Problems solved by technology

[0002] In the construction process of geological drilling, oil drilling and oil production operations, it is necessary to run the drill pipe or tubing string into the downhole. When running the string, it is necessary to measure the length of each string arranged on the site with a ruler, record them one by one, and go down the well Connect the pipe strings in order, and after running into the well, it is necessary to accumulate the length of each pipe string to determine the depth of the pipe string and the downhole tool. For many years, it has been manually measured and accumulated. Due to the bending of the measuring tape, the measurement position is not standard. The error of the measurement value of each pipe string is very clear. The accumulation of the errors of hundreds of pipe strings will cause an error of about several meters. Due to the limitation of the measurement means, the measurement accuracy is low. Subsequent drilling and oil production operations have caused negative impacts, and even caused downhole operation accidents

specific Embodiment approach

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, this kind of automatic measurement system for oil pipe string operation, such as figure 1 As shown, it consists of a rotating laser 1, a pulley 2, a photosensitive scale detector 3, a suspension weight sensor 4, power and signal cables 5, and a reading display 6.

[0013] The suspension load sensor 4 is a standard working machine component, and the system uses a wire connection to collect its parameters.

[0014] The rotating laser 1 may be replaced by a straight-line laser. The straight-line laser gathers a beam of laser light into a straight-line segment through a lens. parallel.

[0015] figure 1 The traveling block A, elevator B, and tubing string C are standard operating machine equipment. The operating machine used in the operating machine is a drilling ...

Abstract

The invention relates to an automatic measurement system for oil pipe string operation, which is composed of a rotating laser, a pulley, a photosensitive scale detector, a suspension weight sensor, electric power and signal cables, and a reading display instrument, which solves the troublesome oil pipe string operation The problem of string length measurement for many years has overcome the disadvantages of manual measurement, low precision, cumbersome and error-prone, the instrument is easy to install and use, with less manual intervention during use and a high degree of automation. Accurate string length measurement is the follow-up Drilling and oil production operations provide technical quality assurance.

Description

Technical field: [0001] The invention relates to the field of petroleum downhole operation instruments and equipment, in particular to a system for automatically measuring the cumulative length of a petroleum pipe string operation. Background technique: [0002] In the construction process of geological drilling, oil drilling and oil production operations, it is necessary to run the drill pipe or tubing string into the downhole. When running the string, it is necessary to measure the length of each string arranged on the site with a ruler, record them one by one, and go down the well Connect the pipe strings in order, and after running into the well, it is necessary to accumulate the length of each pipe string to determine the depth of the pipe string and the downhole tool. For many years, it has been manually measured and accumulated. Due to the bending of the measuring tape, the measurement position is not standard. The error of the measurement value of each pipe string is...
