Corrosion Law of Metal Pipeline in Tahe Oilfield and Application of New Materials [PDF]

Coatings, 2021
Frequent corrosion perforation of metal pipes severely restricts oil and gas fields’ safety production and increases maintenance costs. Therefore, it is imminent to change the characteristics of metal materials fundamentally. In this paper, taking the metal pipe of Northwest Oil and Gas Field in China as an example, for the corrosion environment with ...

Temperature Field Study of Offshore Heavy Oil Wellbore with Coiled Tubing Gas Lift‐Assisted Lifting

Geofluids, Volume 2023, Issue 1, 2023., 2023
Offshore heavy oil resources are abundant, but they have greater difficulty and higher costs compared to onshore extraction. When crude oil flows through the seawater section, the temperature of the crude oil decreases faster, making it susceptible to solidification in the wellbore and resulting in lower well production.

Stratigraphic evolution and karstification of a Cretaceous Mid‐Pacific atoll (Resolution Guyot) resolved from core‐log‐seismic integration and comparison with modern and ancient analogues

Basin Research, Volume 34, Issue 5, Page 1536-1566, October 2022., 2022
Seismic‐stratigraphic analysis of Resolution Guyot as a prime examples of the Cretaceous Mid‐Pacific atolls revealed controls from the Cretaceous eustasy on the evolution and karstification of the Cretaceous Mid‐Pacific atolls along with other factors including changes in subsidence and production rates and later magmatic activity(ies). Abstract Atolls

Research on the Depletion and Recovery Characteristics of Fault‐Karst Reservoirs

Geofluids, Volume 2022, Issue 1, 2022., 2022
A fractured‐vuggy carbonate reservoir is a special reservoir formed by long‐term physical, chemical, and geological processes. Its reserves are large in scale and widely distributed, showing the characteristics of free flow‐seepage coupling. Conventional simulation is usually simplified by equivalent permeability, which cannot reflect the actual ...

Residual Oil Distribution Pattern in a Fault‐Solution Carbonate Reservoir and Countermeasures to Improve Oil Development Effectiveness

Geofluids, Volume 2022, Issue 1, 2022., 2022
Because of the strong random distribution of fractures and caves, fault‐solution carbonate reservoirs exhibit significantly different flow mechanisms and development methods from conventional carbonate reservoirs. Natural elastic and edge‐bottom water flooding are the main processes for developing fault‐solution reservoirs.

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 ...
