吐哈油田属低渗、特低渗型油田 ,压力系数普遍较低 ,地层易受污染 ,试油试气工作难度较大。在试气工作中结合各井地质特点 ,大力推广应用先进的射孔、测试、改造和气层评价等技术 ,逐步摸索出一套适合吐哈地质特点的科学试气配套工艺技术 ,在 30层的试气实践中 ,取得了较好效果 Turpan-Hami Oilfield is a low-permeability and extra-low permeability oilfield. The pressure coefficient is generally low and the formation is easily polluted. Therefore, it is more difficult to test oil and gas. Combining the geological features of each well in the trial gas work, we vigorously popularize and apply advanced techniques such as perforation, testing, alteration and gas reservoir evaluation to gradually develop a set of scientific trial gas supporting technologies suitable for geological features of Tuha. At the 30th floor Test gas practice, achieved good results
