Abstract
The invention provides a sand-filled pipe device simulating a two-dimensional drill core. The device comprises a circular truncated cone shaped cylinder body; a sealing cover A and a sealing cover B are arranged on the cylinder body; and a sealing pipeline connector a and a sealing pipeline connector b are arranged on the sealing cover A and the sealing cover B respectively. The combination device provided by the invention can simulate the variation of seepage velocity caused by the variation of the center distance between a working solution and a pitshaft when the working solution seeps in stratums, and can simulate the variation of the performance of the working solution caused by the variation of the seepage velocity. The sand-filled pipe device can be extensively applied in the process of improving recovery efficiency by chemical displacement in an oil field.
Description
Technical field
The present invention relates to a kind of fill out sand tube device, belong to the oil field and annotate the stratum analogue means that gathers in the lab simulation technology that improves recovery ratio in the field.
Background technology
Annotate in the poly-field in the oil field, by fluid being flowed through core or filled quartz sand or the core fill out sand tube of the sand of appearing, by record relevant seepage parameters such as parameters such as pressure, flow velocity, obtain the information that needs then, the various designs that improve recovery ratio for the oil field provide reference frame.
At present, core or the fill out sand tube majority in the indoor seepage flow flow process is one dimension.So-called one dimension be exactly core or fill out sand tube all be isometrical, the change in size of having only axial length at the identical direction fill out sand tube of seepage flow, there is not change in size radially, this analogue means can not reflect in the actual displacement process variation of the seepage flow flow velocity that the variation with distance wellbore centre distance causes well, therefore has limitation in the lab simulation process.
Summary of the invention
The purpose of this invention is to provide a kind of fill out sand tube device of simulating two-dimentional core.
