Oil production gathering and transportation process and its safety technology

in the process of oilfield production, the simple collection, measurement, transportation and initial operation of the oil well produced products (oil, water mixture and natural gas) also has the following advantages: the process of step treatment and storage is called oil production gathering and transportation process or gathering and transportation system. Due to the different sequence of each link of the gathering and transportation system or the different process facilities and structures between some links, different oil production gathering and transportation processes are formed

(1) standard process

① single tube metering station process. The process of single well and single pipe metering station, after metering respectively, the oil and gas are transported to the transfer station for centralized treatment is called single pipe metering station process. This process is applicable to oilfields with good crude oil properties (low viscosity, low wax content, low freezing point), high single well production and high wellhead pressure

② double pipe metering station process. The double pipe mixing hot water (or hot oil) is transported to the metering station for insulation. After being measured separately, the oil and gas are transported to the transfer station for centralized treatment. The mixed active hot water (or hot oil) is supplied by the metering station (room), which is called the double pipe metering station process. This process is applicable to oilfields with poor oil properties (high viscosity, high freezing point, high wax content), low single well production and low wellhead pressure

(2) non standard process. Except for the single (double) tube metering station process, other processes are non-standard processes. For example, the oil and gas distribution (double pipe) process measures the stress change on the sample and the three pipe hot water accompanying process. Some non-standard processes are selected to adapt to the characteristics of specific oil fields, so as to save costs; Some are formed before the application of the standard process, and have not been transformed

2. the principle of selecting the oil production gathering and transportation process

(1) the process has strong adaptability. Meet the geological characteristics of the oilfield and the physical property requirements of crude oil; Meet the initial production of the oilfield and facilitate the adjustment and transformation of the oilfield in the middle and later stages

(2) oil and gas tight closed gathering and transportation to minimize oil and gas loss

(3) make rational use of formation energy, reduce power and heating equipment as much as possible, and save electricity and fuel

(4) all links of the process should be matched. Adopt advanced technology and equipment to treat oil, gas and water and produce qualified products. It is conducive to crude oil dehydration, oil and gas separation, and natural gas dehydration of light oil; It is conducive to the recovery of natural gas, sewage and light hydrocarbons, and prevents environmental pollution

(5) measurement instrumentation, automatic production, special testing machine for Jinan assay ring stiffness, reduce production management personnel, and improve production management level and labor productivity
