A sand control well reservoir testing device

Abstract

The present invention relates to the technical field of an oil field reservoir testing device and method, in particular to a sand control well reservoir testing device. There is a signal screen, an external tester is provided under the signal screen, a filter sand tube is provided under the external tester, and a blind plug is provided at the bottom of the filter sand tube; the bottom of the external tester is connected to the An in-pipe tester is installed between the filter sand tubes; the beneficial effect is that during the filling process, when the pressure exceeds the set value, the induction hole is closed to avoid damage to the tester by the high pressure; when the high pressure disappears, the induction hole Reopening again, the tester performs normal oil reservoir data measurement and storage again, so that the inner tester and the outer tester are protected. The invention is well connected with the sand control technology, does not greatly change the original sand control technology, provides technical convenience for on-site promotion, and provides convenience for refined production management in oil fields.

[0002] In the oil industry, reservoir data testing is an important technical means to assist oil extraction. Researching various technologies to find out oil reservoirs is of great significance to the development of oil. Since the electronic sensing technology has been available, people have always wanted to It is applied to oil extraction in order to obtain more direct data and make greater contributions to oil extraction. At present, electronic induction technology has been applied in some relatively simple and easy-to-apply processes, and has achieved good results. effect, but we know that at present, the exploitation of oil is in the middle and later stages, especially in China, where the geological conditions are relatively complex, the exploitation is difficult, and there are a large number of sand producing wells, and in these sand producing wells, in order to avoid severe sand production, It is necessary to carry out gravel packing on sand producing wells in oil field production, and in these wells that need to be filled, because the injection pressure during filling is relatively high, generally above 15MPa, and some require above 25MPa, and during oil production, the pressure Smaller, generally around 0.5~1MPa, such a large drop cannot be realized in the technical field of reservoir testing. The reason is very simple. If a reservoir testing device is installed, the reservoir testing device mainly relies on some sensors to realize the test, but Many sensors cannot work under high pressure difference, and are either damaged or have large errors, making the obtained data untrue and unusable
