng)用時(shí)可以直接用注入水配液。
[Abstract]:In view of the serious heterogeneity, high water / oil mobility ratio and high salinity of formation water in Lukeqin middle area, the viscosity, solubility, shear resistance and thermal stability of hydrophobically associating polymer AP-P8 in this reservoir are studied. The oil displacement performance of AP-P8 was investigated and applied in the field. The results show that the viscosity of AP-P8 is better than that of conventional polymer AP-P8 when the salinity is about 80 g 路L ~ (-1) and the temperature is 78 鈩，
