Embodiment Construction

[0023] As shown in the figure, screens 2 of different meshes such as 60 mesh, 80 mesh, 120 mesh, and 180 mesh are respectively installed in the housing 1 of the multi-layer particle size separation screen. Only three layers are shown in the figure, but the implementation may not be limited to three floors.

[0024] The virtual signal analysis processor 11 based on computer software and hardware technology is directly related to the integrated box 12 that installs various weighing, liquid level sensing and relays, analyzes and displays various curves, and installs various weighing devices and corresponding analysis The integrated box 12 that processes and displays relevant data curves obtains all sensor signals for data collection, and then sends the relevant data to the virtual signal analysis processor 13 for centralized processing and analysis to obtain various required results. The relay switching signals output by the processor in sequence are connected to the solenoid val...

Abstract

The invention discloses an integrated detector for slurry viscosity and rock debris granularity. The detector integrates a funnel viscosimeter with a granularity separation screen, implements sequential control automatically to complete screening, weighing and testing based on virtual type signal analyzing software and hardware technologies, and can analyze and figure out the slurry viscosity, the rock debris granularity and the distribution of the slurry and the rock debris. The detector can be directly installed near a well mouth, from which well-site drilling fluid returns to the ground, for sampling and real-time detection, and reflects valuable information about a drilling well and geology for the first time, thereby providing a basis for optimizing drilling parameters and using solid control system devices correctly and reasonably by a drilling crew. For instance, a drilling engineer can choose screens with different meshes according to particle sizes so as to improve a solid control screening effect, and the like. At the same time, the detector is one of indispensable sensing systems in an intelligent type vibrating screen working condition monitoring link. According to the detector, the funnel viscosimeter is modified simply and automatically, so that the measurement accuracy is increased; and technologies related to the vibrating screen are applied to the granularity detection, so that test automation is achieved and a requirement for well-site informatization is adapted.

Description

technical field [0001] The invention belongs to the technical field of detection, and relates to an integrated detector capable of automatically measuring the return slurry viscosity, cuttings particle size and distribution thereof in mud drilling. Background technique [0002] With the continuous improvement of the new drilling technology at home and abroad and the level of excavation technology in underground space engineering, it is necessary to keep abreast of the drilling conditions and the information of the underground (or in the excavated cave) in order to adjust the drilling parameters correctly and timely, improve the drilling efficiency and Quality has become an increasingly urgent need, but at present there are no effective online instruments and means at home and abroad. [0003] The comparison of mud viscosity before and after entering the well, the particle size and distribution of the regurgitated cuttings reflect the drilling conditions and downhole informat...
