Abstract

The invention provides a fracturing acidification working solution dynamic filtration loss instrument, which relates to the field of petroleum industry. The fracturing acidification working solution dynamic filtration loss instrument consists of a filling system (1), a rock core clamping device (2), a ring pressure tracking pump (3), a pressure return control system (4) and a metering system (5), wherein the filling system (1) is connected with the rock core clamping device (2), the rock core clamping device (2) is connected with the ring pressure tracking pump (3), the ring pressure tracking pump (3) is connected with the pressure return control system (4), and the pressure return control system (4) is connected with the metering system (5). The invention can accurately test the liquid seepage rate and the seepage rate gradient, can perfectly research formation sensitivity evaluation, oil extraction process and extraction yield improvement, and has the advantages of reasonable structure, artistic and elegant appearance, convenient operation and durability.

Description

Technical field: [0001] The invention relates to the field of petroleum industry, in particular to a dynamic fluid loss instrument for fracturing and acidizing working fluid. Background technique: [0002] Since entering the 21st century, the world's energy crisis has occurred, and the international oil price has remained high. In this severe situation, to ensure the maximum development of oil and gas resources, it is necessary to protect the oil and gas reservoirs and avoid undue damage during the development process. And some advanced petroleum instruments are also essential, such as fluid loss meters, but now many fluid loss meters are simulating formation pressure, and the conditions of formation temperature cannot accurately measure liquid permeability and permeability gradient. , the evaluation of formation sensitivity is not thorough enough, and some tests of oil production technology research cannot accurately measure the data for analysis.
