Embodiment 1

[0034] Embodiment 1: Taking a rock polarizability measuring device as an example, the present invention is further described in detail.

[0035] refer to figure 1 . The rock polarizability measurement device is mainly composed of three parts: core holder, solution circulation system and measurement panel.

[0036] refer to figure 2 . The core holder is mainly composed of a left conduit 21, a left end cover 24, a left clamp 5, a left pressure block 25, a core chamber 6, a core metal sleeve 27, a core rubber sleeve 26, a right pressure block 28, a right clamp 8, and a right end cover 30, adjusting nut 10, right conduit 13 and rock core room support 19 form. The rock core chamber 6 is in the shape of a cylinder, and the two ends of the rock core chamber 6 are respectively provided with outwardly protruding frustum-shaped fixing blocks. The core chamber 6 is embedded with a composite core sleeve. The structure of the composite rock core sleeve is that a cylindrical rock cor...

Abstract

A device for measuring polarizability of rocks is applied to the field of measurement of rocks in petroleum geology and is used in the laboratories under normal temperature. The device is characterized in that the whole device is mainly composed of a core holder, a solution cycling system and a measurement panel, wherein the core holder is of clip structure; the solution cycling system is reasonable in structure; water nozzles of measuring chambers of the solution cycling system are provided with valves; the measuring system dispenses with external standard modules or reference modules while carrying out zero graduation; and the measuring process is controlled by the computer. The invention has the following effects: the invention provides a clip structured core holder which is quite convenient to assemble and disassemble for measuring the polarizability of rocks in the laboratories, the solution cycling system ensuring the measuring result of the polarizability of rocks to be slightly affected by external polarization potential and the device panel which is reasonable in structure and convenient to operate.

Description

technical field [0001] The present invention relates to the technical field of petroleum geological rock measurement devices, in particular to the technical field of rock electrochemical parameter detection, and is a device for measuring rock polarizability in a laboratory under normal temperature conditions, including a core holder, a solution circulation system and Measurement panel. Background technique [0002] The polarizability of ore-bearing rocks is much greater than that of non-mineral ones. In similar ore-bearing rocks with the same structure, the polarizability begins to increase significantly with the increase in the volume content of conductive minerals. Polarizability is largely influenced by rock structure. In addition, the polarizability is also related to factors such as the concentration of formation water contained in rock pores. [0003] Patents related to rock polarizability include: Chinese Patent Publication No.: CN101000379A, which provides a metho...
