Artificial well wall sand control simulation test device and test method

Abstract

The present invention relates to an artificial well wall sand control simulation test device and a test method, wherein the test device at least includes: a cylinder body, which can accommodate fillers constituting the artificial well wall; two ends of the cylinder body respectively An end cover is sealed and fixed, and a liquid inlet is provided on one of the end covers, and a liquid outlet is provided on the other end cover. The invention can fill the barrel with different types of formation sand and resin sand, so that simulation tests can be carried out on the artificial well wall sand control conditions of different blocks and different oil wells. The artificial well wall sand control simulation test device of the present invention is simple in structure and convenient in use and operation. In addition, the test method of the present invention can not only simulate the process of oil well artificial well wall sand control construction under corresponding test conditions, but also simulate the process of oil well production after oil well artificial well wall sand control, so as to effectively guide sand control The purpose of construction design and site sand control construction.

Description

Technical field [0001] The invention relates to a test device and a test method, in particular to an artificial wellbore sand control simulation test device and a test method that can simulate the sand filling quality and sand filling effect of a deficit formation for oil field production projects. Background technique [0002] With the continuous development of oilfields, the formation sand will gradually flow into the bottom of the well with the output of crude oil, especially for loose sandstone formations, the problem is more serious. As the formation sand is produced, a deficit zone will appear near the bottom of the well. Cause the phenomenon of wellbore sand plugging or sand buried production pipe string. In order to ensure the normal production of oil wells, usually between the formation wellbore and the casing running into it, gravel or resin sand and other materials are filled to form a gravel artificial well wall or wall with a certain strength and permeability outsid...

Problems solved by technology

However, this known test device can only carry out the sand control simulation test of horizontal well gravel packing at normal temperature, and cannot realize the simulation test function of the artificial well wall sand control formed by formation sand and resin sand cementation.

[0004] The above-mentioned known simulation test devices and methods cannot obtain the artificial well wall model designed for the stratum before forming the artificial well wall composed of formation sand and resin sand in the deficient formation, and test the resin sand under normal temperature and high pressure, high temperature and high pressure state. , sand filling quality and sand filling effect of artificial gravel, the influence of various factors on sand control effect, construction parameters required for sand filling, and sand control ability data of different types of resin sand, so it is not conducive to artificial well wall sand control construction in oil fields Operation
