Specific implementation mode
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
In the description of the present invention, it is to be understood that, term "upper", "lower", "front", "rear", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is orientation based on ... shown in the drawings or position Relationship is set, is merely for convenience of description of the present invention and simplification of the description, device is not indicated or implied the indicated or element is necessary With specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
Please refer to Fig. 1 to Fig. 7, the logging while drilling apparatus mandrel 10 of an embodiment includes mandrel ontology 11, have into The metal flow passage pipe 12 and clamping element 13 of liquid mouth 121 and liquid outlet 122.Storage tank, metal flow passage are offered on mandrel ontology 11 Pipe 12 is arranged in storage tank, and inlet 121 and liquid outlet 122 are arranged at 11 outside of mandrel ontology, and clamping element 13 is distinguished It is connect with mandrel ontology 11 and metal flow passage pipe 12, clamping element 13 makes mandrel ontology 11 clamp metal flow passage pipe 12.
Specifically, metal flow passage pipe 12 uses high-strength corrosion-resistant compo pipe, if C276 (Hastelloy) is managed, Inconel718 compo pipes etc..The internal diameter of metal flow passage pipe 12 is by with turning the mud flow rate range of logger according to industrial standard Selected, the pipe outside diameter of metal flow passage pipe 12 is codetermined by internal diameter and with the bearing requirements for turning logger.Mandrel ontology 11 by Regular tenacity alloy, such as 300 series stainless steels are opened up storage tank and place metal in an axial direction as raw material on mandrel ontology 11 Flow-path tube 12.Other positions placement sensor on mandrel ontology 11, circuit board and its between connection, mandrel ontology 11 can Using molding structure is integrally machined, the assembly structure of multiple components, the present embodiment can also be used simultaneously to be not specifically limited.
In the present embodiment, logging while drilling apparatus mandrel 10 uses the split-type design of metal flow passage pipe 12 and mandrel ontology 11, Storage tank is opened up on mandrel ontology 11 in an axial direction, metal flow passage pipe 12 is arranged in storage tank, metal flow passage pipe 12 and mandrel sheet Radial clamping is carried out between body 11 by clamping element 13 to fix.When metal flow passage pipe 12 is assembled with mandrel ontology 11, by metal stream Deferent 12 is put by the opening of storage tank in storage tank, then is by metal flow passage pipe 12 and the clamping of mandrel ontology 11 with clamping element 13 Can, installation operation is simple and convenient.
Metal flow passage pipe is arranged in above-mentioned logging while drilling apparatus mandrel in mandrel ontology, can effectively avoid mud to mandrel sheet Body causes to corrode, and to reduce the material requirements to mandrel ontology, metal flow passage pipe can be used cheap metal tube and be made, can Substantially reduce the mandrel cost of connector for logging while drilling.Also, metal flow passage pipe is simple in structure, is easily easy by erosion corrosion position pre- It surveys, assesses that degradation degree is simple and practicable, it can be achieved that detection in time is replaced by thickness measure, the tool of thereby may be ensured that will not be because It excessively washes away and bearing capacity is caused to decline and fail, detection maintenance cost can be further decreased.Meanwhile even if during use Metal flow passage pipe is corroded by mud, directly removes the metal flow passage pipe that metal flow passage pipe more renews, without to mandrel ontology It is replaced, replacement operation is simple and convenient, of low cost, and helps to extend mandrel ontology service life, further saves into This.Therefore, compared with tradition is with the mandrel of logger is turned, above-mentioned logging while drilling apparatus mandrel is low with product cost, detection is tieed up Shield is convenient, maintenance cost is low and advantageous effect with long service life.
In one embodiment, it is provided with close to one end of inlet 121 and/or liquid outlet 122 on metal flow passage pipe 12 Bending segment 123.123 one side of bending segment can be near inlet 121 and/or liquid outlet 122 to entering metal flow passage pipe 12 Interior mud carries out water conservancy diversion, keeps mud flowing more smooth, helps to prevent runner from blocking;On the other hand, the bending of bending segment 123 Gap can be formed between place and mandrel ontology 11, can be used for that the electronic components such as sensor, circuit board and connection line are installed, Electronic component is facilitated to install.In the present embodiment, bending segment is set in one end of the inlet 121 close to metal flow passage pipe 12 123, and along mud flow direction, close to the overbending direction and close liquid outlet 122 1 of the bending segment 123 of 121 side of liquid outlet The overbending direction of the bending segment 123 at end is opposite.But in practical applications, the quantity of specific bending 123, overbending direction and curved Dog-ear degree etc. can be arbitrarily arranged according to actual needs, and the present embodiment is simultaneously not specifically limited.However, it is necessary to which explanation, is anti- Only mud excessively washes away, and the bending angle of bending segment 123 should not be too large, as shown in figure 3, in one embodiment, bending segment 123 Bending angle ɑ be less than or equal to 10 °.
