The carbonate reservoir of Halahatang oilfield is high temperature and high pressure, whose fluid properties and flow mechanism are complex, well test curve of it has the characteristics of diversity,complexity and multiple solutions. Current commonly used analytical well test model includes double orifice and double permeability, radial composite type, all having certain limitations application. Binary compound storage model is point to a analytical well test interpretation model at where of a closed reservoir system after a half of seepage boundary, under the condition of quasi steady state flows to the second enclosed reservoir system,its interpretation results show that the beaded structure of the seismic interpretation can be connected to each other under certain conditions. According to the geological characteristics and the seismic data in the study area, the binary composite storage model has a good applicability in the region, which provides a reasonable dynamic parameters and the theory basis for dynamic development in the gas reservoir of this region. © 2016, The Editorial Department of Well Testing.

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.

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.
