Research Of Incremental Yield Technology For Oil-well High-energy Composite Perforating/propellant Hole

The character of some oil well prospecting, but now study on the fracturing conditpressure crack methods was discussed, then a new pressure crack technology was introduced, it is High-energy composite perforating/propellant hole. Two different property high-energys were combined in the High-energy composite perforating/propellant hole technology. Lighting a fire at one time but making work at two different times. HEPF technology highly increased the seepage area and prolonged the lengths of the cracks. The over-positive pressure gas can eliminate the compact damage derived from general perforating hole and increase the permeability, therefore don't need to wash the oil under minus pressure. Compared with the other two methods of hydraulic fracturing and general perforating hole, HEPF is simpler in technology and more significant in effect and safer, which is suitable to industrial manufacture.The HEPF technology has powerful ion under the action of the deflagrating gas are lack. The forming and the extending of the crack will cause the variation of the gas pressure, in this paper our main purpose is to utilize the ideal-gas equation to compute out the variation...
