摘要
目前塔河油田试井主要采用DPT投捞工艺,但由于井深、原油性质复杂等因素影响,电子脱挂器中途丢手造成井下事故,为此,分析电子脱挂器在塔河油田井况条件下所存在的缺陷。通过7项技术革新,研究一种新型的电子脱挂器并成功应用,解决了长期压恢压降试井井口井控安全的问题,确保了准确录取到各项地层参数。
Currently,in TAHE oilfield,well test for process mainly uses the DPT shots,but because of influencing factors of the well depth and complex crude oil properties,electronic hanging off is released at open hole to cause down-hole accident,therefore,the related technical personnel carefully analyze the deficiency of electronic hanging off instrument in Tahe oilfield under the condition of well conditions.Through seven technical innovations,a new type of electronic hanging off has been studied and successfully applied,solving the longterm wellhead pressure drop pressure restore well test of well control safety problems,ensuring the accurate admission to the formation parameters,which has a popularization and applied value.
