摘　　要：水力喷射径向射孔技术是一种新的油气田增产及完井技术,它可改善储层渗流环境,突破近井储层污染带,连通远井地带未动用储层与井筒、扩大气井泄流面积,改善气田开发效果。白马庙蓬莱镇组气藏储层物性差,渗透率低、裂缝不发育、含水饱和度高,非均质性强,储量动用难度大,气藏于2001年投入正式试采,目前已进入开发中后期,开采程度仅为5.6%,为提高蓬莱镇气藏采收率,增加了如泡沫排水、增压机和柱塞气举等工艺措施进行辅助开采,但是,这些工艺措施不能够从根本上改善储层条件,增大渗流面积,为此,在气藏开展了水力喷射径向射孔技术的应用,针对该项技术在现场的应用情况进行分析研究,从地质上评价水力喷射径向射孔技术在白马庙气田蓬莱镇组气藏的储层适应条件,为该技术在白马庙浅层气藏的推广应用奠定基础。As a new stimulation and completion technology, hydraulic jetting radial perforation can improve a percolation environment within reservoirs, break through a near-bore pollution zone, connect undeveloped reservoirs far away wells with wellbore, enlarge a drainage area,and finally improve development effect. With some characteristics of poor physical properties, low permeability, undeveloped fractures, high water saturation, and strong heterogeneity, the gas reservoir of Penglaizhen Formation, Baimamiao gasfield, is hard to be developed. A pilot production started from 2001, and now its development is in the mid to late stage with the recovery ratio of 5.6% only. To enhance this recovery, some technologies including foam drainage, supercharger,and plunger gas lift were adopted. However, these technologies can not improve reservoir conditions and enlarge seepage area fundamentally. Thus, a technology of hydraulic jetting radial perforation is applied. And its application conditions for Penglaizhen gas reservoir are evaluated.Therefore, this technology may be popularized for shallow gas reservoirs of Baimamiao area.
