200哈萨克STG盆地KYZ油田变质岩潜山岩性分析及测井识别

STG盆地KYZ油田变质岩潜山勘探处于起步阶段,完钻潜山井基础资料薄弱,特别是潜山取心井较少,不利于储层特征的研究,本文从潜山岩心分析入手,通过岩心薄片与测井资料的分析,建立了岩性与电性的关系,形成了岩性识别的图版,为KYZ油田以及整个STG盆地变质岩潜山岩性的有效识别及储层系统认识提供了依据。

以陕北志丹南部地区马五段上部碳酸盐岩为例,根据岩性测井曲线响应特征,利用交会图版法建立了碳酸盐岩岩性识别标准,岩性解释结果与实际资料具有较好的吻合度。     

雅克拉断凸潜山圈闭类型及特征研究

雅克拉断凸发育多个潜山圈闭,根据潜山地层和岩性特征将潜山划分为碳酸盐岩潜山和变质岩潜山。碳酸盐岩潜山已发现桥古和雅克拉两大潜山油气藏,都是海西晚期受逆冲断裂活动影响,断裂上盘古生界碳酸盐岩地层被剥蚀后残留部分地层形成的,储层类型为裂缝和溶孔,非均质性强。变质岩潜山储层类型以构造裂缝为主,针对变质潜山的勘探,加强对潜山的裂缝预测成为关键,同时应避开板岩、千枚岩等不利岩性。     

潜山岩石类型与测井响应关系研究

潜山油藏采用录井资料识别储层岩性难度比较大,并且具有一定的片面性。因此,本次研究利用测井曲线特征定性识别岩性,而后采用"岩芯刻度测井"的方法定量识别岩性。建立了不同岩石的识别标准,实现了定性定量识别储层岩性,有效指导潜山油藏地质特征研究,为油藏高效开发奠定基础。     

哈萨克斯坦A油田碳酸盐岩储层综合评价

哈萨克斯坦A油田为碳酸盐储层,岩性复杂,储层非均质性强,为解决以上技术难题,建立了一套基于岩石物理相分类、孔隙结构分析、储层参数定量计算及储层预测技术为核心的碳酸盐岩储层综合评价方法。通过岩芯和铸体薄片分析,确定A油田碳酸盐岩储层的主要岩性特征和孔隙结构,综合常规和特征测井评价方法对有效储层进行有效识别,应用孔隙度曲线交汇图版和Archie公式确定合理的储层参数定量计算公式。该区储层平面分布规律不清,通过敏感性分析及储层反演,有效识别了储层和非储层,为下步油气勘探评价提供了重要依据。

东营高陡构造下深层成像技术研究

当前,随着地震勘探程度的不断深入和对油气资源急剧增长的需求,油气勘探的目标逐步进入到复杂隐蔽性油气藏、岩性油气藏的勘探和对小尺度油气藏的精细刻划阶段,但对于覆盖广的深层潜山内幕所知甚少。在部分油井的钻探中偶遇了太古界油气储层,探索太古界内幕成为油气勘探的新机遇。这说明被忽略的太古界潜山仍然存在着实现其内幕成像的可能,但这些迫切需要现有的地震勘探技术对太古界潜山有所重视,在技术上有新突破。     

渤海湾盆地埕岛地区中生界潜山油气成藏控制因素分析

受多期构造运动影响,渤海湾盆地的中生界潜山油气藏勘探具有较大的复杂性和风险性。本文通过对构造演化特征、储层特征等的分析研究,得出含砾砂岩是埕岛地区中生界潜山的最好储层;明确了储层发育特征、断层侧向封堵、油气输导条件等是制约埕岛地区中生代潜山油气成藏的因素。埕岛地区主干断裂附近的中生界潜山顶部风化壳及内幕不整合面,是中生界潜山油气藏勘探的有利区带。

丽水凹陷源汇系统及其对储层物性的影响

储层成岩作用强、物性较差是制约丽水油气勘探的主要原因之一,通过对比不同物源区储层物性及岩石学特征发现,物源类型对储层物性具有较明显的控制作用,以花岗岩为物源的砂体具有更好的储层物性。通过对灵峰潜山演化特征及岩性识别研究表明,在古新统灵峰潜山是有利的物源区。结合已钻井、地震相、地震反演资料分析认为,西次凹中南部存在短轴和长轴两个方向的物源体系,靠近灵峰潜山是寻找优质储层的有利方向。

Direct observation of freeze-thaw instability of latex coatings via high pressure freezing and cryogenic SEM

