Abstract
The utility model relates to a micro spherical density integration logging focused tool of oil exploration geophysical logging which solves the problems that the logging time is long and the construction difficulty is high. The utility model is characterized in that: a density detector probe (3) and a micro spherical plate probe (2) are separately connected with a body (4) symmetrically by two bracing arms (5), wherein two ends of the two bracing arms (5) are rotatable. The utility model has the advantages of two instruments measuring down hole simultaneously, so that the cost is saved; the logging time is reduced; and the efficiency is increased.
Description
The utility model relates to the used instrument of petroleum prospecting geophysical well logging, belongs to the integrated well logging telescoping ram of microballoon density.
Microballoon instrument and density instrument all are oil well logging instruments, and in the well logging construction, the microballoon instrument is used for measuring the stratum flushed zone resistivity; And density instrument is used for measuring formation porosity and judge lithology, with other well-log informations the stratum is estimated afterwards, determines the oil gas water and the oil saturation on stratum, for oil exploitation provides interpretation data., in reality well logging construction, obtain the well-log information of stratum flushed zone resistivity and formation porosity and oil saturation, microballoon instrument and density instrument should be gone into the well respectively, increase the time of well logging and the difficulty of well logging construction.
The purpose of this utility model is to avoid the weak point that exists in the above-mentioned present technology, and the integrated well logging telescoping ram of the microballoon density that provides a kind of instrument to go into the well simultaneously.
The purpose of this utility model can reach by the following technical programs: the integrated well logging telescoping ram of this microballoon density, form by main body, microballoon pole plate probe and density detector probe, it is characterized in that: density detector probe and microballoon pole plate probe are connected on the main body by equidistant two sway brace symmetries respectively, and wherein the sway brace two ends all are rotating.
The utility model has following advantage than above-mentioned prior art: because density detector probe and microballoon pole plate probe are connected on the main body by equidistant two sway brace symmetries respectively, make two kinds of logging instrumentation probes be integrated together, with main body difference parallelogram structure, when opening and drawing in this instrument, two kinds of instrument probe are stressed evenly, can contact with the borehole wall well, measurement data is accurate.Reduced by a telescoping ram simultaneously, saved very big cost, reduced the number of times of going into the well, shortened the time of well logging.
Accompanying drawing 1 is a structure cut-away view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the integrated well logging telescoping ram of this microballoon density is made up of main body 4, microballoon pole plate probe 2 and density detector probe 3, and density detector probe 3 and microballoon pole plate 2 probes do not change with original instrument, just be connected on the main body 4 by two identical sway brace 5 symmetries of length respectively, wherein no matter sway brace 5 two ends are to connect instrument probe (2,3) it all is rotating still connecting main body 4, makes pole plate probe 2 and density detector probe 3 and main body 4 form parallelogram sturcutre.So in use, give this instrument power supply, revolution is passed to telescoping ram running part 1 with power, makes it to drive sway brace 5 and opens and draw that (during well logging, sway brace 5 opens in; After having surveyed, sway brace 5 draws in), and then the probe of two kinds of instruments (2,3) is stressed evenly, probe (2,3) can contact with the borehole wall well, and measurement data is accurate.Reduced by a telescoping ram simultaneously, saved very big cost, reduced the number of times of going into the well, shortened the time of well logging.
Claims (1)
