Description
ровани взаимодействуют с полуцилиндрами 1 и 2. В результате в них вознп1;:ут пр жени , величина которых зависит от соотношени модулей упругости поролы п:.к-.териала полуцилиндров и поэтому будет различной в том и другом полуцилиндрах. Соответственно напр жени м в полуцилиндрах 1 и 2 возникнут напр жени в приклеенных к их торцам фотоупругих покрыти х 3 и 4. Наблюда оптическую картину в каждом из фотоупругих покрытий и сравнива их между собой и с тарировочными образцами, суд т о величине модул упругости иороды.They interact with semi-cylinders 1 and 2. As a result, voznp1;: yarns, the value of which depends on the ratio of the elastic moduli of the foam n: n-semi-cylinders and therefore will be different in the two semi-cylinders. Accordingly, the stresses in the semicylinders 1 and 2 will cause stresses in the photoelastic coatings 3 and 4 glued to their ends. Observing the optical picture in each of the photoelastic coatings and comparing them with each other and with calibration samples, the magnitude of the elastic modulus of the orbit is judged.
Датчик следует ориентировать в скважине так, чтобы илоскость соприкосновени полуцилиндров совпадала с направлением одного из главных напр жений в породе. В этом случае значительно упрощаетс процесс тарировани датчиков.The sensor should be oriented in the well so that the contact between the semicylinders coincides with the direction of one of the main stresses in the rock. In this case, the process of calibrating the sensors is greatly simplified.
