Embodiment Construction

[0023] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0024] Such as figure 1 as shown, figure 1 It is a flowchart of a specific embodiment of the indoor test method for monitoring the difference in liquid production capacity between layers of the present invention.

[0025] In step 101, the sand filling pipe is filled. According to the porosity and permeability of each layer in the test block, the type of filling, pressing pressure and pressing time are determined, and the sand filling pipe with the physical properties of the simulated reservoir is filled. In one embodiment, according to the porosity and permeability of each layer with the same vertical thickness in the test simulation block A reservoir (see Table 1), three Φ2.5cm×100cm sand fillings with different permeability are filled with qu...

Abstract

The invention provides an indoor test method for monitoring the difference in liquid production capacity between layers, the indoor test method for monitoring the difference in liquid production capacity between layers comprises: step 1, filling sand filling pipes with simulated reservoir physical properties; step 2, Carry out the physical property inspection of the sand packing pipe; step 3, record the saturated oil volume of the sand packing pipe; step 4, conduct the water flooding oil test; and step 5, analyze the difference in fluid production capacity between layers. The laboratory test method for monitoring the difference in fluid production capacity between layers enriches the monitoring methods of oilfield mineral development practice, provides a basis for formulating reservoir development technology policies, and can effectively guide the development practice of multi-layer co-production reservoirs.

Description

technical field [0001] The invention relates to the technical field of oil field development, in particular to an indoor test method for monitoring the difference in liquid production capacity between layers. Background technique [0002] The monitoring of the fluid production capacity of each layer in a multi-layer reservoir is usually realized by actually measuring the fluid production profile of the reservoir. However, since the implementation of this technology affects the production well’s open-in time rate and requires specific wellhead devices, etc., It affects the normal production of oil wells, and the application scale of this technology is very limited. [0003] In addition, the current laboratory test can simulate the specific parameters required for single-layer development, such as the water pressure introduced in pages 142-144 of the book "Reservoir Engineering Methods and Applications" published by Petroleum University Press in May 2002. Conventional natural...
