摘要:
 

常规地层测试排液联作技术劳动强度大、作业周期长、施工费用高。采用双封跨层方式，上部储层排液后，投

球关闭常开阀，智能地层测试阀按预设控制程序自动开启下部储层，在充分考虑射流泵排液工序的基础上，形成智能分层射流泵排液技术。该技术在华北油田XL901X井现场应

用，204 h后智能地层测试阀自动开井，泵排期间监测压力未降，测试阀和滑套密封良好。利用“两阀两封”实现一趟管柱、两层排液的目的，减少一次洗压井作业，提高了

作业时效，有效保护了油气层；同时下入双压力计，验证了两层间无串通，实现了不动管柱分层测试排液的目的，为多层快速试油提供了技术支撑。

Abstract:
 

Conventional combination technology of formation testing and discharge has the

characteristics of high labor intensity, long operation cycle and high construction cost. The doublesealing crosslayer operation method is adopted,

when the discharge of the upper reservoir is completed, the ball is thrown to close the constantly open valve, and the intelligent formation test valve

automatically opens the lower reservoir according to the preset control program. Based on fully considering the discharge process of jet pump, the

intelligent stratified jet pump discharge technology is formed. The technology was applied in well XL 901x of Huabei Oilfield. After 204 hours, the

intelligent formation test valve automatically opened the well, the monitoring pressure did not drop during pump discharge, and the test valve and

sliding sleeve were well sealed. This technology can realize discharging of two layers using one trip string and “two valves and double seals”, which

can reduce one time of well washing and killing operation, improve the operation efficiency, and effectively protect the oil and gas reservoir. In

addition, double pressure gauges are installed to verify that there is no channeling between the two layers, so as to realize the purpose of layered

test and liquid drainage without moving string, which provides technical support for multilayer rapid oil testing.
