The reef limestones are characterized by plentiful fractures and pore spaces. showing a nature of good reservoirs.
礁灰岩具有大量裂隙和孔洞，是好的储集层。An oil field consists of a reservoir in a shape that will trap hydrocarbons and that is covered by an impermeable or sealing rock.
一个油田由形态上会圈闭油气、并被不渗透的或封闭岩石所覆盖的储集层组成。The moment high pressure of magma intrusion caused brittle fracture of the surroundings mud rocks, and tension and compression fissures .
岩浆侵入活动大大改变了其周围泥岩的储集性能，对油气聚集具有重要意义。The further movement of the hydrocarbons into reservoir rock in a hydrocarbon trap or other area of accumulation is secondary migration.
烃类进一步运动进入储集岩石达到油气圈闭或其他聚集区是二次运移作用。After reaching the reservoir the composition of the drilling fluid may have to be changed to avoid clogging the pores of the rock.
到达储集层后，必须改变钻井液的成分，以避免阻塞岩石孔隙。Evolution of the Reservoir: Most oil reservoirs are created when a valley sinks and is flooded by the sea.
储集层的演化大多数石油储集层形成于峡谷下沉和被海洋淹没之时。The spatial arrangement of these Neogene reservoirs can be analyzed and described by using a logging- constrained inversion technique.
运用测井约束反演技术，对上第三系储集层的空间展布进行了分析和描述。non? sensitivity to its salinity, water quality, alkalinity etc. and the permeability of the reservoir is not influenced by . . .
其盐度、水性、碱度等为非敏感性，对储集层渗透性基本无影响。Using conventional well long data to calculate the conductance can be able to well recognize the reservoir type.
研究发现，用常规测井资料计算的导电效率能较好地识别储集层类型。
