Nonequalized production influx along a horizontal or inclined wellbore is believed to be responsible for early water/gas breakthrough in oil-production wells. Nonequalized water-injection distribution has been recognized as a cause of poor sweep efficiency in waterflooding. The nonequalized fluid flow is attributed to reservoir heterogeneity and frictional pressure drop along the wellbore. A practical means of minimizing the problem is to use inflow control devices (ICDs) between isolation packers to adjust the production influx or injection distribution within the isolated compartments. However, the ICDs are passive devices (i.e., once they are set in place in a completion string, they cannot be adjusted to ensure equalized flow when reservoir conditions change during oil production or water injection). This paper introduces a new technology called the multinode intelligent well system (MNIWS) that is under development and will be soon available to the industry.Starting with analyzing the data from an existing horizontal well with an ICD installation, a different completion design scenario was investigated for the well using the MNIWS. Computer modeling of well performance shows that the MNIWS technology suite can equalize production influx and delay water breakthrough into the horizontal wellbore more effectively than the conventional ICD completion when the inflow condition changes during the well's life.

Based on the deep-water high temperature and high pressure LS25 gas field in the Nanhai Reservoir, through the design of heterogeneous formations and the design of water control experimental schemes, physical simulation experiments of different gas reservoir water control processes have been completed, focusing on evaluating the variable density compound water control technology based on continuous packers. In terms of the adaptability of deep-water gas reservoirs, on this basis, combined with the experiment-mine scale conversion method, a water-controlled exploitation plan for deep water high-temperature and high-pressure gas reservoirs is given. The experimental results show that: (1) Under elastic production conditions, the water body of the bottom water in the gas reservoir rises in a “progressive” manner in the initial stage, and generally develops in a “cone progression” in the middle and late stages. (2) There are obvious differences in the effects of various water control processes. A single continuous sealing body has no obvious effect on bottom water control during the gas production period of a gas well, and a single variable density screen process has no obvious effect on water control in the early stage of gas well production. The effect is good, but the risk of water channeling cannot be avoided after the gas well breaks through. The experimental effect of the variable density composite water control process based on the continuous packer is good, and the bottom water coning effect has changed to a certain extent. The experiments show that the water-free gas production period of the composite water control process is 13.7 years, the total gas production time is extended to 15.8 years, the total gas production after water control is as high as 12.37×108m3, and the recovery rate of gas wells is 9.2%, which is higher than that of elastic production. The research results aim to establish an optimal water control development model for high temperature and high-pressure deep water gas reservoirs and provide a good technical support for rational and scientific research on water control in horizontal wells of offshore deep water gas reservoirs.
