In the DRILLING PROCESS, the nyfelle rubber element 14, the nut 15 jtviH interacts with the barrel 12, the locking washer 16. The layout ends with the drill bit 17. Before the device is lowered into the roof of the open formation, the drill hole is sumped for the length of the drill bit with a diameter less than the main shaft less than the main shaft than the main shaft with a drill hole the length of the drill bit is less than the main shaft than the main shaft of the drill hole The locking washer 16 to the load on the weight of the tool through the nut 15, rigidly connected to the pipe 11, is transmitted to the rubber element 14, as a result, the rubber element 14 is compressed and the safety valve is sealed from the wellbore. Valve 6 is then discharged into the pipes and flushing fluid is injected. The pressure of this fluid valve 6 and the sleeve 9, which serves as a seat for the valve 6, move without opening the windows to the nozzles 5. At the same time, the windows in the sleeve 9 are aligned with the windows in the housing 2. При работе струйного насоса осуще ствл етс  подсос жидкости из-под пакёрнбго пространства, чёрёз0kна- и клапаны 8 в камеру смешени  и через диффузор в затрубное пространство.

Источники информации, прин тые ., во внимание при экспертизе 1. Патент США 3107729, кл.166-66, 1963.2. During the operation of the jet pump, liquid is sucked out from under the pakernbgo space, the exhaust valve 8 and into the mixing chamber and through the diffuser into the annulus space. Behind . This creates a pressure difference above and below the packer, which ensures that the additional pressure element is pressed against the wellbore. By turning the drillstring to the right, the nut 15, having a band thread, turns away from the barrel 12, and the picker remains under the action of only a hydraulic load. ; The rift is carried out on the length of the pipe 11, at the bottom of the hole. due to the constant suction of fluid, a depression is maintained, due to which the fluid comes in from the reservoir, cleansing the sludge and removing particles from the formation. After drilling is completed, the tool is lifted from the bottom, and the mud pumps are turned off. Hydrostatic pressure from the annulus through the diffusers and the mixing chamber is transferred to the suction chamber and presses the valves 8 to their sockets. The packing space is isolated from the annular, and the depth gauges record the pressure recovery curve. At the end of the reduction of pressure in the pipes, the Safety Device is lowered onto the cable, with which the valve 6 is captured together with the sampler and removed to the surface. The invention of a device for investigating a formation during a drilling process, comprising a drill shell, a packer placed on a drill string, comprising a barrel with a sealing element, a submersible jet pump and a sampler, so that creating pressure drop; E {Linazg1 Narrower on the packer during the research of the ITT in the depression mode, the drill string is equipped with the branch pipe forming the annular cavity with the check valve and the nut installed for the interactions Twi packer with the barrel, wherein a jet pump is installed in the annular space above the check valve.
