Embodiment 1

[0052] figure 1 It is a schematic flow chart of an optimal design method for an oilfield gathering and transportation system according to Embodiment 1 of the present invention; figure 1 As shown, this embodiment provides an optimal design method for an oilfield gathering and transportation system, including steps 101-104.

[0053]Among them, in step 101, the initial position of the booster station is determined according to the gathering radius, the number of oil wells under the jurisdiction of the station, the processing scale of the station and the sum of the pipeline lengths of the oil wells under the jurisdiction of the station.

[0054] Specifically, the gathering and transportation radius is generally 2 kilometers or 3 kilometers. The number of oil wells under the jurisdiction of the station is the number of oil wells that need to be boosted by the booster station. The processing scale of the station indicates the scale that the booster station can boost. The premise of...

Embodiment 2

[0063] This embodiment is a supplementary description based on the above embodiments.

[0064] figure 2 It is a schematic flow chart of an optimal design method for an oilfield gathering and transportation system according to Embodiment 2 of the present invention; as figure 2 As shown, this embodiment provides a method for optimal design of an oilfield gathering and transportation system, including:

[0065] In step a1, the three-dimensional terrain data of the oilfield area where the oil well is located is obtained to obtain a terrain elevation model of the oilfield area. The terrain elevation model (DEM) is obtained by the SRTM system, and the latitude and longitude coordinates of the WGS-84 coordinate system of the ellipsoidal datum are converted into the plane Cartesian coordinates of the National-80 coordinate system of the ellipsoidal datum through coordinate conversion.

[0066] Step a2, according to the terrain elevation model, calculate the total length of oil wel...

Abstract

The invention provides a method and device for optimum design of oil field gathering and transportation systems. The method comprises the following steps of: determining an initial position of a booster station according to a gathering and transportation radium, a number of oil wells under administration of the station, a station yard processing scale and a length sum of pipelines of the oil wellsunder the administration of the station yard; optimizing the initial position of the booster station according to the length sum of the pipelines of the oil wells under the administration of the station yard and a weighting coefficient, so as to obtain an optimized position of the booster station; determining an optimum topological form of a series pipe network according to the optimized positionof the booster station and positions of the oil wells, so as to ensure that the length sum of the pipelines of the oil wells under the administration of the station yard is the shortest; and determining pipe diameters and wall thickness parameters of the pipelines according to the optimum topological form. According to the method and the device, an objective method and theoretical basis are provided for the layout of stations of series pipe network gathering and transportation systems and the optimum design and planning of pipeline connection and parameters, so that the defects of subjectivejudgment relaying on personal experiences and habits are avoided, and benefit is brought to reduce construction investment and operation expenses of the gathering and transportation systems.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to an optimization design method and device for an oil field gathering and transportation system. Background technique [0002] Oilfield surface oil and gas gathering and transportation system is one of the backbone projects of the surface engineering of oilfield production capacity construction, and its investment generally accounts for 60% to 70% of the entire surface engineering, mainly for pipeline network and gathering and transportation station investment. At the same time, the thermal energy and kinetic energy of the oil and gas gathering and transportation system consume a lot, generally accounting for 30% to 40% of the total energy consumption of crude oil production. Therefore, the optimal design of the gathering and transportation system is very important for reducing investment and operating costs. [0003] For a long time, when designing the construction scheme of...
