Sand control simulation experiment tank

Abstract

The invention relates to a sand control simulation experiment tank, and relates to the field of sand control simulation. The main technical scheme includes that the sand control simulation experiment tank comprises a tank body, a sealing connecting seat and a filter; the tank body comprises a first end and a second end which are in opposite directions; a sand filling groove is formed in the first end, and an oil inlet hole which is communicated with the sand filling groove is formed in the second end; the sealing connecting seat comprises a third end and a fourth end which are in opposite directions; an oil outlet groove is formed in the fourth end, at least one flow hole which is perforated through the third end is formed in the bottom surface of the oil outlet groove, the third end is connected with the first end, and the oil outlet groove is communicated with the inside of the sand filling groove via the flow holes; the filter is arranged on a side of the end, which is deviated from the oil outlet groove, of each flow hole and covers an opening of the flow hole; the size and the shape of the contour of the inner edge of the sand filling groove are identical to the size and the shape of the contour of the inner edge of the oil outlet groove. The sand control simulation experiment tank has the advantage that the experiment precision of the sand control simulation experiment tank can be improved.

Description

technical field [0001] The invention relates to the technical field of sand control simulation, in particular to a sand control simulation experiment tank. Background technique [0002] Sand control completion is widely used in the completion of sand producing oil and gas wells. In general, sand production reduces the productivity of oil and gas wells, leads to excessive maintenance and repair of equipment, and the cost of workover operations is increasingly high. Excessive sand production can also lead to premature failure of wellbore and downhole equipment. Therefore, the correct sand control technology is highly valued by the oil and gas well industry. In order to effectively evaluate the sand control method and the sand control ability of sand control equipment in the formation, it is necessary to simulate and analyze the sand control effect of the equipment through sand control simulation experiments. Through the analysis of the core and crude oil of the oil-producing...

Problems solved by technology

[0004] In the process of realizing the above-mentioned technical solution, the inventors found that there are at least the following problems in the prior art: the diameter of the oil outlet hole of the sand control simulation experimental device is much smaller than the inner diameter of the inner cavity, so that the difference between the oil outlet hole and the sand control simulation experimental device Flow area varies greatly between lumens

However, in the actual application process, the flow area inside and outside the sand control screen should be close to or the same, which leads to the difference between the simulation conditions of the sand control simulation experimental device and the actual application, which in turn leads to the large discrepancy between the experimental results of the sand control simulation experimental device. error
