Abstract

The invention relates to a multi-channel reservoir physical model of heavy oil thermal production well to be constructed. According to the model, a filling channel group which covers three penetration rate ranges of high, middle and low levels and is filled with oil-water with different degrees is prepared by stratum sand, crude oil and stratum water, or simulation stratum sand, simulation crude oil and simulation stratum water. By use of the model, in site channel sealing and water plugging by plugging agent injecting, solidification and plugging effects in a construction well of heavy oil thermal production are accurately simulated. Thus, simulation test of channel sealing and water plugging in heavy oil thermal production well is carried out, plugging agent property is regulated and optimized, and construction control data of in site channel sealing and water plugging in heavy oil well is tested and acquired to provide guidance for compiling construction designs of channel sealing and water plugging, to increase success rate of channel sealing and water plugging construction and to increase production. By applying the physical model and corresponding test method in guiding selective channel sealing and water plugging in site of heavy oil thermal production well, great economic benefit and social benefit will be brought about and the application aspect is quite broad.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to a multi-channel reservoir physical model of a well to be constructed in thermal recovery of heavy oil and its simulation experiment method and application. The multi-channel reservoir physical model of the well to be constructed and its simulation experiment method and application. Background technique [0002] At present, the structure of world oil supply is constantly changing. The proportion of heavy oil production in domestic crude oil production has been increasing year by year. Due to the high viscosity of heavy oil, it is difficult to develop, and thermal recovery is basically adopted for development. Compared with the development of ordinary crude oil, there are problems such as high energy consumption, channeling of injected steam, and high water cut in oil wells. With the deepening of heavy oil reservoir development, Sinopec Shengli Oilfield, Henan Oilfie...
