System and method for monitoring make-up and running operations of well cementation and completion tools

Abstract

The invention discloses a system for monitoring make-up and running operations of well cementation and completion tools. The system comprises a make-up information collection module, a running tool information acquisition module and an information collecting and processing module, wherein the make-up information collection module is used for collecting make-up quality information of current well cementation and completion tools during make-up; the running tool information acquisition module is used for acquiring specifications of the current well cementation and completion tools and the designsequence of the tools in a preset well cementation and completion construction operation sequence; and the information collecting and processing module is used for obtaining the make-up quality information, the tool specifications and the design sequence information of the current tools, detecting whether the make-up effect of the current tools is qualified or not according to the make-up qualityinformation, detecting the accuracy of the current running tool according to the tool specifications and the design sequence information, and after the current well cementation and completion tools are all detected to be qualified, the current tools are conveyed to the underground. The system is easy to install and operate, human errors in the construction process are avoided, and the field workefficiency is improved.

Description

technical field [0001] The invention relates to the field of petroleum engineering, in particular to a system and method for monitoring the make-up and run-in operations of cementing and completion tools. Background technique [0002] At present, in the wellhead construction of cementing and completion, there are generally the following problems: first, whether the number and sequence of key tools (such as centralizers) to be lowered are strictly in accordance with the construction design plan, because this situation is difficult during the construction process. The lack of real-time monitoring and error prompts has caused human errors such as cementing and completion tools to be lowered incorrectly and leaked down, which affect the construction quality; Serious downhole accidents such as pipe string loosening; third, the process of running tools and making up pipe strings lacks real-time and effective supervision by Party A. [0003] The existing cementing and completion w...

[0002] At present, in the wellhead construction of cementing and completion, there are generally the following problems: first, whether the number and sequence of key tools (such as centralizers) to be lowered are strictly in accordance with the construction design plan, because this situation is difficult during the construction process. The lack of real-time monitoring and error prompts has caused human errors such as cementing and completion tools to be lowered incorrectly and leaked down, which affect the construction quality; Serious downhole accidents such as loose pipe strings; third, lack of real-time and effective supervision by Party A in the process of running tools and making up pipe strings

The disadvantage of this method is that the manual workload is large; the video surveillance cannot accurately control the construction details, and cannot find construction errors in a timely and effective manner and give an alarm; the construction process can only be inspected regularly, and the real-time monitoring of the whole process cannot be realized
