Research of tight gas reservoir simulation technology

Abstract

The stimulation of tight gas reservoir in Linxing block of Shanxi Province has always been a difficult problem. This paper describes and analyzes the formation lithology, physical properties and sensitivity of the reservoir. And introduces the pulse power technology and controllable shock wave technology, and focuses on the research and analysis of the latter. The results of field test show that: In the application of plug removal and permeability enhancement of low permeability tight gas oil and gas wells in medium and shallow wells (well depth less than 3000m), the controllable shock wave technology has achieved good results in increasing production and injection. Field application shows that the technology is basically mature and can be further promoted. Compared with traditional technologies such as acidizing and plugging removal, controllable shock wave technology has the advantages of layered implementation, strong pertinence, simple operation, wide adaptability and better effect.
