Problems solved by technology

The automatic mineral identification system technology can measure the content of clay minerals in cuttings, but the rock properties of glutenite reservoirs are highly heterogeneous, and the content of clay minerals in the skeleton particles has a great influence on the results, which will make the content of clay minerals higher, and There are too many factors affecting the types and contents of clay minerals in the glutenite reservoir matrix, and it is difficult to distinguish

Embodiment 1

[0080] Example 1 Analysis method of clay minerals in cutting matrix

[0081] S4, take the cuttings to be analyzed for sample preparation, and obtain cuttings samples:

[0082] The sample preparation includes the following steps:

[0083] (1) Cuttings pretreatment: screen the cuttings to obtain cuttings with a particle size of 0.5-1mm, and manually remove impurities such as false cuttings and wellbore blocks, and clean them to remove the surface of the cuttings particles. The attachments and drilling fluid are thoroughly removed and dried to obtain pretreated samples.

[0084] (2) Sample preparation: Take 2.0-2.5g of the pretreated sample, put it into the mold, add the sample resin liquid composed of metallographic powder and metallographic liquid with a mass-to-volume ratio of 1:1.1, stir well to eliminate air bubbles, and let it stand. Curing for 30-60min to obtain a coarse sample;

[0085] (3) Grinding and polishing the rough sample, performing conductive carbon plating t...

Abstract

The invention discloses a method and application for rapid quantitative analysis of clay minerals in glutenite cuttings matrix. The method is based on the automatic identification technology of mineral particles of BSE map, and a core-based matrix and gravel differentiation standard is established by using the core. Qualitative division of the matrix and gravel in the glutenite cuttings can accurately and quickly analyze the clay mineral information in the glutenite cuttings matrix. The invention abandons the dependence of the traditional stratum clay mineral information analysis on the core, realizes the analysis of the clay mineral information in the stratum by using the cuttings, and greatly reduces the sampling cost.

Description

technical field [0001] The invention belongs to the technical field of mineral particle identification, and in particular relates to a method and application for rapid quantitative analysis of clay minerals in a glutenite cuttings matrix. Background technique [0002] Effective identification of the total amount, composition and relative content of various types of clay minerals in the drilling process can design the performance of drilling fluids, avoid engineering accidents such as diameter reduction and sticking, and reduce reservoir damage caused by clay mineral expansion. Effectively protect the reservoir; in the subsequent fracturing design process, suitable fracturing fluid can also be selected to avoid damage to the deep reservoir and improve the stimulation effect. [0003] The types and contents of clay minerals in traditional research are mainly obtained from logging data and laboratory core X-ray diffraction (abbreviation: XRD) analysis. Natural gamma spectrosco...
