Because the utility model adopts a method of uniformly distributing mounting holes on the sensor array bearing fix outer case and arranging the supersonic semi-diameter measuring transducer on the mounting hole, and non-contact type measuring; the measuring error is small and it can measure up and down at will. The eccentric center and borehole deviation has no influence on the instrument, and it is convenient to repair and simple to use. Besides, the utility model has the advantages of reasonable design and simple structure, therefore, it is suitable to be popularized and applied on site.
Description
Technical field
This practicality newly relates to the downhole measurement tools of using on a kind of oilfield, particularly a kind of ultrasonic wave caliper logging instrument.
Technical background
The caliper logging instrument is a kind of downhole instrument that is used in drilling well and the measurement of manufacturing process borehole diameter real-time continuous, the measuring instrument that generally uses on the oil field adopts the mechanical type instrument at present, in the lower going-into-well, after blowing, stretch out four feeler arms and measure four well radiuses of same depth point, thereby measure the well hole diameter of an average diameter.The error of its caliper logging is big, does not react the well bore real structure, and in the continuous measurement process, can only go up survey and can not descend to survey.
Technical scheme
The purpose of this utility model is to provide a kind of ultrasonic wave caliper logging instrument, it adopts the non-contact ultrasonic measuring method, a plurality of well radiuses on the plane, same depth point under the measuring well with the value of these radius measurements, can be formed the 3 D stereo hole diameter block diagram of a plurality of diameters simultaneously.Measure accurately, and can go up survey, survey continuous measurement down.
The purpose of this utility model is to realize like this, it by on be tightly connected the head (1), sensor array pressure-bearing fixed housing (2), temperature pick up (3), liquid acoustic velocity ultrasonic sensor (4), reflector (5), adjust screw (6), ultrasonic wave radius measurement sensor (7), installing hole (8), well aspect sensor (9), excitation control circuit (10), received signal treatment circuit (11), sealing ring (12), lower seal joint (13), helmet (14) is formed, helmet (14) successively with on be tightly connected the head (1), sensor array pressure-bearing fixed housing (2), sensor of direction of deflection (9), excitation control circuit (10), received signal treatment circuit (11), lower seal joint (13), helmet (14) connects, on sensor array pressure-bearing fixed housing (2), a window is arranged, temperature pick up (3) is housed in it, liquid acoustic velocity ultrasonic sensor (4), reflector (5), adjust screw (6), at sensor array pressure-bearing fixed housing (2) equally distributed installing hole (8) is arranged, ultrasonic wave radius measurement sensor (7) is housed, with sealing ring (12) on installing hole (8), sealing.
During work, underground ultrasonic ripple excitation control circuit excites each ultrasonic wave in certain sequence successively, ultrasonic wave radius measurement sensor receives the back wave that the own borehole wall of launching returns in the gate-width of regulation in the time, according to the detected Mintrop wave time, after the received signal processing circuit processes of down-hole, deliver to ground-based computer by logging cable and handle, print borehole diameter, radius data curve or 3 D stereo block diagram.
The utility model has equally distributed installing hole owing to having adopted at sensor array pressure-bearing fixed housing, and ultrasonic wave radius measurement sensor is housed on installing hole, and contactless nothing machinery is measured, so measure error is little, can arbitrarily go up survey, the following survey.And be not subjected to the influence of the eccentric and hole deviation of instrument, easy to maintenance, use simply, the utility model is reasonable in design, simple in structure, is well suited for field popularization application.
