Abstract

The invention relates to a visible elasticity testing instrument and testing method for an elastic microsphere and belongs to a technology for evaluating a modifying and flooding agent for tertiary oil recovery in an oil field. The visible elasticity testing instrument mainly comprises a gas source, an intermediate container, 2-5 reducer pipes and a receiving container, wherein one reducer pipe comprises 2-3 different reducing parts to simulate a porous stratum system. The strength of the elastic microsphere is characterized through recording the maximal pressure acting on the elastic microsphere passing through the reducing parts, meanwhile, the average strength of one group of elastic microspheres and a number of the elastic microspheres passing through the reducer pipes under different pressures can be measured so as to select elastic microspheres suitable for different stratums. The visible elasticity testing instrument has the advantage of well simulating a capillary network structure in which wide and narrow holes in the stratums are strung together. In addition, the instrument is simple to operate.

Description

1. Technical field [0001] The invention relates to a device for evaluating the performance of a regulating and displacing agent in oil and gas field exploitation, and is specifically described as an elastic microsphere strength measuring device and a measuring method thereof. 2. Background technology [0002] As the oilfield enters the later stage of development and production, the difficulty of production becomes more and more serious. The traditional profile control technology is limited by the difficulty of production and cannot meet the needs of oilfield profile control. In order to meet the needs of deep profile control technology, elastic microsphere deep profile control technology came into being. Elastic microspheres are a deep control and displacement agent that matches the size of reservoir rock pore throats. When they exist in rock pores, they can hinder or block water flow, and a large number of microspheres have Migration, plugging, elastic deformation, re-migr...
