渤西油田群联合开发及半海半陆式工程方案的确定

The Joint Development of Boxi Oil Fields Group and the Semi - offshore and Semi - onshore Concept

本文系统地阐述了渤西油田群联合开发思路的形成和“半海半陆式”工程方案的确定过程。采用“全海式”开发工程方案单独开发歧口18-1油田的经济测算表明,该油田无经济效益。而油藏研究结果显示,以歧口18-1油田为中心、以15km为半径的范围内所发现的歧口17-3、歧口17-2及曹妃甸13-1等油气田均获高产油气流,并有可观的石油地质储量。工程专家以此为基础,提出渤西水浅离岸近,可充分依托陆地,建成“半海半陆式”工程设施,以歧口18-1油田为集输中心,把几个油气田生产的油气流全部汇集到18-1油田后再通过2条管线把油水和天然气输送上岸进行处理。联合开发思路和“半海半陆式”工程方案为渤海四大开发体系的形成奠定了物质技术基础。

The paper systematically describes the concept development for Boxi oil fields group joint development and the decision making process of semi -offshore and semi - onshore engineering program. As indicated by the economics model, it would not be economical if QK18 - 1 is developed on a stand alone basic by using whole offshore mode. The reservoir study shows that, considerable reserves lie in the area centered by QK18 - 1 oil field with a radius of 15 km, where a number of productive discoveries such as QK17 - 3, QK17 - 2 and CFD13 - 1 have been found. On these basis, engineers proposed a semi - offshore and semi - onshore concept due to the shallow water and close distance to shore, i. e. QK18 - 1 oil field acts as a gathering center to collect the production fluids from several other oil fields, then transport the oil and water in one line and natural gas in another line to onshore for treatment. This joint development set a sound material and technical foundation for the formation of four development systems in Bohai Gulf.
