COMBINED PROCESS OF APPLICATION AND ANALYSIS OF PERFORATING, TESTING AND ACIDIZING

Aimed at the problems of high mud content, long period for well completion and modification in calcium formation, and well control fluid easily damaging formation, the article developed this combined process with perforating, testing and acidizing. This process utilizes combined pipe string to realize perforating, testing and acidizing operation in one time. Site application shows that it promotes efficiency of well completion and formation modification, and avoids the formation damages from well control fluid. For expanding its applicable range and circumstance, aimed to the experience of construction process, the study designs several kinds of combined pipe string and construction plan of perforating, testing and acidizing.
