复杂断块油田构造破碎、油层层数多、油气埋藏深、含油面积小、储量丰富、渗透率低,以及高温、高压、高盐的油藏特点,使得如何在复杂断块区内寻找出新的接替储量,实现油田开发储量、产量以及经济效益协调发展成为了当下一个世界性的难题,复杂断块油藏开发面临技术突破。水平井由于泄油面积大、生产压差小、产油量高,水平井开发近来被广泛应用于海上油田开采。本文通过研究丛式水平井组在复杂断块油藏开发中的应用,探讨复杂断层油藏开发新路径,对复杂断块油田的高效持续增储具有重要的现实借鉴意义。
Complicated faulted blocks are structurally fractured, multi-layer reservoirs, deep oil-gas burial, small oil-bearing area, abundant reserves, low permeability, and characteristics of high temperature, high pressure and high salinity reservoirs. Of the reserve, to achieve the coordinated development of oilfield reserves, production and economic benefits has become a worldwide problem nowadays, complex fault block reservoir development is facing a technological breakthrough. Horizontal wells due to large drainage area, the production of small pressure, high oil production, horizontal well development has recently been widely used in offshore oil field exploitation. This paper studies the application of cluster horizontal well group in the development of complex fault block reservoirs and discusses the new path of complex fault reservoir development, which is of great practical significance for the efficient and sustained increase of reserves in complex fault block fields.
