Abstract: A high-temperature resistant, high-strength, and thixotropic gel plugging agent is composed of 8-20% of acrylamide monomer, 0.05-0.5% of reactive polymer, 0.1-1.0% of organic polymer cross-linker, 3.0-8.0% of resin toughening agent, 1.0-5.0% of flow pattern regulator, 0.01-0.5% of cross-linking regulator by the weight in the water. The gel solution shows a low apparent viscosity during the shear flow and is easy to be pumped into the wellbore and then into the formation leakage layer; after the pumping stops, the gel solution shows rapidly increased viscosity and strong adhesive force, and form a high-strength barrier between the wellbore and the formation, preventing the drilling fluid from further leaking.

Abstract: The present disclosure provides a method and device for predicting a production performance of an oil reservoir. The method includes: determining a single-well numerical simulation data set according to geological parameters, rock and fluid parameters and construction data; performing reservoir numerical simulation based on the single-well numerical simulation data set, and determining a standard data set for oil reservoir production performance prediction; establishing a deep belief network (DBN) model for oil reservoir production performance prediction according to the standard data set; and predicting the production performance of a target well by using the DBN model to obtain a production performance prediction result of the target well. The present disclosure can be used to fast and accurately predict the production performance of an oil well in an unconventional oil reservoir. For a given block, the DBN model can be used indefinitely without the target well being put into production.
