Type sulfur carbonate reservoir in Tarim seam hole easy to spray easy to leak, the operation risk big, complex test process. In order to ensure the operation safety, reduce drilling cost, improve the efficiency of testing, through the multifunctional cross development, try the well mouth spray tools innovation and development, solve the problem change wellhead of well control, realize the whole process of testing operation safety control. After a lot of field test, has obtained the good application effect. Source

The annulus staged fracturing technology with bottom sealed sandblast perforation by the coiled tubing is a new production measures integrated with sand blasting perforation, hydraulic fracturing, injection annulus sand, coiled tubing drag layer, has advantages of being flexible of transfer layer, high efficiency of operation, clean of wellbore after operation. Based on the analysis of sand blasting perforation, jet fracturing, positioning and transfer layer, characteristics and field implementation process of the annulus staged fracturing technology with bottom sealed sandblast perforation by the coiled tubing is introduced, and taking a test well as an example, the technical process design method and implementation gas been introduced. The test well is completed to 8 stages of sand fracturing in 3 days, nissan gas reaches 35.5×104m3 after fracturing, and increase yield is significantly. ©, 2015, Well Testing. All right reserved.
