Description

В пробуренную оквахиву, ааполневвув гдинио ым раотвороы, на нвоумх срубах опуокак металлическую трубу, наружный диаметр которой равен проектному диаметру окважины в овету. Внутри неоущей труби коакоиально уотанавливают еце одну трубу, нижний конец которой жеотко укреплен в неоуцей трубе. Неталличеока труба оопр жена о неоущей через желеаобетоавую перегородку о вотроеншш обратным клапаном. К клапану подведена труба, коаиоиахьно уотавовленва в веоущай. Иеталличеока труба онабжена двум фовар ми, нижними и верхними, преднааначеншша дл ее центрировани . Один иа фоварей выполнен оммвым.In the drilled hole, on the bottom of the barrel, on the bottom of the log cabins there is a metal pipe, the outer diameter of which is equal to the design diameter of the well in the jacket. Inside the neo-carrying pipe, one pipe is coaxed down the etsa, the lower end of which is fixed in a neootsey pipe. Netallichoka pipe oopr about the neuavshuyu through the zheaaobtotoavuyu partition of the armature check valve. A pipe has been connected to the valve, which is coaxially injected. The metallochek tube was equipped with two Fovars, upper and lower, intended to center it. One of them is made by ommvy.

Ниже другого фонар в Heoyiva трубах вварены несколько патрубков. В верхней чао«м меташичеокой трубы , ааподшцо о ее наружной поверхвоотм, вмовтировавы три пары вхектродов, изолированных друг от друга и от тела и соединенных кабелем о приборами на поверхвоо и.Below another lantern in Heoyiva pipes are welded several connections. In the upper chao "m of the metachic tube, and on the outer surface of the tube, there are three pairs of heterodes isolated from each other and from the body and connected by a cable to the instruments on the top and the outside.

Ооолв опуокани маталличеокой трубы до аабов оквмшны по труб, уотановленной внутри неоуцай трубы, вначале прокачивают гаивиотый раотвор дл аромывки окваживы, а затем цемавтвый раотвор. Пооледввй вытеон ет гликвц хый раотвор из полоотв трубы в заполн ет чаоть затрубвого проотранотва. Потом прокачивание цемевтвого раотвора прекрацаш в по трубе пропускает воздух, КОТ01ШЙ вытесн ет цемавтвый раотвор.The oolol of the pipe of the metal pipe before the aabs are filled with pipes that have been embedded inside the neo-pipe, first pump the haiviromator for the filling of the pipe and then the cement for the artist. Lastly, the glycol working man from the polotvov pipe in fills the tea of the annular prootranotv. Then the pumping of the cement razvora stopped in the pipe passes air, KOT01ShY displaces the cement ramator.

В захрубноы проохранствв цеиенгщй раствор подвшаехе выше, но не должен доходихь до уровн зыходныаеотхерсткй патрубков. После охвахыванм цеыенхного раствора дат нах г несущим хрубаи, одаоврвкенно прокаша 10ДУ по 1нухреннвй грубе. Вс конструкци начинает пвреиещагьв вверк, а вон й фонарь останетс зацеиентнрованнын в скввжино. Но несущим трубаы лрвкачнваот цеиантный раствор, который через патрубки будет поступать в эатрубное пространство, образу крепление сквахиаы. Скорость продвижени трубы должна быть такова, чтобы цеыентный раствор успел схватитьс до того, как нижний срез металлической трубЬ пройдет данное сечение скважины.In addition, there is a higher level of solution in the substrate, but it should not be at the level of each impaired pipe. After scooping up a solution of dates dah g carrying the hrubay, prodded 10D in perfect harmony in a single rough coat. The whole structure begins to be rescued and the lantern remains centered in the squash. But the carrier pipes of the lvkachnvot are made of a solvent solution, which through the pipes will flow into the pipe space, forming the attachment of a squahiah. The rate of advancement of the pipe must be such that the cement solution will have time to grab before the lower section of the metal pipe passes this section of the well.

Электроды испольаувхо в качества чувствительных аленентов дл диcтaн циовного замера уровн цементного раствора в затрубном пространстве по способу электрического сопротивлени .Electrodes are used as sensitive alentent for the distance measuring of cement mortar level in the annulus by the method of electrical resistance.

Claims

1. The method of fastening wells of large diameter, with a PM that, in order to create an annular cement wall in the well,

on the latter, a formwork consisting of a metal pipe is lowered onto the pipes, and the pipes that are concentrically inserted into the pipes force cement into the annular space and after the start of cement setting begins, the formwork is raised to a height equal to the height in the annular space of the injected cement, during which the formwork is fed through the load-bearing pipes, pumping a new portion of cement through the channels into the annular space above the initially injected cement, repeat this operation until the wellhead.

2. A device for carrying out the method according to claim I, characterized in that it consists of a formwork in the form of a metal pipe that is coupled to a carrier pipe through a reinforced concrete partition, with a check valve to which the pipe is connected in the center of the latter.

3. A device according to claim 2, characterized in that it is provided with two lamps designed to center the formwork, one lamp being made removable in order to leave it in the cement mass when lifting the formwork.

4. The use of devices on PP. 2 and 3 electrodes, ring-shaped embedded in a pipe, are aimed at “interlocking as sensory aleevts for distant measurement of level according to the method of electrical transmission.
