Rock debris logging detection system

Abstract

The invention relates to the technical field of petroleum drilling, and particularly relates to a rock debris logging detection system. The rock debris logging detection system comprises a collecting end, a detecting end and a background end, wherein a plurality of collecting units of the collecting end are used for collecting rock debris samples of all stratums; the detecting end is used for detecting the rock debris samples of the stratums at all depth points and generating rock debris detection information; the background end is used for receiving and processing the rock debris detection information from the detecting end; a data analysis subsystem of the background end can calculate the total value of element radioactive energy according to the rock debris detection information of the stratums at all the depth points and draw a to-be-compared stratum map; and a data comparison module of the data analysis subsystem can extract a to-be-compared stratum curve in the to-be-compared stratum map, calculate curve similarity values of the to-be-compared stratum curve and all reference stratum property curves and output corresponding stratum properties according to a reference stratum property map of the reference stratum property curve closest to the to-be-compared stratum curve.

Description

technical field [0001] The invention relates to the technical field of oil drilling, in particular to a logging detection system for cuttings. Background technique [0002] It is necessary to judge the formation properties of strata at different depths before oil well operation and oil production, and design the development plan during the oil drilling process according to the formation properties of different depths. According to the formation properties, drilling engineers can adjust the specific gravity, composition and drilling mud of drilling mud in advance. parameters, thereby making drilling safer. [0003] For oil and gas exploration and drilling engineering, formation property information is mainly obtained through cuttings logging. At present, the identification method for the formation properties of the formation where the oil well is located is mainly through drilling and coring, generally sampling and testing cuttings every 1 meter or 2 meters, observing the cu...

Problems solved by technology

At present, the identification method for the formation properties of the formation where the oil well is located is mainly through drilling and coring, generally sampling and testing cuttings every 1 meter or 2 meters, observing cuttings and analyzing the mineral components in the cuttings to determine the nature of the formation , however, due to the large number of mineral components in the cuttings, and the detection and analysis of the composition of the cuttings at each level, it is time-consuming and labor-intensive, and the accuracy of this method for describing the stratigraphic properties of the formation where the cuttings are located low, there is a large deviation between the judgment result and the real situation
