Description
(54) УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ЭЛЕКТГОСТАБИЛЬНОСТИ ЭМУЛЬСИОННЫХ БУРОВЫХ РАСТВОРОВ(54) DEVICE FOR DETERMINING THE ELECTRIC STABILITY OF EMULSION DRILLING SOLUTIONS
Сатурн 1,5 В, Марс 1,5 В, Крона 9,0 и т.д. При малых зазорах между электродами (например, 100 мк)Возникают высокие напр женности электрического пол пор дка 100-1000 В/см при напр жени х на электродах в 1-10 В соответственно. При определенных напр женност х электрического пол между электродами происходит пробой эмульсии и ее разрушение, которое наблюдаетс визуапьно через отверстие в крышке 12 по.реэкому просветлению сло эмульсии между электродами.Saturn 1.5 V, Mars 1.5 V, Krona 9.0, etc. At small gaps between the electrodes (e.g., 100 microns), high electric field strengths occur in the order of 100-1000 V / cm with voltages on the electrodes of 1-10 V, respectively. At certain strengths of the electric field between the electrodes, a breakdown of the emulsion occurs and its destruction, which is observed visually through the hole in the lid 12, according to the clearing of the emulsion layer between the electrodes.
.. . Если в устройстве зазор между электродами составл ет 100 мк, то.. If in the device the gap between the electrodes is 100 microns, then
при использовании источника питани в 5 В создаётс напр женность электрического пол в 500 В/см. Следовательно , если исследуема в предлагаемом устройстве эмульси не разрушаетс при этих услови х, она стабильна и пригодна дл практического использовани , если разрушаетс - стабильность ее маЛа.using a 5 V power source creates an electric field strength of 500 V / cm. Therefore, if the emulsion tested in the proposed device is not destroyed under these conditions, it is stable and suitable for practical use, if it is destroyed, the stability of its small.
изобретени the invention
Устройство дл определени электростабильности эмульсионных буровых растворов, содержащее корпус с крышкой , измерительные электроды с токопроводами , соединенные с блоком питани и блок дл регистрации, отли чающеес тем, что, с цель упрощени процесса измерени и повышени степени электробезопасности, измерительные электроды установлены один над другим, образу чейку дл исследуемой жидкости, оДин из которых выполнен прозрачным, причем токопроводы установлены в корпусе с возможностью регулировани зазора между электродами.A device for determining the electrical stability of emulsion drilling fluids, comprising a housing with a lid, measuring electrodes with conductors connected to a power supply unit and a recording unit, which, in order to simplify the process of measuring and improving electrical safety, are installed one above the other, a cell for the test liquid, one of which is made transparent, and the conductors are installed in the housing with the possibility of adjusting the gap between the electrodes.
