Study and application for new model DST straddle perforation and testing combination technology
Keywords:
Drill stem test, Overall benefitAbstract
The new model DST straddle perforation and testing combination technique is a comprehensive testing method to conduct perforation and test to destination zone with straddle ways which uses two packers without setting bridge plug or injecting cement plug to isolate bottom layers. The features of that sequence of zones being operated can be selected at random and reducing quake system and releasing equipment for instantaneous high pressure caused by donating guns can protect down hole tools effectively can raise testing efficiency and reduce its cost.
