摘要/Abstract

摘要： 针对钻井岩屑样本取样智能化的迫切需求,瞄准提升岩屑代表性、样本获取及时性、运行可靠性,以及井场适应性等综合目标,研制了基于抽吸原理的岩屑自动取样系统,采用抽吸式取样技术和防混叠、固相/液相快速分离技术解决了常规取样方案由于岩屑混叠导致地层代表性差的问题。通过地层岩屑返出模型分析,应用机电一体化技术、RFID井深归位技术和岩屑取样自适应控制算法,实现系统小型化和适应性设计,解决了钻井现场复杂多变环境下的适应性难题。通过多口井的现场应用,充分验证了系统的岩屑取样代表性、可靠性、适应性和易用性,为录井朝着一体化、智能化方向发展奠定了基础。

Abstract: Aiming at the urgent demand for the automation of geological sample sampling in the mud logging industry, we are committed to improving the representativeness of cuttings, timeliness of sample acquisition, operational reliability, well adaptability. A cuttings automatic sampling system based on suction principle is proposed. The suction sampling technology, anti-aliasing and fast solid-liquid phase separation technology, are used to solve the problem of poor formation representation due to cuttings mixing in the conventional sampling scheme. Through the analysis of the formation cuttings return model, the electromechanical integration technology, RFID well depth homing technology and cuttings sampling adaptive control algorithm are applied to realize the miniaturization and adaptive design of the system and solve the complex and changeable environmental adaptability problem of the drilling site. Through the application of this system in multiple wells, the representativeness, reliability, adaptability and ease of use of the system's cuttings have been fully verified. This system has laid a foundation for the development of mud logging towards integration and intelligence.

Key words: suction type, cuttings, automatic sampling, solid-liquid separation, wireless communication, RFID