Despite its industrial importance, the subject of freeze-thaw (F/T) stability of latex coatings has not been studied extensively. There is also a lack of fundamental understanding about the process and the mechanisms through which a coating becomes destabilized. High pressure (2100 bar) freezing fixes the state of water-suspended particles of polymer binder and inorganic pigments without the growth of ice crystals during freezing that produce artifacts in direct imaging scanning electron microscopy (SEM) of fracture surfaces of frozen coatings. We show that by incorporating copolymerizable functional monomers, it is possible to achieve F/T stability in polymer latexes and in low-VOC paints, as judged by the microstructures revealed by the cryogenic SEM technique. Particle coalescence as well as pigment segregation in F/T unstable systems are visualized. In order to achieve F/T stability in paints, latex particles must not flocculate and should provide protection to inorganic pigment and extender particles. Because of the unique capabilities of the cryogenic SEM, we are able to separate the effects of freezing and thawing, and study the influence of the rate of freezing and thawing on F/T stability. Destabilization can be caused by either freezing or thawing. A slow freezing process is more detrimental to F/T stability than a fast freezing process; the latter actually preserves suspension stability during freezing.

Gordon Best Paper Competition.     

Ethanol and (−)-α-Pinene: Attractant Kairomones for Bark and Ambrosia Beetles in the Southeastern US

In 2002–2004, we examined the flight responses of 49 species of native and exotic bark and ambrosia beetles (Coleoptera: Scolytidae and Platypodidae) to traps baited with ethanol and/or (−)-α-pinene in the southeastern US. Eight field trials were conducted in mature pine stands in Alabama, Florida, Georgia, North Carolina, and South Carolina. Funnel traps baited with ethanol lures (release rate, about 0.6 g/day at 25–28°C) were attractive to ten species of ambrosia beetles (Ambrosiodmus tachygraphus, Anisandrus sayi, Dryoxylon onoharaensum, Monarthrum mali, Xyleborinus saxesenii, Xyleborus affinis, Xyleborus ferrugineus, Xylosandrus compactus, Xylosandrus crassiusculus, and Xylosandrus germanus) and two species of bark beetles (Cryptocarenus heveae and Hypothenemus sp.). Traps baited with (−)-α-pinene lures (release rate, 2–6 g/day at 25–28°C) were attractive to five bark beetle species (Dendroctonus terebrans, Hylastes porculus, Hylastes salebrosus, Hylastes tenuis, and Ips grandicollis) and one platypodid ambrosia beetle species (Myoplatypus flavicornis). Ethanol enhanced responses of some species (Xyleborus pubescens, H. porculus, H. salebrosus, H. tenuis, and Pityophthorus cariniceps) to traps baited with (−)-α-pinene in some locations. (−)-α-Pinene interrupted the response of some ambrosia beetle species to traps baited with ethanol, but only the response of D. onoharaensum was interrupted consistently at most locations. Of 23 species of ambrosia beetles captured in our field trials, nine were exotic and accounted for 70–97% of total catches of ambrosia beetles. Our results provide support for the continued use of separate traps baited with ethanol alone and ethanol with (−)-α-pinene to detect and monitor common bark and ambrosia beetles from the southeastern region of the US.     

Methyl 2,4,6-decatrienoates Attract Stink Bugs and Tachinid Parasitoids

Halyomorpha halys (Stål) (Pentatomidae), called the brown marmorated stink bug (BMSB), is a newly invasive species in the eastern USA that is rapidly spreading from the original point of establishment in Allentown, PA. In its native range, the BMSB is reportedly attracted to methyl (E,E,Z)-2,4,6-decatrienoate, the male-produced pheromone of another pentatomid common in eastern Asia, Plautia stali Scott. In North America, Thyanta spp. are the only pentatomids known to produce methyl 2,4,6-decatrienoate [the (E,Z,Z)-isomer] as part of their pheromones. Methyl 2,4,6-decatrienoates were field-tested in Maryland to monitor the spread of the BMSB and to explore the possibility that Thyanta spp. are an alternate host for parasitic tachinid flies that use stink bug pheromones as host-finding kairomones. Here we report the first captures of adult and nymph BMSBs in traps baited with methyl (E,E,Z)-2,4,6-decatrienoate in central Maryland and present data verifying that the tachinid, Euclytia flava (Townsend), exploits methyl (E,Z,Z)-2,4,6-decatrienoate as a kairomone. We also report the unexpected finding that various isomers of methyl 2,4,6-decatrienoate attract Acrosternum hilare (Say), although this bug apparently does not produce methyl decatrienoates. Other stink bugs and tachinids native to North America were also attracted to methyl 2,4,6-decatrienoates. These data indicate there are Heteroptera in North America in addition to Thyanta spp. that probably use methyl 2,4,6-decatrienoates as pheromones. The evidence that some pentatomids exploit the pheromones of other true bugs as kairomones to find food or to congregate as a passive defense against tachinid parasitism is discussed.
