琼东南盆地的崖13-1大气田即将投入开发,它是国内目前规模最大的高产气田,储量近1000×10~8m~3,单井最高无阻流量达1000×10~4m~3/d,储层厚度大、物性好,储量丰度高,是一个潜山披覆背斜。它具有统一气水界面,是一边水不活跃的块状气藏。国内在开发碳酸盐岩气田和中小规模的砂岩气田方面有许多成功的经验,但对开发海上高产大气田尚无实例。在编制和审查崖13-1气田开发方案时,对井网、布井方式、井数、产能、开采速度、采出程度、稳产年限应如何确定有许多不同见解。本文主要介绍国外某些砂岩大气田,特别是海上砂岩
Cliff 13-1 gas field in Qiongdongnan Basin is about to be put into development. It is the largest high-yield gas field in China with reserves of nearly 1000 × 10 ~ 8m 3. The maximum unimpeded flow in single well reaches 1000 × 10 ~ 4m 3 / d, Thick reservoir thickness, good physical properties, high abundance of reserves, is a buried mountain anticline. It has a uniform gas-water interface, is a block of water is not active block gas reservoir. There are many successful experiences in the development of carbonate gas fields and small and medium-sized sandstone gas fields in China, but there are no examples to develop large-scale offshore gas fields. There are many different opinions on how to determine the well pattern, well pattern, well number, production capacity, mining speed, production recovery and stable production when formulating and reviewing the Ya 13-1 gas field development plan. This paper mainly introduces some foreign sandstone gas fields, especially offshore sandstone
