Description
Technical field
The utility model relates to oil pipe depth correction instrument technical field.
Background technology
In the existing sleeve pipe depth correction instrument device of oil field, be mainly well logging depth correction instrument device, be lowered to cable, record collar position by electronic instrument, thereby be not suitable in continuous oil pipe operation.
Utility model content
The utility model object is to provide a kind of simplicity of design, easy and simple to handle, and reliability is strong, the coiled tubing depth correction instrument of accurate positioning.
The utility model comprises landing nipple, periphery middle part at described landing nipple is provided with several axial notches, at described axial notch, place arranges locating piece, and the upper end of described locating piece is limited between axial notch and spacing ring by spacing ring, and described spacing ring is fixedly connected with landing nipple; The lower end of described locating piece is positioned between axial notch and locating ring by locating ring, and described locating ring rotary type is nested with on landing nipple; Sheet spring is set in the axial notch between described locating piece and landing nipple; On the perisporium of described locating ring, be provided with stop screw hole, stop screw is threaded on landing nipple.
The utility model in use, connect depth correction instrument and related tool string, with coiled tubing (or oil pipe) by tool string uniform speed slow lower going-into-well, with reference to well logging related data, carry oil pipe in short sleeve position on slowly, and the load variations of observing weight indicator, in the time that the locating piece in depth correction instrument is crossed the gap between casing coupling, locating piece is by hanging sleeve end surfaces, weight indicator increases the load that has 20 kN left and right, repeatedly put on herein and put several times, confirm after the short sleeve degree of depth, adjustment tubing length and tubing depth error, determine collar position by the method again.The utility model is for collar location, and the error of check and correction connecting leg length and casing length, prevents that packer is sitting on collar, prevents hydraulic perforating degree of depth mistake.The utility model simplicity of design, simple to operate, reliability is strong, accurate positioning, accurately locating sleeve box cupling position, makes packer avoid casing coupling, can be used for the constructions such as selective acidizing, abrasive perforating and staged fracturing.
The utility model arranges a rectangular recess of being convenient to install locating piece in described locating ring upper end.The utility model locating ring can rotate in the low groove of landing nipple, when locating piece is installed, rectangular recess rotation, to aliging with the axial notch of landing nipple, is put into locating piece and sheet spring depressed, and rotation locating ring, is stuck in locating piece in locating ring; After installing, the screw hole rotation on locating ring is extremely alignd with the screw hole on landing nipple, then dog screw is screwed on landing nipple.
