Abstract
The utility model discloses a combined mounting bracket for drilling fluid outlet sensors. The combined mounting bracket comprises a rectangular frame, wherein fixing clamps are oppositely arranged on the upper and lower opposite sides of one lateral surface of the rectangular frame; the opposite upper and lower fixing clamps form sensor fixing fulcrums; fixing structures for fixing the rectangular frame are arranged on the rectangular frame. According to the combined mounting bracket, the situation that measurement errors are increased by the mounting of the outlet sensors is changed, the outlet sensors are more normatively arranged, and the purchasing cost is greatly lowered.
Description
Technical field
The utility model relates to a kind of drilling fluid outlet sensor combinations mounting bracket, for comprehensive logging instrument sensor, in the installation in drilling fluid exit, fixes, and belongs to the design and manufacturing technology field of comprehensive logging instrument installation of sensors fastening devices.
Background technology
According to the needs of drilling well and well logging, surge tank packing density sensor, temperature pick up and conductivity sensor in drilling fluid exit, lead parameter to gather the required density in exit, temperature and electricity.
At present, in drilling process, from well, drilling fluid out of circulation first flows in surge tank by pipeline, then in surge tank packing density sensor, temperature pick up and conductivity sensor.The installation of each sensor is fixed and is adopted a mounting frame for sensor, and D Xing Ka， one end is fixed on surge tank mural margin, and the other end is fixed a sensor; Adopt this mode, with 3 D type cards, fix density sensor, temperature pick up and the conductivity sensor of outlet.
Existing drilling fluid outlet installation of sensors mode, there is following drawback: one, cause sensor measurement error to increase: owing to adopting D type card to fix conductivity sensor, make conductivity sensor be less than 12cm(conductivity sensor mounting technique index request from the distance of metal buffer tank inwall and be greater than 12cm from metal distance), cause conductivity sensor measure error to increase; Density sensor adopts D type card to fix, and for single fulcrum, fixes, and adds the stirring of degasser in surge tank and the power such as inflow of drilling fluid, easily causes sensor perturbations, even swings, will be larger on the impact of density sensor accuracy of measurement.Two, install lack of standardization: in surge tank packing density, electricity lead, temperature pick up, degasser, drilling fluid pipeline etc., add that surge tank volume is little, every well logging team mounting means is different, have concentrated, unification lack of standardization; In addition, looking up the fault is more difficult.These drawbacks all have direct relation with used mounting frame for sensor (D type card).
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing drilling fluid outlet mounting frame for sensor exists, and a kind of drilling fluid outlet sensor combinations mounting bracket is provided.The installation that the utility model makes drilling fluid outlet sensor is standard, more stable more, does not affect the measure error of sensor, also can significantly reduce mounting bracket purchase cost.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of drilling fluid outlet sensor combinations mounting bracket, it is characterized in that: comprise rectangular frame, one side of described rectangular frame is provided with fixed card on the relative limit of Liang Tiao up and down, described fixed card is oppositely arranged, two fixed cards up and down that are oppositely arranged form the fixed support of sensors, and on described rectangular frame, are provided with for the fixing fixed structure of rectangular frame.
Fixed card on described top is one or more, and the fixed card correspondence on is below set to one or more, when a plurality of, and the upper and lower corresponding fixed supports that form many group sensors.
Described fixed structure comprises and is fixedly installed on the support fixed end of rectangular frame on below and is movably arranged on the support-moving fixed end of rectangular frame on below.
Described fixed card is M type fixed card, and the protuberance at M type fixed card middle part forms fixed support.
On the bottom and upper segment of described rectangular frame, be provided with horizontal connecting hole, fixed card is connected on the bottom and upper segment of rectangular frame by fixed screw and horizontal connecting hole.
Described rectangular frame is connected to form by four Hollow cuboids.
Employing the utility model has the advantage of:
One, the utility model has changed the situation that causes its measure error to increase because of outlet installation of sensors: on the one hand, conductivity sensor is fixed on to centre of the present utility model, conductivity sensor is greater than 12cm from the distance of metal buffer tank inwall, the present situation of having avoided conductivity sensor to cause measure error to increase from metal close to too; On the other hand, adopt fixing every the sensor of two fulcrums, more firm, can fixation of sensor vertical, do not tilt, particularly density sensor, and placed the utility model away from one end of degasser, thereby reduced density sensor, measure influence factor accurately.
Two, installation of sensors standard more: utilize the utility model, can ensure that the outlet installation of sensors of Mei Zhi troop is uniform, more standard; Also more convenient for installation of sensors, dismounting and fault diagnosis.
Three, significantly reduce purchase cost: existing Installation Modes, need 3 D type cards, each 340 yuan, 1000 yuan of left and right of 3 needs, adopt the utility model, only need one, and price is less than 200 yuan, and purchase cost reduces by 80%; If increase sensor in drilling fluid exit, needs of every increase are purchased a D type card, just increase a mounting bracket buying expenses, adopt the utility model that 5 sensors can be installed simultaneously, even more, but do not increase expense.
