The embodiment of the invention provides a method for determining a development scheme based on seepage resistance of two-phase fluid in shale nanopores. The two-phase fluid comprises a water-phase fluid and an oil-phase fluid; the method comprises the following steps: collecting fluid parameters corresponding to at least one group of experimental samples, wherein the experimental samples have different test factor attribute values corresponding to the test factors, the fluid parameters comprise a contact angle parameter between a water-phase fluid and an oil-phase fluid; screening resistance control factors from test factors according to the fluid parameters; calculating the two-phase fluid seepage resistance of the target stratum based on the resistance control factor; and determining a development scheme by utilizing the seepage resistance of the two-phase fluid. According to the method, the determination of the development scheme is guided, the effectiveness of the scheme is improved, and the normal production development is ensured.
Description
technical field [0001] The embodiments of this specification relate to the technical field of formation exploration and development, and in particular to a method for determining a development plan based on the seepage resistance of two-phase fluids in shale nanopores. Background technique [0002] Before exploiting the reservoir resources in the reservoir, it is often necessary to obtain the geological parameters in the reservoir, and based on the geological parameters to simulate the parameter changes in the development process, and then specify the corresponding mining plan. Among them, in the process of exploiting oil reservoir resources, whether it is the starting pressure of crude oil flowing from a static state or the flow resistance of crude oil in the process of flowing in the formation, there is a certain influence on the extraction process. Especially when exploiting shale oil, especially in the micro-nano pores of shale, because the capillary pressure of shale oi...
