【摘要】：北部灣盆地烏石凹陷為復(fù)雜斷塊油氣藏,油氣勘探開發(fā)過程中,面臨鉆井工程風(fēng)險(xiǎn)大、測(cè)井取資料作業(yè)困難等問題,如何精細(xì)描述井旁斷層及裂縫等地質(zhì)體的構(gòu)造特征顯得尤為重要。聲波井旁地質(zhì)體成像技術(shù)中偶極橫波遠(yuǎn)探測(cè)測(cè)井技術(shù),有效地提高了井旁地質(zhì)體的描述精度。文中對(duì)井旁斷層的成像特征及偶極橫波的方位分辨率進(jìn)行了正演模擬和分析,利用研究區(qū)2口井的聲波測(cè)井資料驗(yàn)證了聲波井旁地質(zhì)體成像技術(shù)能夠?qū)园l(fā)育的小斷層進(jìn)行精確識(shí)別和描述。在油氣勘探和評(píng)價(jià)階段,該技術(shù)的應(yīng)用能夠優(yōu)化鉆井方案,避免工程風(fēng)險(xiǎn),提高鉆井效率,進(jìn)而落實(shí)可采儲(chǔ)量。
[Abstract]:The Wushi sag in Beibu Bay basin is a complex fault-block reservoir. In the process of oil and gas exploration and development, it is faced with many problems, such as the high risk of drilling engineering and the difficulty of logging data acquisition, etc.It is very important to describe the structural characteristics of geological bodies such as well-side faults and fractures.The dipole S-wave remote detection logging technique in the imaging technology of the geological bodies near the acoustic wells has effectively improved the description accuracy of the geological bodies nearby the wells.In this paper, the imaging characteristics and azimuth resolution of dipole shear waves are simulated and analyzed.Using the acoustic logging data of 2 wells in the study area, it is verified that the imaging technique of the geological bodies nearby the acoustic wells can accurately identify and describe the small faults developed by the wells.In the stage of oil and gas exploration and evaluation, the application of this technology can optimize drilling scheme, avoid engineering risk, improve drilling efficiency and realize recoverable reserves.
