摘要:
 高压油气井压井作业易造成地层污染，导致油气井在一段时间内难以恢复到施工前的产能状态，不利于油、气井求产。通过分析不压井作业工程参数，使用不压井作业设备下入水力泵排液测试管柱，只要压力在额定压力之内，即可进行不压井作业下水力泵排液。通过4井次不压井作业现场应用，及对2015年、2016年水平井施工动态数据的收集整理发现，使用不压井作业后，从钻完桥塞开始放喷至下完水力泵排液管柱的平均时间由904 h缩短至190 h。水力泵排液测试中的不压井作业技术可有效减少地层污染，缩短施工周期，是未来测试地层产能的发展趋势。
Abstract:
 The killing operation of highpressure oil and gas wells is easy to cause formation pollution and make it difficult for oil and gas wells to return to the preconstruction productivity state in a period of time, which is not conducive to the production of oil and gas wells. By analyzing the engineering parameters of snubbing operation, using the snubbing equipment to run the hydraulic pump discharge test string, if the pressure is within the rated pressure, the hydraulic pump discharge can be carried out under the snubbing operation. Through the field application of four wells of snubbing operation and the collection and collation of the dynamic data of horizontal well construction in 2015 and 2016, it is found that after using snubbing operation, the average time from the start of blowout after drilling bridge plug to the completion of discharge after run in hydraulic pump string is shortened from 904 h to 190 h. The snubbing technology in hydraulic pump discharge test can effectively reduce the formation pollution and shorten the construction period, which is the development trend of formation productivity test in the future.
