Managing operation of a sealing element is described. In some aspects, failure of the sealing element of a pressure drilling system may be predicted. Deformation of the sealing element as a tool joint is pulled through the sealing element may be detected and tracked to determine if a deformation pattern of sealing element changes. Responses of sealing element due to one or more of stress, strain, temperature, mechanical load, and pressure using a network of sensors around sealing element can be detected. Responses may be tracked over time. Detected responses are compared to tracked responses to identify changes in the symmetry of responses over time or changes in magnitude of responses over time. Changes are associated with fractures occurring within sealing element. A remaining life of sealing element is predicted based on the changes and replacement may be scheduled based at least in part on the predicted remaining life.

The invention discloses a controlled ultra-short radius guiding well drilling system and method, and relates to the technical field of well drilling, the system comprises a drilling machine, a conventional drill rod, a flexible drill rod structure, a data relay transmission short section structure, a flexible motor structure, a measurement-while-drilling short section structure and a drill bit which are connected in sequence; the measurement-while-drilling short section structure is used for measuring well deviation and azimuth information; the data relay transmission short section structure is used for receiving well deviation and azimuth information measured by the measurement-while-drilling short section structure and sending the well deviation and azimuth information to a drilling machine; the flexible drill rod structure comprises at least one flexible drill rod short section, and the flexible motor structure comprises at least one flexible motor. The well drilling method can be used for directional well drilling and composite well drilling. According to the method, the purposes of well track control and drilling speed increasing and efficiency increasing of the ultra-short radius directional well are achieved.

The invention relates to the technical field of machining of photovoltaic backboard glass, in particular to an online series type drilling system for photovoltaic module backboard glass. The online series type drilling system comprises a transfer assembly line used for transferring the backboard glass, automatic positioning devices located above the transfer assembly line, and drilling machines located on one side of the transfer assembly line. The transfer assembly line stops the backboard glass on one sides of the drilling machines according to a control signal, the automatic positioning devices move downwards and fasten the backboard glass, and the backboard glass is drilled through the corresponding drilling machine. By means of the online series type drilling system for the photovoltaic module backboard glass, online drilling of the photovoltaic backboard glass is achieved, and meanwhile the requirement for the production capacity of 3-15 pieces per minute is met. In addition, one side of the transfer assembly line is provided with at least four sets of drilling machines, at least one set of drilling machine serves as a standby machine, abnormal conditions can be detected, the broken drilling machine is replaced by the standby machine, and in this way, the first-pass yield of products can be increased to be over 98%.
