作为油田开发、油气储层改造的重要技术,连续管测井、射孔和压裂酸化等工艺作业需求激增,且必须通过井下数据采集传输及控制信号完成井下测试及控制作业,但目前国内外主要采用的特制电缆连续管滚筒装置及测井滚筒作业机,存在功能单一、成本高且结构复杂和通用差等问题。因此,基于常规连续管作业机结构特点、通过对现有连续管测试及控制数据信号传输系统分析,完成多适应性连续管测控系统配套信号传输装置研究设计,研究并设计一类通用性强且传输高效的多适应性连续管信号测试、采集传输及反馈控制系统配套信号传输装置,省去传统设备定制化加工制造及作业工艺适应性单一导致的高成本、繁杂结构导致的作业及检修操作的高劳动强度,对于实现连续管作业机智能测控一体化多功能转型升级意义重大,同时对于未来油田开发的数字化网络实时监测系统创新极为重要。

As an important technology for oilfield development and oil and gas reservoir transformation,the demand for coiled tubing logging,perforation and fracturing acidizing increases sharply,and downhole testing and control operations must be completed through downhole data acquisition,transmission and control signals.At present,however,the special cable coiled tubing drum device and logging drum machine used mainly at home and abroad have some problems,such as single function,high cost,complex structure,poor general purpose and so on.Therefore,based on the structural characteristics of conventional coiled tubing operation machine,through the analysis of existing coiled tubing testing and control data signal transmission system,the research and design of signal transmission device for multi-adaptive coiled tubing measurement and control system is completed.A kind of signal transmission device for multi-adaptive coiled tubing signal testing,acquisition and transmission and feedback control system with strong versatility and high transmission efficiency is studied and designed,which saves the high cost caused by the customized manufacturing of traditional equipment and the high labor intensity of operation and maintenance operation caused by complicated structure.It is of great significance for realizing the transformation and upgrading of the multi-function of intelligent measurement and control integration of coiled tubing machine,and is extremely important for the innovation of the digital network real-time monitoring system for future oilfield development.
