Abstract
The utility model relates to an integrated grooving coil system, which comprises a glass fiber reinforced plastic mandrel. The integrated grooving coil system is characterized in that the surface of the glass fiber reinforced plastic mandrel is equipped with the coil system, and the coil system is equipped with an annular notch groove. The integrated grooving coil system has the advantages that the coil system grooved and processed by the mandrel which is stable and reliable and is low in variation is low in mechanical variation under a high-temperature and high-pressure environment, increasesinstrument stability and reliability, and is convenient for dismounting and maintenance simultaneously.
Description
Affiliated technical field
The utility model relates to the oil well logging instrument coil system of induction logging of a kind of high temperature high voltage resistant, good insulating, especially is fit to a kind of integrated cutting coil system of no magnetic signal.
Background technology
At present, both at home and abroad coil system of induction logging mainly adopts split type coil system pattern, because that coil system of induction logging requires is nonmetal, do not have magnetic and require under the High Temperature High Pressure variable quantity little, therefore adopts glass-reinforced plastic material.And very high to the accurate to dimension requirement, have only the split type processing of employing could guarantee its machining precision, but fixing unstable between split type coil system dismounting inconvenience and each split, coil system size and position change easily.On basis, integrated cutting inductive coil series is proposed to glass-reinforced plastic material test of many times and calculating.
Summary of the invention
In order to overcome the problem that the induction logging instrument coil system changes under High Temperature High Pressure, the utility model provides a kind of integrated cutting coil system, and this coil system is not only little at high temperature (175 ℃) and the following variable quantity of high pressure (140MPa), and loading and unloading and easy to maintenance.Stability and the reliability that increases instrument there is very big effect.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of integrated cutting coil system, it comprises fiber reinforced plastics rod, it is characterized in that: the surface at fiber reinforced plastics rod is provided with coil system, in coil system the ring-type cutting is set.
1) glass-reinforced plastic material that does not adopt glass cloth to suppress adopts composite glass fiber reinforced leading-drawing rod; 2) Straight pull is adopted in the processing of fiber reinforced plastics rod, the time processing moulding, the axial high temperature stroke of such processing mode is little, stable and reliable for performance; 3) multiple metering method is adopted in the processing cutting, from central point and the calculating of edge point etc.4) speciality tool is adopted in cutting processing, guarantees the concentricity of all cuttings and the homogeneity of cutting spacing.
The beneficial effects of the utility model are, the coil system that cutting processes on the little plug of a kind of reliable and stable variable quantity, and mechanical variable quantity is little under high temperature and high pressure environment, increases the stability and the reliability of instrument, is convenient to dismounting and maintenance simultaneously.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a synoptic diagram of the present utility model.
Shown in the figure, 1 is that cutting, 2 is that coil system, 3 is the surface of fiber reinforced plastics rod for fiber reinforced plastics rod, 4.
Embodiment
