Embodiment Construction

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0032] Such as figure 1 Commonly shown, a method for measuring the total porosity of broken shale samples, comprising the following steps:

[0033] S1, such as figure 2 As shown in (a), small rigid particles are placed in the sample tube of the appearance volume measuring instrument, the size of the small rigid particles is less than 60 mesh, and the volume does not exceed 2 / 3 of the sample tube.

[0034] Preheat the appearance volume measuring instrument, clean the dust in the sample tube, prevent the small rigid particles from contaminating or adhering to the surface of the sample to be measured, and correct the instrument to ensure that the position where the bolus plug starts to measure is zero.

[0035] S2. ...

Abstract

The invention relates to a measurement method for the total porosity of a shale crushed sample. The needed sample quantity is relatively small and influences of problems of changing original water saturation, water absorption after drying and the like in a crushing process do not need to be considered, so that external influences of experiments are reduced; an experiment flow is convenient and rapid and the precision is high; the measurement method has no requirements on shapes of shale samples, so that the cost of drilling a plunger piston sample is greatly saved; compared with measurement ofthe plunger piston sample, the measurement method can be used for effectively measuring the total porosity of shape; meanwhile, the measurement time is reduced and system errors are reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to a method for measuring the total porosity of broken shale samples. Background technique [0002] Shale porosity measurement has always been an unresolved difficulty. Shale has a high content of brittle minerals, so it is difficult to obtain a complete shale plug-like core; the mineral composition is complex, the pores are small, and the heterogeneity is strong, so it is difficult to measure the porosity accurately. The shale porosity measurement has cylinder-like porosity measurement and broken-sample porosity measurement. The cylinder-like porosity is the effective porosity of the core, and the isolated dead pores in the core cannot be obtained; the broken-sample porosity is the total porosity of the core degree, measuring all pore spaces in the core. At present, the domestic shale porosity measurement mainly adopts the plunger sample measurement method to obtain...
