FIELD: oil producing industry. SUBSTANCE: proposed plant contains the following devices mounted on tubing string: linear with inlet funnel whose lower end is installed not lower than upper limit of productive stratum perforation zone, packer and jet pump with stepped through channel, changeable functional inserts installed in stepped through channel is process of operation of plant, sealing unit with logging cable passed through sealing unit and differential pressure insert and also inserts for physical and chemical treatment of productive stratum and for recording pressure build-up curves with self-contained pressure gauge, sampler and flowmeter. Logging cable is provided with end piece for suspending radiator and receiver-converter of physical fields. Seating appliance with stepped through channel is installed under jet pump in tubing string higher or lower than packer. Maximum diameter of stepped through channel in seating appliance is smaller than minimum diameter of jet pump through channel. Through channel of seating appliance is made for mounting additional linear whose lower end, after installation is seating appliance, is located lower than upper limit of productive stratum perforation zone. EFFECT: improved efficiency as to intensification of stimulation, testing and completion of wells. 3 dwg |
