Description

Отличие забойного регистратора давлени  дл  измерени  и записи давлени  на забое скважины заключаетс  в выполнслии его в виде шлицевого переходника и гидравлической камеры, расположеш-ой над колонковой трубой., через которую передаетс  давление колоиког.ой трубе, а дл  записи изменени  давлени  жидкости в каморе барабан с часовым механизмом и картограммой. Такое выполнение .забойного регистратора ис1С1ючает вли ние искривлени  скважшч и других факторов, поглощающих часть передаваемого давлени  на его показани .The difference between the downhole pressure recorder for measuring and recording the pressure at the bottom of the well is in the form of a spline adapter and a hydraulic chamber located above the core pipe, through which pressure is transmitted to the colliohous pipe, and to record the pressure of the fluid in the chamber the drum with clockwork and cartogram. This embodiment of the borehole recorder examines the effect of well curvature and other factors that absorb part of the transmitted pressure on its readings.

На чертеже изображен забойны регистратор давлени , в продо. ьном разрезе.The drawing shows a pressure logger, in the form. not a cut.

Описываемый забойный регистратор даатени  представл ет собой цилиндрический корпус в виде отрезка трубы / с двум  переходни.хсми: верхним 2 и нижним 3. Верхний переходник выполнен с подвижной щлицевой частью, котора  посредством резьбы соединена с колон-ю; бурильных труб, а внизу заканчиваетс  поршнем 4. Он передает крут щий момент от бурильных труб корпусу 1, не передава  давлен 1 . 11ижний переходник предназначен дл  соединени  с колонковой трубо ; 5. оканчивающейс  коронкой 6. Над колонковой трубой расположена гидрокамера , в верхней части которой находитс  цилиндр 7, наполненимй жидкостью. Внутри цилиндра 7 перемещаетс  поршень 4. Б нижней части гидрочаме.ры расположен барабаи 8 с часовым меха1Н змом н карTorpaMN:ou .The described daeten downhole recorder is a cylindrical body in the form of a pipe section / with two transitions: upper 2 and lower 3. The upper adapter is made with a movable slit part, which is connected to the column by means of a thread; the drill pipes, and at the bottom ends with a piston 4. It transmits the torque from the drill pipes to the housing 1, without passing on the pressure 1. The 11-way adapter is designed to connect to the core pipe; 5. ending with a crown 6. Above the column tube is a hydrochamber, in the upper part of which there is a cylinder 7, filled with liquid. Inside the cylinder 7, the piston 4 is moved. At the bottom of the hydrochip, there is a drum 8 with a clockwork of a snorkel frame: TorpaMN: ou.

Создающеес  в процессе бурени  давление на забое через поршс;;ь передаетс  жидкости и измер етс  плун.жерным манометром или трубкой Бурдона (на чертеже не показаны) с последующе записью на картограмме барабана при помощи поводка 9 с элсктрокарандащом.The pressure created at the bottomhole during the drilling process through the pistons; is transferred to the fluid and measured with a plunger pressure gauge or a Bourdon tube (not shown) and then recorded on the drum cartogram with the help of a leash 9 with an electric strap.

Предмет изобретени Subject invention

Забойный регистратор давлени  длй измерени  и записи давлени  на забое скважины, отличающийс  тем, что, с целью исключени  вли ни  искривлени  скважины и других факторов, поглощающ:1. часть передаваемого давлени  на его показани , регистратор вылолйен в виде шлицевого переходника и гидравличсско камеры, расположенной над -колонковой трубой, через которую передаетс  давление колонковой трубе, а дл  записи изменени  давлени  жидкости в камере применен барабан с часовым механизмом и картограммой.A downhole pressure recorder for measuring and recording downhole pressure, characterized in that, in order to eliminate the effect of curvature of the well and other factors, it absorbs: 1. part of the pressure transferred to his readings, the recorder is cast out in the form of a spline adapter and a hydraulic chamber located above the column pipe through which the pressure of the core pipe is transmitted, and a drum with a clock mechanism and a cartogram is used to record the change in fluid pressure in the chamber.
