China is a large country with abundant oil and gas reserves, and has a large number of oil and gas fields and oil and gas production enterprises. During the exploration and development of oil and gas fields, logging needs to be carried out after drilling so as to know the oil and gas containing condition of the stratum.
Conventionally, the logging information is obtained by putting an instrument into a well by a cable for measurement, however, in some cases, such as a highly deviated well with a well inclination exceeding 65 degrees or a horizontal well, the instrument is difficult to put down by using the cable, and in addition, the well wall is difficult to collapse or block, and the logging information is difficult to obtain. Drilling fluid circulation is needed in the drilling process, drilling debris can be brought out, the situation that drilling fluid filtrate invades the stratum can also occur, and great errors can exist in the obtained data. At present, people put a logging instrument on a drill bit to enable the drill bit to obtain various information of a stratum, namely logging while drilling, so that the logging can be carried out on wells in any condition, and the track of the drill bit can be timely adjusted by utilizing the measured drilling parameters and stratum parameters to enable the wells to drill along the direction of a target layer; and the formation parameters obtained by logging while drilling are the formation parameters just drilled, are closest to the original state of the formation, and are more favorable for evaluating the oil and gas content of the complex formation than the common cable logging.
One of the working modes of the logging-while-drilling system is a downhole data storage mode: the method has the advantages that all information collected when the logging-while-drilling instrument is tripped out of the drill or drills is stored in a memory of the underground instrument, and the information can be transmitted into an earth surface computer for processing and displaying through a data downloading line when the logging-while-drilling instrument is tripped out of the drill or drills into the ground.
