为了给井下高压水力压裂提供可靠的硬件支持,提高水力压裂增透卸压效果,研发了BYW78/400型井下高压水力压裂泵组,该泵组便于井下运输安装,可远程监视及远程控制,满足了井下煤岩层高压水力压裂增透卸压的要求。现场应用表明,泵组工作性能稳定,各项指标均达到了现场压裂要求,增透卸压效果显著,为提高井下高压水力压裂效果提供了可靠的硬件条件。
In order to provide reliable hardware support for underground high-pressure hydraulic fracturing and improve the effect of hydraulic fracturing and pressure relief, a BYW78 / 400 downhole high pressure hydraulic fracturing pump set was developed. The pump set is convenient for underground transportation and installation and can be remotely monitored and remotely Control, to meet the underground coal seam high pressure hydraulic fracturing pressure relief requirements. The field application shows that the working performance of the pump set is stable and all the indexes meet the requirements of on-site fracturing. The effect of pressure relief and pressure increase by the permeation is remarkable, which provides reliable hardware conditions for improving the high-pressure hydraulic fracturing in the well.
