Problems solved by technology

Due to the large number of fracturing stages and the differences in physical properties in long horizontal sections, the fluid drainage after each stage of fracturing is of great significance for the evaluation of fracturing effects and the deployment of well locations in the next step, but for each stage after staged fracturing There is no effective monitoring method for oil production

Embodiment 1

[0030] Dissolve 1g of polyvinyl alcohol (average degree of polymerization 2400-2500) in 55g of hot water, raise the temperature to 75°C for 30min, slowly add 40g of 2-hydroxyethyl acrylate, 4.5g of styrene and 0.9g of peroxide The mixed solution of benzoyl was reacted for 8 hours after the dropwise addition, cooled to room temperature and discharged.

Embodiment 2

[0032] Dissolve 1.5g of polyvinyl alcohol (average degree of polymerization 2400-2500) into 65g of hot water, raise the temperature to 75°C for 30min, slowly add 30g of 2-hydroxyethyl acrylate, 4g of styrene and 0.6g of peroxide The mixed solution of benzoyl was reacted for 8 hours after the dropwise addition, cooled to room temperature and discharged.

Embodiment 3

[0034] Dissolve 2g of polyvinyl alcohol (average degree of polymerization 2400-2500) into 70g of hot water, raise the temperature to 75°C for 30min, slowly add 25g of 2-hydroxyethyl acrylate, 3g of styrene and 0.5g of styrene peroxide dropwise The mixed solution of formyl was reacted for 8 hours after the dropwise addition, cooled to room temperature and discharged.

Abstract

The invention provides polystyrene acrylic acid-2-hydroxyethyl ester, and a synthetic method and application thereof. The polystyrene acrylic acid-2-hydroxyethyl ester is prepared by using the method comprising the step of carrying out suspension polymerization reaction with acrylic acid-2-hydroxyethyl ester and styrene as reaction monomers and water as a dispersion medium in the presences of a dispersing agent, i.e., polyving akohol, and an initiator, i.e., benzoperoxide. The polystyrene acrylic acid-2-hydroxyethyl ester provided by the invention has the following advantages: test results show that the polystyrene acrylic acid-2-hydroxyethyl ester synthesized by using the method in the invention can be completely dissolved in crude oil, and the concentration of the obtained mixed solution can be accurately determined via a gas chromatograph-mass spectrometer; less usage amount is needed; and the need of monitoring horizontal-well oil-production profile is met.

Description

technical field [0001] The invention relates to the field of petroleum exploration and development, in particular to a polystyrene-2-hydroxyethyl acrylate and its synthesis method and application. Background technique [0002] At present, in the process of oilfield exploration and development, horizontal wells are mostly used for exploration wells, and multi-layer and multi-stage fracturing is the preferred process for formation stimulation. However, in the process of layer selection, there is no pertinence, and layers are selected based on experience. Therefore, It is particularly important for data collection and analysis of fracturing effects after fracturing. In the prior art, the development of fractures after fracturing can be monitored and analyzed by microseismic method, potential method, etc., and whether there is industrial oil flow in the reservoir can be known through the flowback situation, but for the oil production of each stage after staged fracturing There ...
