Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of oil-scraping device of eccentric borehole logging tool cable, comprises pressure cap 1, packing 2, packing Glan 3, base for supporting 4.Wherein, pressure cap 1 is provided with the first inlet wire groove 101 vertically; Packing 2 center is provided with the second inlet wire groove 201, and the angle between the centerline direction of this second inlet wire groove 201 and vertical direction is 30 °-60 °; Base for supporting 4 is provided with the 3rd inlet wire groove 401 vertically.
Pressure cap 1, packing 2, base for supporting 4 connect from top to bottom in turn, and the first inlet wire groove 101, second inlet wire groove 201 forms with the 3rd inlet wire groove 401 inner chamber be connected jointly.
Packing Glan 3 is separately positioned on the top and bottom of packing 2, and respectively with the lower end of pressure cap 1 and the upper end close contact of base for supporting 4.
The oil-scraping device that the utility model embodiment provides, for removing the sump oil of well logging cable surface in eccentric borehole logging tool process.In application process, after logging equipment is gone into the well, the oil-scraping device that the utility model embodiment provides is connected on test port that eccentric well large flange covers, and makes well logging cable from bottom to top in turn through the 3rd inlet wire groove 401, second inlet wire groove 201 and the first inlet wire groove 101 of this oil-scraping device.Because the second inlet wire groove 201 in packing 2 is obliquely installed, the angle between its centerline direction and vertical direction is 30 °-60 °, therefore, well logging cable is carried in process, and the sump oil of its surface adhesion will be scraped by packing 2 and fall after rise in testing well.Visible, the sump oil of well logging cable surface can all scrape in testing well by the oil-scraping device that the utility model embodiment provides, time saving and energy saving and avoid well logging cable and sump oil is carried into the problem of environmental pollution caused outside well.
Particularly, as shown in Figure 1, base for supporting 4 comprises the pressure cap junction 402, packing supporting section 403 and the test port junction 404 that connect successively from top to bottom.It is inner that pressure cap 1 is positioned at pressure cap junction 402, and contact with the inner wall sealing of pressure cap junction 402.The utility model embodiment is by as above arranging base for supporting 4, to realize with upper end and pressure cap 1 close contact, its middle-end coordinates pressure cap 1 and packing Glan 3 to compress packing 2, the test port compact siro spinning technology of its lower end and logging equipment, so that make the sump oil that well logging cable scrapes fall in testing well.
Further, penetrate in the first inlet wire groove 101, second inlet wire groove 201 and the 3rd inlet wire groove 401 for the ease of well logging cable, between base for supporting 4 and pressure cap 1, and preferably removably connect between base for supporting 4 and the test port of testing well, such as, be threaded.For example, the first internal thread can be provided with on the inwall of pressure cap junction 402, correspondingly, the outer wall of pressure cap 1 arrange the first external screw thread matched with this first internal thread.The second external screw thread can be provided with on the outer wall of test port junction 404, correspondingly, the inwall of the test port of testing well arrange the second internal thread matched with the second external screw thread.
As preferably, the angle in packing 2 between the centerline direction of the second inlet wire groove 201 and vertical direction is 45 °.Setting like this, can make the contact area between the well logging cable sidewall relative with the second inlet wire groove 201 be consistent, thus ensures that sump oil on the well logging cable in the second inlet wire groove 201 is by evenly and fully scrape in testing well.
Further, in the utility model embodiment, the groove width of the first inlet wire groove 101, second inlet wire groove 201 and the 3rd inlet wire groove 401 can adjust according to the difference of the diameter of used well logging cable, and the groove width of this three is preferably equal, such as, be 6-10mm.Particularly, according to the diameter of the well logging cable that this area is commonly used, the groove width of the utility model embodiment preferably the first inlet wire groove 101, second inlet wire groove 201 and the 3rd inlet wire groove 401 is 8mm.Wherein, it will be understood by those skilled in the art that, above-mentioned groove width can be understood as the diameter (when each inlet wire groove is manhole) of groove, also can be understood as the distance (when each inlet wire groove is cuboid or square bodily form through hole) between the left side of each inlet wire groove and right side.
Further, the packing 2 preferably rubber packing that the utility model embodiment is used, to ensure durability and the sealing of packing 2.
Further, as shown in Figure 1, the oil-scraping device that the utility model embodiment provides also comprises chuck 5, and this chuck 5 is arranged on the below of base for supporting 4, on the outer wall of preferred packing supporting section 403.As preferably, this chuck 5 can be hex nut structure.By as above arranging chuck 5, so that use this oil-scraping device of tool into rotation such as spanner, make it be in position that handled easily personnel carry out frizing construction.
Based on above-mentioned, the utility model embodiment can adopt following preferred method to strike off the sump oil on well logging cable: after entering testing well under logging instruments, by the well logging cable of tester, penetrate the 3rd inlet wire groove 401 on base for supporting 4, then the test port that the test port junction 404 of base for supporting 4 and eccentric well large flange cover is threaded connection.By using spanner to rotate chuck 5, making base for supporting 4 towards operating personnel, then well logging cable is penetrated in the second inlet wire groove 201 of packing 2, and packing 2 is pressed on packing Glan 3, well logging cable being clamped in effectively the axle center place of this oil-scraping device.Finally well logging cable is penetrated in the first inlet wire groove 101 of pressure cap 1, then pressure cap 1 is threaded with the pressure cap junction 402 of base for supporting 4, packing 2 is pressed between packing Glan 3 under the acting in conjunction of pressure cap 1, packing Glan 3 and base for supporting 4.So, well logging cable has been carried in process, the sump oil that its surface is carried all will be struck off by packing 2 and fall after rise to testing well inner, thus reaches the object of well logging cable being carried out to frizing in well logging.
The foregoing is only preferred embodiment of the present utility model; not in order to limit protection domain of the present utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
