复杂小断块群开发建设配套技术及其应用

Supporting Technologies for Development and Construction of Small Complex Faulted Block Groups and Their Application

华北油田霸县凹陷文安斜坡含油气断块规模小、分布零散,部分井油稠、出砂严重,地面环境条件复杂,常规采油及地面工艺难以适应。为了推动该油区开发建设工作,通过开展技术攻关、先导试验,逐步形成了限砂冷采、人工举升、地面集输、稠油处理、井点拉气、简易注水等6项配套技术,从而打开了开发建设新局面。文章介绍了这些配套技术的应用条件、具体措施及应用效果,指出复杂小断块的开发建设中采油、地面工艺技术的选择与集成,必须因地制宜、突出单井(或井组)个性化、简易实用灵活、便于管理的原则,才能取得好的开发效果。

Conventional production and surface technologies are difficult to adapt to the oil and gas bearing blocks of Wen’an slope at Ba’xian sunken in Huabei Oilfield because of small and scatteredly distributed faulted blocks with heavy oil and severe sand influx in some wells. In order to drive development and construction of the oil region, technology research and pilot test were carried out, and six supporting technologies including cold heavy oil production with sand control, artificial lifting, surface gathering, heavy oil processing, trucking gas from well site, and simple water injection were gradually developed, which opened a new statement in rolling development and construction. This paper introduced the application conditions, specific measures and application effects of the supporting technologies, and pointed out good development effect in the development and construction of complex small faulted blocks, the oil production and surface technology selection and integration must suit one’s measures to local conditions, highlighting the single well (or a group of wells), simple and practical and flexible, personalized for the convenience of management.
