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.
