Description
Technical field:
The present invention relates to a kind of array of sensor coils structure inductive probe, this array of sensor coils structure inductive probe is a kind of inductive probe that is used for the array induction oil well logging instrument.
Background technology:
The down-hole part of array induction logging tool is made up of three parts such as electronics pipe nipple, coil array and emission pipe nipples, and coil array is the key components of array induction instrument, and coils array construction is the key point of coil array.
Traditional induction logging is to utilize a plurality of transmitting coils, a plurality of receiving coil to connect respectively, generation has the fixedly coil array characteristic of investigation depth and longitudinal frame, but demand along with the oil field user, must design a kind of novel induction logging instrument (being array induction logging instrument), realize array and digitized measurement by its coil array array of sensor coils structure, obtain the detective curve of multiple longitudinal frame, multiple radial depth of investigetion.Thereby this instrument is had than more accurate, the more intuitive explanation results of conventional resistivity instrument, has the non-homogeneity ability in stronger division thin layer and the reflection layer, can intuitively reasonably describe stratum invasion character and true formation resistivity, become the important means that solves complicated heterogeneous reservoir well log interpretation.
Through investigation and retrieval, also do not find similar with the present invention or identical array of sensor coils structure at home.
Summary of the invention:
The objective of the invention is to design a kind of array induction coils array construction inductive probe that can realize array and digitized measurement, obtain the detective curve of multiple longitudinal frame, multiple radial depth of investigetion, thereby induction logging instrument is had than more accurate, the more intuitive explanation results of conventional resistivity instrument, has the non-homogeneity ability in stronger division thin layer and the reflection layer, can intuitively reasonably describe stratum invasion character and true formation resistivity, become the important means that solves complicated heterogeneous reservoir well log interpretation.
A kind of array of sensor coils structure inductive probe of the present invention is made up of metal mandrel, compound copper pipe, coil rack, spacing adjustment means; Metal mandrel is a hollow structure, and the through wires hole that metal mandrel runs through inside and outside being provided with perpendicular to the relative barred body wall of axis, metal mandrel barred body cylindrical wall are provided with the coil rack crossed beam trunking and cross oil groove; Compound copper pipe is enclosed within outside the metal mandrel, and compound copper pipe cylindrical wall is provided with the coil rack sliding tray; Coil rack is provided with through wires hole and winding slot, coil is wrapped on the winding slot, coil rack is according to arrayed, be installed on the coil rack sliding tray of compound copper pipe, coil rack is made up of a transmitting coil and eight group of received coils, and each receiving coil group is made up of a main receiving coil and an auxiliary reception coil; The spacing adjustment means is installed between the coil rack.
Metal mandrel is made by no magnetic metal material, and its endoporus hollow has crossed beam trunking on the cylindrical, solves to run through line and the outer practical problem of crossing phase mutual interference between the line of coil rack.
Compound copper pipe is made by twining non-metal insulating material on the copper body, effectively solves the interference that coil is crossed Line To Line ring framework winding.The array coil sliding tray is arranged on the cylindrical, and array coil sliding tray according to a determining deviation upper edge and is moved, and can realize the coil rack debugging of accurately sliding.
Coil rack and spacing adjustment means are made by ceramic materials, have low temperature change, low-gravity, high accuracy, high-intensity performance, guarantee the stability of coil array probe performance.
Advantage of the present invention and good effect:
1, the coils array construction among the present invention has realized array and digitized measurement in the process of well logging, can obtain the detective curve of multiple longitudinal frame, multiple radial depth of investigetion.
2, the metal mandrel special construction effectively solves and runs through line and the outer practical problem of crossing phase mutual interference between the line of coil rack in the instrument.
3, compound copper pipe has good shield effectiveness, effectively solves the interference that coil is crossed Line To Line ring framework winding, realizes the coil rack convenient debugging of sliding thereon simultaneously
4, the spacing adjustment means can make things convenient for, regulate accurately the spacing between the array coil.
