| Abstract: | The elastic flow regime of stratal fluids has been well studied in the literature 1, 2] and the results have been widely applied in practice in the development of oilfields 3, 4]. Consideration is given below to the new problem of the reduction in the output of a well at fixed well-bottom pressure after it has been operating for some time at constant output. There is a practical aspect to this sort of problem. For instance, the degassing of the reservoir in the region of the well is considered an undesirable feature in the exploitation process. If degassing begins, the resistance to flow grows sharply and the well outputs fall considerably. Once the well-bottom pressure has fallen to the saturation pressure, it must not be allowed to fall further, or gas will be given off in the well region of the reservoir. It is desirable to keep the well-bottom pressure higher than the saturation pressure.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 82–87, March–April, 1985. |
