摘要

库车坳陷深层碎屑岩气田是近年来塔里木盆地天然气勘探开发的热点,该类气田具有储量规模大、埋藏深、高温高压、区块间裂缝发育差异大、边底水普遍存在等特点。气藏非均匀水侵导致气井产能快速下降,严重制约气田开发效果,是目前气田高效开发面临的普遍难题。从静态气水分布、微观水侵机理和动态水侵评价入手,系统建立了气水分布描述、水侵规律和控水开发技术对策为一体的静动态评价技术。研究认为,库车坳陷深层大气田气水分布受基质物性和缝网发育共同控制,气水分布模式可划分为两类:薄气水过渡带型(含基质物性好型和裂缝特别发育型两个亚类)和厚气水过渡带型。气水分布和裂缝发育的差异性,直接导致了气田水侵部位与水侵动态特征的不同,表现为3种水侵类型:边底水整体抬升侵入型、边底水沿微细裂缝带锥进型和边底水沿大裂缝纵窜型。基于不同气水分布模式及水侵动态,提出了构造高部位布井避水、降速控压控水和边部水淹井强排等开发技术对策,为塔里木盆地库车深层大气田的高效开发和调整提供技术支撑,并为国内同类气田的开发提供借鉴。

Abstract

Deep and ultra-deep buried reservoirs in Kuqa Depression are the most prospecting targets for natural gas exploration and development in Tarim Basin.These gas reservoirs are characterized by huge reserves,deep-buried formation (more than 3 500m),high temperature and abnormal high pressure,well-developed natural fracture,and complex gas-water distribution.The development practice shows that water invasion is occurred frequently in some development blocks,and thus result in the sharp decline of gas well production and low gas field productivity.In solving this problem,this paper presents a systematic static and dynamic evaluation technology for deep-buried gas reservoir with active edge water or bottom water.The methodology integrates description of static gas-water distribution,micro-water invasion mechanism and dynamic evaluation of water invasion.Based on above research,the character of gas-water distribution,the law of water invasion and the technical countermeasures of water control and development is established systematically.The results show that the distribution of gas and water in deep-buried reservoirs in Kuqa Depression is controlled by matrix property and the development degree of fracture net together.The gas-water distribution pattern can be divided into two types:Thin gas-water transition zone type (good matrix physical property type and especially developed fracture type) and thick gas-water transition zone type.The difference of gas-water distribution and fracture development directly results in the difference of water invasion location and dynamic characteristics of gas field,which is manifested in three types of water invasion:Integral uplift of edge-bottom water,coning of edge-bottom water along micro-fracture zone and longitudinal channeling of edge-bottom water along large fractures.Based on the above analysis,the technical countermeasures for water control,such as well spacing at high structural position to avoid water,optimizing gas production rate to stabilize water and drainage of old wells at the edge,are put forward systematically,which provide technical supports for efficient development and adjustment of deep-buried gas field in Kuqa Depression,Tarim Basin,and also provide reference for the development of similar gas fields in China.
