超微粉体堵水剂的研究与应用OA北大核心CSCDCSTPCD
Research and application of ultraifne powder water plugging agent
卫城油田深层油藏分层堵水作业中，油藏高压、低孔、低渗的特点对无机颗粒堵水剂性能要求较高，常规无机颗粒堵水剂与超细G级油井水泥易出现超压、强度低或有效期短的问题。针对这些问题，结合超细水泥堵水的技术缺陷，开展了堵水剂体系技术研究。将超细G级油井水泥、超细粉煤灰、活性矿粉和硅粉按照不同的配方比例配制了一系列堵水剂，对堵水剂的流变性、抗缩性和抗压强度等性能进行了室内实验，确定最佳超微粉体堵水剂配方为87.5%超细水泥+7.0%超细粉煤灰+1.5%活性矿…查看全部>>
In separate-layer water blocking operation in deep reservoirs of Weicheng Oilifeld, the characteristics of high reservoir pressure, low porosity and low permeability need a high performance of inorganic particle plugging agent. Conventional water plugging agent of inorganic particles together with ultraifne oil well cement of Grade G may cause such problems as high pressure, low strength and short effective period. In line with these problems and in combinat…查看全部>>
