Study on Optimization of Anticorrosion Technology for Valve Pit Facilities in Tahe Oilfield

Highlights in Science, Engineering and Technology, 2022
Due to the abundant underground water source, the structure of the valve pool, the non installation of water stop flange in the crossing pipeline and other problems, the leakage disease rate of the valve pool in Tahe oilfield reaches more than 80%. If it is not treated in time, the valves, pipe fittings and other facilities will be rusted, which will ...

Productivity Prediction of Fractured‐Vuggy Reservoirs under Time‐Varied Flow Rates and Bottom Hole Flow Pressures

Geofluids, Volume 2022, Issue 1, 2022., 2022
Fracture‐vuggy oil reservoirs contain micrometer‐sized dissolved secondary pores, fractures, and meter‐sized karst caves. Generally, the researches on the flow mechanism of fractured‐vuggy reservoirs are based on the assumption of karst cave‐fracture‐matrix triple medium that gives a partial differential equation which the pressure satisfies.

Experimental Study on Production Characteristics of Bottom Water Fractured‐Vuggy Reservoir

Geofluids, Volume 2022, Issue 1, 2022., 2022
To assess the high‐pressure production characteristics of double‐vug reservoirs with bottom water in the Tahe Oilfield, in this study, a high‐pressure physical simulation experiment apparatus is built for double‐vug reservoirs with bottom water. The high‐pressure production characteristics of “vug‐fracture‐vug” reservoirs under different bottom water ...

Temperature-resistant and salt-tolerant mixed surfactant system for EOR in the Tahe Oilfield [PDF]

Petroleum Science, 2021
AbstractA new temperature-resistant and salt-tolerant mixed surfactant system (referred to as the SS system) for enhancing oil recovery at the Tahe Oilfield (Xinjiang, China) was evaluated. Based on the analysis of the crude oil, the formation water and rock components in the Tahe Oilfield, the long-term thermal stability, salt tolerance and the ...

Experimental Study on Chemical Recovery of Low‐Permeability and Medium‐Deep Heavy Oil Reservoir

Geofluids, Volume 2022, Issue 1, 2022., 2022
To improve the oil recovery of a block in the Wutonggou Formation of the Changji Oilfield, viscosity reducing and foaming agent was optimized to improve the development effect of the water flooding reservoir. The core flooding experiment and microscopic visual experiment were conducted to investigate the production characteristics and EOR mechanism of ...

Nanopore Confinement Effect on the Phase Behavior of CO2/Hydrocarbons in Tight Oil Reservoirs considering Capillary Pressure, Fluid‐Wall Interaction, and Molecule Adsorption

Geofluids, Volume 2021, Issue 1, 2021., 2021
The pore sizes in tight reservoirs are nanopores, where the phase behavior deviates significantly from that of bulk fluids in conventional reservoirs. The phase behavior for fluids in tight reservoirs is essential for a better understanding of the mechanics of fluid flow.

A New Model for Predicting Flow in Fractured‐Vuggy Carbonate Reservoirs under Pseudosteady State Condition

Geofluids, Volume 2021, Issue 1, 2021., 2021
For constant rate production of a single well in a closed boundary fractured‐vuggy carbonate reservoir, when the pressure wave propagates to the reservoir boundaries, boundary‐dominated flow occurs, and the transient flow period ends, the reservoir will be in a state of pseudoequilibrium (i.e., pseudosteady state flow occurs, and the pressure at any ...

Relationship between Faults and Hydrocarbon Distribution in Tahe Oilfield Southeast Slope [PDF]

Proceedings of the 2015 6th International Conference on Manufacturing Science and Engineering, 2015
Fault in Tahe Oilfield southeast slope has a positive meaning for more oil and gas reservoir, it can be divided into eight groups. Three of them have significant control action for the gas-water including north-south, NNE and NEE. They have closely related with fracture and karst reservoir seam holes, karst cave reservoirs and fractured reservoirs ...
