Problems solved by technology

At present, with the development of conglomerate reservoirs, especially the strong heterogeneity of deep conglomerate formations will cause the drill bit to be impacted by severe and irregular loads, and the abrasiveness of conglomerate with different gravel volume content, particle size and composition will be different. Larger, the commonly used CAI evaluation method and equivalent quartz content method are difficult to apply in conglomerate formations, but rock abrasiveness is an important factor affecting drill bit wear, which is of great significance for bit selection, drilling parameter selection, and reducing drilling costs

Abstract

The invention relates to an evaluation method and a correction method of a conglomerate stratum rock abrasiveness parameter. The evaluation method and a correction method comprises the following steps: calculating abrasiveness parameters of a rock sample according to logging data of the rock sample, wherein the logging data comprises density logging data, resistivity logging data, neutron porosity logging data, natural gamma logging data and acoustic logging data. According to the method, density logging information, resistivity logging information, neutron porosity logging information, acoustic logging information and natural gamma logging information are used for directly evaluating the rock abrasiveness parameters of the conglomerate stratum, calculation is easy and convenient, cost is low, and the method has important significance on conglomerate stratum drill bit type selection, efficient rock breaking drilling and cost reduction and efficiency improvement of drilling engineering.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to an evaluation method and a correction method of rock abrasiveness parameters in conglomerate formations. Background technique [0002] During the drilling process, the drill bits are dulled by the wear and tear of the rock and need to be replaced after a period of use. The abrasiveness parameter of the rock is an important parameter to quantitatively reflect the ability of the rock to wear the cutting teeth of the drill bit. At present, with the development of conglomerate reservoirs, especially the strong heterogeneity of deep conglomerate formations will cause the drill bit to be impacted by severe and irregular loads, and the abrasiveness of conglomerate with different gravel volume content, particle size and composition will be different. Larger, the commonly used CAI evaluation method and equivalent quartz content method are difficult to apply in conglomerate formation...
